I love this video. I always found bike assembly intimidating but watching this makes me confident I'd be able to follow the steps.
Very happy to hear that. Go for it and if you have questions ping me 🤜🤛
This video is absolutely fantastic, truly one of a kind. I find myself thoroughly enjoying every minute of it. The explanation of the "what, where, why" is superb, leaving no room for confusion. If only I had stumbled upon such a tutorial earlier, I could have spared myself the numerous mistakes I made during the assembly of my bike. Greetings from Serbia and keep it going with great content
Thanks so much buddy. Really appreciate the kind words and very happy to hear that you enjoyed it. More to come 🤜🤛
Fantastic explanation of the build well done
Thanks a lot. Very happy to hear that 🫶
What an awesome video, with the continued high cost of new bikes I’m going to give the Yoeleo r12 a go.
Thanks so much. Glad you enjoyed it. Still love my R12. A real fun bike to ride and the geometry also fits me like a glove. 🤜🤛
the best bike build video, It will help me with different frame and groupset but all the proces well explained :)
Thanks a lot. Very happy to hear that. Enjoy your build 🤜🤛
By far this is the best of the best build and review I ever watched for Ltwoo eRX.
Thanks a lot Logan. Glad you enjoyed it. Really love the groupset so far. Might buy another one for my gravel frame for some high stress testing.
Man! I do not know how it is possible for this video to not have more than 10 thousand likes... awesome build. Superb tips and advises through the building proces. Would have liked to see a little bit more about the bleeding of the front brake, but still: great video. Maybe you could try a 12 speed cassette eventually. It would be awesome to check that out also.
Thank you buddy. Means a lot. Hehe i think its better that you didnt see me in detail while trying to bleed the front brake. It was not pretty 😂😂.
I actually have a 12 speed cassette somewhere so could give it a try but dont have a 12 speed chain and i guess i would need that for a proper review. Lets see what we can do here 🤜🤛
Yes fantastic video! I found it totally absorbing. Not only did you cover setting up this particular bike, you also provided a step-by-step education in how to build up a bike per se. I will be using this as a future guide in future bike builds.
Thank you for going to such a lot of effort in making this vid. I'm grateful for every minute you put into it. Seriously,, its just the best.
Thanks so much Fabian. Very happy to hear that you enjoyed watching it and that it will be helpful in the future. Feel free to ping me in case you have any questions with your build 🤜🤛
very comprehensive setup video, dude. keep updating!
Thank you 🫶 and i will 🤜🤛
Amazing work.... 😍~ Loved the build and all the detail info that you've shared.
Thanks a lot Dennis. Very happy to hear you enjoyed it 🫶
Thank you for the awesome video, Michael. Enjoy riding! 👏👏👏
Glad you like it. Thanks a lot 🤜🤛
Great video. I have been looking at the eRX and you did a awesome build video of it.
Thanks a lot. A new in depth comparison video just came out 🤜🤛
Many thanks for the detailed and thorough review and instructions!
My pleasure mate. Glad you enjoyed it 🤜🤛
Super methodical and detailed build vid. Well done. One of the first for eRX I've seen.
Thanks a lot buddy. Glad you enjoyed it.
🤜🤛
This was such a wonderfully informative video. Can’t wait to see the review from riding!😊
Thanks a lot mate 🫶
Great comprehensive review! Looking forward to building up a LTwoo ERX groupset soon on my end.
Glad you liked it. What frame are you installing it on?
Thank you so much for the video!!! I really really enjoy this kind of long and very detailed videos 🎉😊
Thanks a lot. Very happy to hear that 🤜🤛
So looking forward to this one! Thanks man... Will snap later to work, this has priority! 🤜🤛
Haha i m bad influence 😂😂😂
Pretty nice, congrats
Thanks a lot 🤜🤛
Great Content well made. I enjoyed the sound of your voice also as the the background music. Thanks a lot for the explanations and the details.
Thanks a lot Oliver 🤜🤛
Because of this video I am now a new subscriberr on your channel.. Great video nice tutorial.
Love to hear that. Thanks a lot for the support. Hope you will like some of the other bike builds as well and of course the upcoming videos 🤜🤛
@klein-concept sure I'll watch your previous vids.
Seriously, amazing video. You've convinced me that (with the help of this tutorial) my two left hands can tackle my first ever bike build.
Very happy to hear that. It is good fun building your own bike. 🤜🤛
A premium video production / walkthrough for a premium superbike. Amazing work.
Thanks a lot 🤜🤛
Wow Michael, so detailed. Love it! I’m currently saving up for a maiden built next summer. This video has everything I need. Keep it up!
Thanks a lot mate 🤜🤛. Glad that this will be helpful. What kind of setup do you have in mind for your build?
@@klein-concept gonna go for a Chinese frame and steering (combo probably), all internal. 9velo wheels (love them!). Want to do a 1by built with a narrow/wide 53 front and a 12-speed electronic back. Bike to train with on the Dutch flats
@@daan.dejonge sounds like a great plan. Need to have a look at the 9velo wheels.
Fantastic video!!! Planning a build later this year and was waiting until LTwoo sorted issues with their first batch. Waiting for the ride reviews between the CZcamsrs (Trace Velo, GC Performance, Peak Torque, ect...). Will be saving this video as a build guide.
Thanks a lot. Also curious to see how this groupset will age. I like it so much that i think i will be building another bike with it. 🤌🤌🤌
Very nice, enjoyed the whole video
Thanks a lot John. Very happy to hear that 🤜🤛
Thank you for this great and complete video/review
Thank you. Glad you enjoyed it 🤜🤛
Great video very informative looks great 👍😊
Thanks a lot David. 🤙🤙🤙
That is not how you adjust the B-Limit screw on the rear derailleur. Your chain is way too long, you don't run it through the derailleur. The B-screw should be adjusted so that there is 5-6 mm between the largest cog on the cassette and the top pulley wheel of the derailleur, and NO more.
Thanks for pointing this out. As another viewer also mentioned this yesterday, I will be shortening the chain today by a couple links. 🤜🤛
Thank you, saves me from making the same comment
After using the washer on the drive side of the 24mm axle is the distance of the crank arms to the chain stays the same? 🤙
@@domestique3954 good question. Let me find out when i m back home later this week 🤜🤛
Watching this is super informative and kinda asmr-like making even the fiddly worksteps enjoyable to follow. Nice build and very clean look with the fully integrated setup.
Thanks a lot mate. Glad you enjoyed it 🤜🤛
Hey@@klein-concept, did you run into any issues with the eRX set yet? I'm unsure if I should be investing into Ltwoo for my own build considering recent experiences by China Cycling, Trace Velo and GC Performance with the groupset.
Since I went for a frame with full internal routing through the headtube rather than entering the frame on the side, I'm concerned mechanical shifting wont be working clean enough with the bending in the headtube/handlebar area which is why I would like to go for electronic shifting.
@@iTzRafaaaa hey, so far it is working for me but i have only out around 250km on it. So i would not fully rely on my experience with it here as there seem to be some obvious problems with some of the batches. I think if you have some time it might make sense to wait a couple months until L-Twoo have sorted out the issues or maybe consider going for a 105 Di2 as i have seen some discounts recently which have been pretty close to the L-Twoo pricing.
Basically this video have really helped me understand how to assemble my own R12 :D
Very happy to be your build manual mate
🤜🤛
Fantastic video! I’m building up a R12 aswell with the Rx groupset. However might upgrade to ERX after seeing everyone’s experience. Following for the update
Thank you. I actually also started with the RX group and was halfway done. In the middle of the build the postman dropped off the eRX so i decided to put this on 🫶
Might be the same story with my build haha especially since I have the integrated bar/stem. Going with elite drive wheels I think
For the integrated bar it will be a lot easier to go with the eRX.
Amazing. I love my rim brake Drive wheels. Might get some disk ones for another bike as well. They are so lightweight.
I am new to road biking. This is giving my confidence is building my own bike. Thank you
Yes 🫶. Happy to hear that. Ping me if you have any questions along the way.
@@klein-concept than you I will for sure.
I have the same frame and colour. Here in China the eRX groupset is $450 without the crank. Great video! Thank you
Thanks a lot. It is a lovely frame. Hope you are enjoying it as well.
450 for the eRX is a real great offering.
wow, this was awesome! thanks.
Glad you enjoyed it 🤜🤛
Awesome, Michael !! 👍🏻👍🏻
Thank you. There is also another update video on this now up on the channel 🤜🤛
Wow, amazing job mate! I was waiting for this video to see if the groupset works 😂 Enjoy your rides!
Thank you. So far i am really impressed about the performance. Gonna put some miles on it next weekend. 🤜🤛
@@klein-concept Do you know if Garmin is compatible? Also, what is the battery life?
@@Artemstorozhuk it should smoothly work with Garmin as well as it seems its just bluetooth standard.
Battery life seems ok so far. Only charged it when i got it so far.
@@michaelklein_BLKDRP interesting, when I asked about Garmin support in the store they told me it's not supported which surprised me.
Bestes Video was ich in den letzten Tagen gesehen habe 🔥🔥🔥
Danke dir Semih 🤜🤛
Very detailed and awesome build !!! I am seriously considering getting the groupset and this is going to be gold information !
Regarding the shifter bleeding, Shimano one's have some "burp" angles on the gen2 top port, maybe it helps to do the 45º up, 45º down pump pump pump and the gravity bleed.
Hopefully I can get it done :)
Thanks a lot Paulo. L-Twoo also released a new video on the process, which includes using the air whole at the top of the shifter as well. Maybe that s where the magic happens. I ordered another eRX groupset for the next bike so will also give it a try with the angles you suggested. 🤜🤛
Great video as always!
Thank you 🫶
Sehr nice! Really enjoying your videos!
Besten Dank 🫶
Excellent video. I want to build a bike now too! 😁
Hehe. Mission accomplished 🤜🤛
Good advert for mechanical + external routing. Surprised u dodged using the fully-integrated cockpit _seeing as how it is an instructional video._ Super video production tho
Hehe so true. Building a mech bike with external routing is so much easier and done in half the time if not less.
I went for their two piece setup as it was their newest handlebar at the time and i wanted to give it a try. Lots of other fully integrated cabling fun in other videos on this channel 🫶
Great job
Thanks a lot 🤜🤛
I was kind of expecting you to say when you couldn't push the fluid through, you forgot to release the clamp on the hose. Maybe because I have forgotten to do that more than once. LOL!🤣🤣
I have seen a couple of other videos on this groupset. They turned that screw out too far and it fell out. So, be careful.
Hehe also done that as well. Luckily not on camera 🫣. There is a new video from L-Twoo on the whole process and they also open another screw in the hoods that i was not using. So maybe that way it is easier.
Really enjoyed this video. Yes, B screw adjustment is compensating for a chain that is too long, never a good thing. Also, next time you fit a hydraulic line, put the olive in the shifter followed by the locking screw tightened just to the point where it touches the olive. Then push the line in. This avoids cross threading.
On another track, your chilling in Majorca video is on most days in my house thanks...
Thank you. Amazing tip to put the olive and screw in first. Makes so much sense and things a lot easier.
Very happy you re enjoying this one as well as using the Mallorca one as a screensaver 🤜🤛
Thank you for your excellent video! You singlehandedly did a better job than L-TWOO themselves at explaining this groupset lol.
For your next video, may I suggest doing a guide to the companion app's pages and functions such as updating the firmware? The individual gear indexing also looks super interesting and I'd love to see how an adjusted eRX handles shifting on a 3rd party cassette and chain versus Di2 which is of course non-adjustable. Funny how Shimano and SRAM don't let us individually adjust cog positions but Campy and L-TWOO do!
Maybe also do a slow-mo of eRX and Di2 shifting on the same Ultegra cassette and chain so we can see how both perform in a best case scenario for Shimano and see which groupset actually shifts faster/smoother (refer to Jon Maloney Cycling's video on R9270 vs RED AXS).
Or even installing Shimano or Magura mineral oil calipers to save weight and 3rd party pulley wheels onto RD to improve shifting even more? L-TWOO pulleys are 11T like Shimano, and some Shimano RD can even fit larger 12T and 12/14T pulleys on stock cage.
Thanks so much for the comment and great ideas for future videos. I actually have a slow motion side by side comparison of the eRX with my Dura Ace Di2 on the list. So that will be coming soon. Once there is a new FW i will make sure to cover that in a short video as well with some more details about the app. 🤜🤛
Great video, loved the shifting adjustment part on the phone app. I wish there were more info about the weight of the frame + fork + wheels etc… which you did for the stem + bars.
I think there should be more details on the Yoeleo side for all of them but you are right. Next time i will put all on the scale to verify their claims 🤜🤛
Dam, reaaaally tempting to get erx now... But, they are still dam expensive, so maybe waiting for it to mature a little bit more 😅. Been very happy with R9 hydraulic, didn't think i would like shift buttons that much but it has grown within me!
Thank you for creating such wonderful demonstration for these groupset!
Thanks a lot. Really glad you like it.
How is the R9? How was the setup for you? I know the price is not super competitive yet given some of the current 105 discounts but i would think the price might go down a bit after the initial hype 🤌.
@@klein-concept its been great with r9! I got it for under 200 euros for whole groupset (no cranks) so it was amazing deals for sure! But i still end up using 105 rd and fd for more precise shifting and also using slx calipers since my bike is post mount system 😅
All though i have my new chinese carbon frame coming up with flat mount system, maybe after that i can test the orginal brakes 😅
@@penzuugi Very cool. Yes i heard the FD and RD are not that great but amazing that you can pair their shifters with Shimano components.
@@klein-concept Yes, that was one of the main reason for me to go for this groupset is Shimano part of compatibility. Stock rd all though ltwoo said it was compatible with 34t cassette which they weren't, so i had to get 105 rd because of my silly cassette choice😅. But even though only parts of ltwoo that i use is their Shifters, but they are still pretty solid and i had zero issues so far!
Wow. Perfect step by step instructions. You might put some bike builders out of business!
Thank you 🤜🤛. Hope to get some people motivated to give a build a try.
Thanks for video
Glad you enjoyed it mate 🤜🤛
Great video, I'll definitely get one of the Chinese hydraulic/electronic groups sets in the future. Currently I am rocking a Sensah SRX pro x11 on my Gravel build. Perfectly decent for €95 but these new ones are a different league. Oh by the way, the cut angle of one surface of the bearing is called a chamfer.
Thanks a lot great you enjoyed it. Sensah also does some great groupsets. Rocking one of the 11 speed ones on another build as well. Think they are also releasing a hydrolic one.
Thanks for the chamfer comment. Always keep forgetting that word 🫣
@@klein-concept Don't worry your English is amazing, I'm British but have lived in Spain over ten years and I do speak Spanish nowhere near your level of English. Chamfer is a weird word, Dad was a carpenter so I heard it a million times growing up
@@user-tl1fh3ro6r thanks a lot. Hehe yes you must know all these professional terms for the various cuts and angles 🤌
Beware of those bottle cages, they aren't that strong, in fact one of them broke on me on a little bump. I think regular plastic ones are safer. Great video, loved the detail!
Thank you. I will be careful with those then. I hope mine are from a good batch as I was using them for the past years on another bike already. 🤜🤛
This video is fantastic. It´s one of the most complete videos of this groupset on the internet. After watching this video, i think ill buy this groupset. What i don´t know yet and i would like to know if the brake pads have to be of the ltwoo brand or can other brands of pads be instaled ? .
I´ll be waiting for videos like this
Greetings from Chile (South America). Nice content.
Thanks so much. Very happy to hear that. The brakes are actually compatible with shimano brake pads as well.
Thanks for the video!! I've been searching "ltwoo erx" daily to see if yourself or others have gotten to it yet. All looks very interesting. Am tossing up between eRX and a bigger jump to Rival or 105 di2 with the recent discounts/good prices on both, but this is sorely tempting for being cheaper and being able to run my current calipers, crankset + power meter, and 11s cassettes! Only the thought of waiting for any issues to be polished or ironed out as with the mechanical ones, but firmware updates are easier than hardware ones hey! Will be interested to see how it is after some riding in :)
Glad you enjoyed it. It is not an easy choice between this and a good 105 di2 deal. I have to say i love to be able to trim each gear individually. But Shimano is also a really safe bet. 🫣
i have to say at first i was super stoked to see electric shifting from ltwoo. but then i checked aliexpress: 833€, shipped to me mid october and not coming with a crankset or sprokets makes the 1120€ 105 di2 or the 1200€ sram rival etap - both WITH a crankset and sprokets and shipped within days - look like the better option... or the rival 1 xplr for 950 ;)
I agree. Their price is pretty high yet but i think mainly driven by demand. For example i paid 609 euros plus 25 euros import tax for mine which is still at least a bit below a 105 di2.
I guess the prices will come down over time.
Love the intro
😎😎😎
despite it's the long episode, really appreciate what you have done it, and it's really impressive~ definitely have to subscribe! I have been into all these non-mainstream components too, really an interesting, planning to get this interesting groupset.
However, can i ask what is the maximum tooth this rear derailleur support? if i remembered it correctly it is 32T. Possible to test it out with 34T if there's any limitation? Thanks a lot!
Thanks a lot. Glad you enjoyed the episode. Yes L-Twoo said its 32. I dont have a 34 (not even a 32) here to test it out. If i come across a one i will update here 🤜🤛
Excellent video. Very detailed. Thank you for spending the time to produce a first class product. I am wondering if you have any idea of how large a rear sprocket the derailleur can handle? I want to set one up with a 11-36t cassette.
Thank you. L-Twoo told me it can go up to a 34t but i think a 36 might actually also fit.
@@klein-concept thanks!
Great video! Thank you. Do you think the Ltwoo levers could be compatible with shimano disc brake calipers? When you cut the chain, you don't need to passe it thru the rear derailleur, at least that's shimano says.
Thank you. Yes i heard they are compatible with Shimano calipers. Asked L-Twoo about it.
Thanks for the chain tip 🤜🤛
Who is 'we'. I have not been waiting for this group set, quite happy with my current installs.
I think having a groupset like this on the market is a benefit for all of us. Independent what group you are riding. It increases competition and therefore forces the big players to either innovate or get more competitive pricepoints. So even if you love your Sram or Shimano setup i think this is still great news even for you.
And dont get me wrong. I also love my Shimano setup but looking forward to see how this will change the market dynamic.
@@klein-concept I still have not been waiting for this.
Awesome video brother!!!!! Very detailed “ I have the same bike and I’m going to switch to Di2 from mechanical. Your video is step by step easy to understand and follow when I get my new group set in to install,! 🙏
Wicked. I love the R12. Electronic shifting is a great upgrade. Glad you liked.the video
🤜🤛
Those big glasses are so intrusive.🤓
🤓🫣😂
Great video, and super detailed. I have a question about the handlebars/stem combo, is there space to use an outfront computer on the handlebar or did you have to go with one that goes on the stem directly?
Thank you 🫶. I mounted the one that came with the Wahoo Elemnt Bolt 2. Was tight but worked. Will also try to mount one of these generic outfront ones where you replace two of the stem screws with slightly longer ones and add a mount that way.
thanks for that
Glad you enjoyed it 🤌
It makes SRAM sound smooth!
What exactly do you mean?
@@klein-concept Sram is a noisey groupset. It sounded noisey to my ears.
@@marccarter1350 maybe you could have a look at the latest video i posted which compares the eRX and Dura Ace Di2. Think the audio might be a bit better there. Wonder if based on that you would still think its more on the noisy side?
@@klein-concept Yeah going to take a look. I am interested as i will be starting a new build soon. How much did the import duty cost?
@@marccarter1350 for some reason i only paid 25 euros import 🫣
Thanks, great video and good insight into the groupset. Shimano 105 di2 is pretty much the same price. What’s your take on the erx after a few rides? Go for the erx novelty or stick with shimano for reliability?
Thanks a lot. It s a very good question. So far i still really like it. Shifts super smooth and brakes well. I guess it comes down to how much of the drivetrain you need. If you have a cassette, the discs and a crankset i think going for the eRX is a valid option. Of you need a full drivetrain 105 might be a good option at the current prices.
Thanks for the video, well made. I have the LTwoo RX hydraulic group set and I find the bleeding is very critical. Especially the front one, for some reason. Did you do something with the air vent screw on top of the hoods? I saw an instruction video from LTwoo where they also filled that one with oil after the normal bleeding procedure.
Thanks a lot Ben. The video which shows the air screw unfortunately came out after my build so maybe that would have made things way easier. During my setup i was not using the air screw.
Awesome video!! I’ve been watching your videos recently. How’s the Ltwoo erx going so far? Would you recommend it? Im planning to get one.
Thanks a lot. I am currently using it on my indoor trainer. Still happy with it and I will actually be building my Yoeleo G21 with another eRX as well. 🤜🤛
Fantastic Video 👍 #Subscribed

There is a new short on my channel about the weight and component list. Have a look. 🤜🤛
Thank you, be safe and be happy!
@@maxim6278 same 🫶
I started building it today, but with a different frame.
haptic is high-quality, optically also on point.
problems so far...
Battery box rattles, had to help me with washers.
Bleeding the same experience as in the video, despite the premonition.
use ultegra brakes, but the behavior is the same, the preload screw is a mystery to me.
Worse, however, cracking in the left shifter when braking.
I contacted Ltwoo, hoping for a simple fix...
greetings to all, and to berlin...
don't let the lioness catch you.../inside Berlin
Interesting regarding the rattle. Maybe some electrical tape around the batteries could fix it.
But did you manage to get the bleeding done by now?
I think i have seen the squeeeking issue on another channel as well and it just disappeared over time.
Keep me posted how it goes.
Looks like you can setup this groupset to whatever count of rear cogs you want (up to 12), by playing with the micro adjustment of every gear. Can you confirm if this is correct? And maybe you could try and set it up with a 10-speed cassette in another video? It is interesting to know what would happen if the rear mech hits the limit screw when indexed for a 10-speed (but the software still allows for an 11th shift).
Thanks for this review!
Good question. Per default you are able to switch between 11 and 12 speed but you are right that it might be possible to hack it to less gears by using the same position setting for some of the gears.
Will need to give this a try at some point after doing some more rides on this setup.
Awesome build! Would you mind sharing a link to the bar tape you ordered?
Thank you. Yes this is the one. Definitely not as good as the real deal but closer to generic tape with some texture.
a.aliexpress.com/_Eu5vRx5
I’m very sure this video could already be the manual for the industry.
Haha 🫶🫶🫶 hope it will be helpful to some.
Kudos for a very nice and well produced video! Professional quality with great lighting and so on.
I'm wondering about the other tabs in the LTwoo app. What settings are under the Shifter tab and the Calibration tab?
On the Shifter page you can swap the functionality of left and right shifter with eachother. Guess that is helpful for e.g. UK riders.
Actually just tried going into calibration mode and it doesnt really do anything other than asking me to switch into the 6th sprocket but no further steps from there 🤔
good good job. 👍
Thanks 🫶
Regarding internal routing the bar its significantly easier if you put 2 slight 45 degree bens in your shift cable. There is a fantastic video by Wrench Friday.
It allowed me to route 4 cables including 2 compression less housings through a fully integrated bar with relative ease.
Hey, thanks a lot for the tip. Will have a look at that video. Would love an easy way to route a internal cockpit. 🫶
@@klein-concept czcams.com/video/gt9cW70vFwM/video.html
Thanks a lot 🤜🤛
I would have liked to see the rear derailleur from behind the entire cage so I could perfectly understand if it shifts well.
Sorry for that. Now I know for the next time. Let me create a short the next days to show the whole unit. 🤜🤛
Mint review and bike build. But how did you set up the H and L limit screws or did you do this manually with the two limits screws after shifting into the appropriate course
Thank you 🫶. To be honest i didnt even touch these screws. In the app there are also limit adjustments which i used to make sure the chain stays on the cassette on the outer positions.
Can you use either or? Have you been out in the wet? Reports of erx failing after heavy rain seems to be an issue and going to sleep mid ride etc. I so want to pull trigger in buying groupset. Btw again great video.
@@chrismadden9126 i guess you could do either or. For me it worked out of the box with no real need to adjust limits on the hardware. Only did it in software additionally for security.
I have not been out in rain yet but did not have any issues with sleep mode. Also a new firmware came out yesterday so maybe that addressed some of the issues.
That is good news. Well consider me subscribed. Looking forward to long term review
@@chrismadden9126 thanks a lot Chris 🍻
I think that Luke @ Trace Velo had an issue with bleeding the brakes also. I think that it had something to do with the spacing of the olive on the brake tubing, in relation to it inserting into the brake lever?
Hey Thomas, thanks for the tip. I have seen that video. Think it was on the mechanical version. I kept that in mind when putting all together but didnt have the issue he has seen. There is now a new bleed video on the ltwoo youtube which mentions to use the other air opening on the lever. Guess that might have helped to get the big air buddle out that i guess i was dealing with.
Hi, so u think to unscrew almost max each brifter lever prior to bleed the brake is mandatory? What a nice video, great
Hey, i would say that its only important if you have a problem bleeding them 🤜🤛
But things happen with other try to install it! Almost had same isssue when installing the brake.
@@yudityanefri3409 i for example didnt have an issue with the right shifter as the screw was already screwed out but the left one somehow had it a bit screwed it.
The pronlem with this groupset is it's still very much in a beta stage. On top of that uou can get parts from an online retailer which ducks because if you brake a shifter or the rear derailleur you cant just buy the one part. With the big name brands i can buy screws,springs, hoods etc easily and if i need warranty service it a few days turnaround.
Why would you think it is still in beta? The groupset has been teased over half a year ago already so i strongly assume that there has been plenty of testing along the way. But still you have a point that it is a first generation product for them which will always leave lots of room for improvement as well as the problem with getting replacement parts. But i hope that we will see some distribution in europe soon.
I love the way you perform how to build Chinese eRX LTWOO on a road carbon bike I’ll give you a 5 star Now we’re are you base need to have a bike like that , if possible can I order it from you
Thanks a lot 🫶. Very happy to hear you liked it. Unfortunately I am not selling bikes but building them for myself 🫣
Would love to know how well the R12 frame was manufactured - how round is the BB, how well aligned were the brake caliper mounts, were the dropouts aligned, etc. The only reason I haven't ordered one is because I don't want to wind up with a creaking BB that I can't "fix", incessantly noisy brakes, and so on. I've had bad experiences with this, and I'd imagine that trying to open a warranty claim would be a bigger hassle than it would be with "western" frame manufacturers.
I was already riding this frame for at least 6 months last year and didnt have any issues. No creaking and easy setup for the disc brakes. I know what you are talking about as i also had a couple of noname Chinese frames and some of them mainly had an issue with dropout alignment and messed up break mounts. This is not the case with this one tho.
Does the front derailleur trim when going up and down the cassette? I heard that LTwoo had to remove it in one of their latest firmware updates... :/
Yes they had to remove the autotrim but you can easily trim it by just pressing the shift button again.
Very nice, thank you! My own notes, in case they're helpful to anyone.
More light would help, for eg when screwing the brake hoses into the shifters, it's quite dark.
My EZMTB bleed kit from Aliexpress doesnt seem to have the right adaptor to screw into the brake calliper. the body of the adaptor is too wide and the threaded bit doesnt make contact with the threads in the calliper.
TBContinued.
Thanks a lot for the feedback. Yes i need to work on the lighting a bit as i agree its not properly lit in some situations 🫣
For the kit. Did you have a look at a regular sram bleed kit?
@@klein-concept my kit has a dozen little thingies so I think it includes all possible formats. If I could machine down one of these thingies I could access the thread, atm the body of the thing is too wide to enter the hole, and the threaded bit doesn't get to the threads in the caliper. It's supremely irritating because it's a problem of a fraction of a millimeter
Ah so the tread might fit but the material around it hinders it. Might be worth then to look at another kit. Sounds like lots of headache to make the one you have fit.
I'm surprised you "fixed" the chain tension by adjusting what I believe is the B screw. Unless it really is a fourth screwn (H/L limits, B screw and ?). Chain length is usually set without derailleur (chainstay length and number of teeths on chainrings/cogs). On mechanical groupsets if you end up adjusting the B screw to adjust chain tension you'd mess up the shifting. Maybe it didn't affect it because it's an electronic groupset here? You usually want the top pulley wheel to be as close as possible to the cassette (adjusted via B screw) for faster/smoother shifting.
Great video, sorry if that sounds like I'm an armchair mechanic, I'm just being genuinely curious :)
Hehe no worries at all. It is a valid comment and i already shortened the chain this morning and brought the b screw back so that the chain is back close to the cassette again 🫣
@@klein-concept Thanks for the quick reply, hope the groupset is still going great, we need more content like this :)
@@becyk_du_quebec yes. Went for a 1h ride after work today. Still shifting smoothly. Will compare it to my Dura Ace Di2 next side by side.
Nice guide, but one thing bothers me in your video. When using a torque wrench, the key is how you hold it, and you grip above the handle, which changes the point at which the wrench "jumps". Please note this for the future :)
Ups. I didnt know that. Thank you so much for mentioning this. Will keep my future components safe 🤜🤛
Michael I have a question about a part in the box that the Yoeleo instructions really don't explain. The thin half shim that fits the steering tube registration marks of the spacers. What is that used for?
If you are talking about the c shaped shim I think it is a spacer to not have the cap rub against the frame when steering.
@@klein-concept Coolio! Just weird it is not on their illustration in the manual.
@@klein-concept I think I figured it out. It comes installed with a 0.5mm shim, and there is an extra 1.0mm shim in the kit box.
@@jespernohr ah i didnt even notice that they are two different ticknesses 😂😂
Hello My friend, I just receive my eRX groupset, and I have a question how do you unlock the breaks levers befor installing
I dont fully understand. Which part are you trying to unblock?
Ltwoo just released a proper brake bleeding instruction and yours is different, they have this called vent screw and you release some pressure inside. Or it doesn't matter?
Yes their video didnt exists when i was building it. Maybe it would have gone a bit smoother using that extra screw. 🤜🤛
Super Video! Wie schwer ist das Bike?
Schau mal in meinen neusten short. Da hast du dir komponenten liste und das gewicht zusammen am start 🤜🤛
How is the groupset holding up? I am tempted to get the ER9 version :)
Working well for me so far. But i m also only around 300km in on it so far.
Happy to find this video, cause I'm interested in this groupset. I have several questions, maybe somebody can answer.
1. What is the maximum capacity for the rear cassette? I have to build a custom bike for youth gear meters of development (7,62 meters) and the best cassette would be an xdr 10-36 cassette for my envisaged configuration. But, does it work with 36 teeth?
2. Can it be configured as an 1x? So, no front derailleur?
3. Can you not only adjust, but save configurations per wheel in the app? Let's say I have two rear wheels: one has a 10-28, 12 speed cassette (for time-trial), the other has a 10-36, 12 speed cassette (climbing, do-it-all). I'd love to be able, when replacing the wheels, (between races, or during the race, if disaster strikes), to have the settings adjusted and saved in the app for each wheel, and by simply pushing a button, to recall the settings of the rear derailleur from one wheels to another. Something like two or three presets saved somewhere, as I can do with my car's driver seat: it has two positions adjusted electronically, one for me, one for my wife - by the push of a button, I switch between the two positions.
Thanks!
Hey, thanks a lot for the comment and let me try to answer some of your questions.
1. The L-Twoo support just confirmed a max cassette size of 34.
2. If you are ok to have the buttons still on the left hand shifter you could just install it without the front derailleur.
3. That is a great idea to have something like presets for different setups. Currently the app only supports one setup.
I guess that If it works with 34, it should work with 36 as well, even if unofficially. Nonetheless, it seems clumsy to me to stop at 34, when the XDR cassettes are 10-28, 10-33, 10-36. Not to mention that there is a Shimano 11-36 cassette as well (typically employed in CX, but sometimes you can encounter it in grand tours, for climbing, at a pro level).
@@scherzo0o yes i agree. It is just what their support told me. As you say there is a high chance that 36 would still work anyways.
going to stick with the mech shifting.
Nothing beats the reliability of a perfectly tuned mechanical setup.
Thanks for sharing so the eRX also comes in 11 speed? I thought it only comes in 12 speed version.
You can actually switch it in the app from 12 speed to 11 speed. So works on both systems. I set it up as 11 speed so i dont have to get a new cassette.
@@klein-concept ooh didn’t knew that. I will wait on the long time review. I’m looking to build a new more modern bike.
Where I live (Curacao-Caribbean) we don’t have that much season changes.
But I do have a Bianchi 928L (carbon)which I use for everyday rides. (Group rides and races) and I have a Concorde Mistral 340 (aluminum) for off season / rainy days. Both rim brakes.
Maybe I will switch to disc. For both. I don’t know yet, maybe later on
Lovely setup. I wish they would make the eRX for rim brakes as well. Seems like you re also a bit of a rim brake fan.
Hello, what kind of Kassett does it takes ? UP to 34-11 ? I'm thinking of a Gravel Bike.
Yes L-Twoo confirmed that up to 34 will work but i think you might be even able to squeeze a 36 in there. But no guarantee.
