Thank you all for watching and I will see you all in the next video :)) - Zábava
I hope this video helps :)
just wondering is the stem that comes stock a - 6 degree or + 6 degree cheers ?
-6 😁
Great video! Thanks :) I would like to drop down on my S-Works Venge. Can you tell me which spacers/ size I need and where to find them?
Thank you!! Very helpful!
Thank you! I just got a new bike with an intergrated cockpit. The height wasnt to my liking so when I attempted to adjust it, I started to get freightened. This video has helped to get the correct items. Cheers.
Thank you gc performance! I appreciate it! Alot of people will be happy with this tutorial! this wine red color is growing in me tho! thank you microtech!!!
thank you so much and I am glad to help out
Ahhh, I see a Microtech and a Tarmac, i'll leave a like. (great knife choice)
Lol thank you so much. I’m a huge micro tech guy. Use it for all my box openings lol.
Ya I said oh just throwing in a little flex with the Microtech!
looking forward to the sl7 recall vid :)
Very helpful video thanks! Just bought the SL8 pro here in Germany but this comes with the "old" SL7 Cockpit (as you certainly know). But I'm also thinking about making some changes with the spacers. Thanks again, cheers
you are welcome
Thanks for this vid. And, sweet Microtech!
thanks so much!!!! I am suprised so many people know the knife
Interesting. I'd like to do this. Very nice... Well done!
You should!
Thanks for the vid! With the longer recall plug in the SL7, can one just leave the chimney as-is and don‘t have to worry about structure / support since the long plug now covers full length of the tube?
Does this technique require the carbon fibre spacers to be as you’ve shown?
Or can this be done with the spacer kit specialized sell?
e.g. Specialized My19 Venge Headset Spacer Kit?
(In a case of a 2019 venge)
@GC, If you had removed one more spacer, and then cut the steerer tube, would it be necessary to cut/adjust cable length too?
You wouldn’t need too
Thanks. Can you advise the best way to measure the steerer prior to cutting on the SL7?
Make a line right above where the stem is and cut a couple millimeters under thag
Brilliant, really helpful thank you.
You're welcome!
Helpful. Thanks! 👍
No problem!
2:57 that is some serious cable kinking.
its hydraulic fluid do its not bad at all there is a fluid in there and doesnt matter that it is kinked
Not sure if I’m going off on a tangent, but when dropping the stem, necessarily that’ll result in reducing the space between the top of the knees and the torso, at the top of the pedal stroke (closing?) the hip angle to some extent.
Countering clash of knees to torso in the more slammed position could be by a)reducing stem length? b)reducing crank arm length? c)reducing biscuits and gravy?
Also,
could the same “experiment” with lower position procedure be followed for 2019 venge?
Regardless, fantastic work in this and all other videos, many thanks.
thanks so much!!
Is there typically enough slack in the brake housing to swap stems to go up 10mm from like a 100 to a 110 without having to redo the cabling?
sometime syes depends on the shop who builds it, I usdually shove cables into the bars to add excess amount if we do want to make the stem longer......
Great video. If you only want to remove the small spacer (0,5 cm) do you still need the special cap?
yea for sure, any spacers you remove you wil have to cut something off... it is cut so close right now that there is no wiggle room
whats the performance benefit of the swapping out the ratchet? Is it the same one in the CLX wheels? What's the expected gains, as I have thought about upgrading mine In my Pro
you would get a better pedal stroke annd less dead spots in between and more engagment for climbing...... you do get a little tiny more drag while coasting but I mean as long as your pedaling..... there is no downfall to it
Hi, very helpful video.. Can the steerer tube be shortened by cutting without disassembling it from the frame?
It can be done, but you have to use a small saw guide and the remaining amount of steerer tube needs to be at least long enough for the saw guide to clamp on.
I got myself a brand new SL7 tarmac, when I got it I noticed that the wheel wasn't quite lined up with the bars, therefore I realigned it. Now when I turn the bars I can hear a hissing, I didn't thighten the bolts too much, the top one a bit tigheter than the pinch ones, pinch ones are just snug. No play in the headset.. Any suggestions or this is expected behavior? Bare in mind I haven't ridden the bike yet.
Is there typically enough slack in the system to at least get some fresh grease on the upper and lower headset bearings?
very rarly, you might be able to get away with a grease gun on the top but I do not knwo about under neath
Do you have to re-bleed the line if you decided to cut the steer tube or do you just cut it without taking the fork out of the frame?
so you can get a saw and jsut got it while it is still attached to bike, you just have to remove at the spacers and stem and be very carefull on the cut and have someone hold the bike..... I have done this before but the real way to do it is, to un hook the brakes and pul the fork out and then have to re run the cables through the bike, if you are carefull enough someitmes you dont have to rebleed brakes on new connection....
Do you have the top cap and the bottom screw piece for the cable in stock ?
I do not but call any spewciqlzied dealer they should be able to help
Thanks for your vide.
Where do you have the replacement spacers from?
And is it neccessary to put them on top?
you can order online or any bike shop
What is minimum height of the spacers on SL7 ? The first cover on headtube must always be installed + one 0.5 spacer (the first under the stem) ? Right? What is the total height excluding headtube length?
That's right.
hi there! could you fit the tarmac stem into a sworks venge?? I have a sworks venge and i need a 90mm stem and it seem way easier to find the "tarmac 90mm stem " would it fit my venge? kind regards!
yea it work but ti doesnt match the fit of the spacers, btu stil works
Do you have a link to buy the stem and spacer kit? I have the venge.
Hi what do you have to do withe front brake line to replace/service the headset bearings
It needs to be disconnected, the bike will need to be recabled afterwards.
Hi GC Performance. I own a 2020 venge frame. Need to change stem but not able to find one in correct length. Do you think can use SL7 stem with Venge spacers ? Some say the spacers wont line up properly. Would appreciate ure thoughts !
It won't, but if you use the Venge's other headset cover (the one with three holes, two for the brake hoses, one for the Di2/EPS wire) alongside a bunch of regular round spacers, any stem is compatible with the Venge.
What size diameter and thickness are those spacers?
Hey GC, with the original top cap and cover. do you need to use that specific top cap for the cover to clip in? Or is the top cap not involved with the integration of that plastic cover?
Yes, the stem cover clips into the top cap, but there's another version of the stem cover that has a hole up top, allowing you to use any top cap you fancy.
GC, what’s the size of those spacers? It’s a regular spacer you add to any bike?
yes theya re normal inch and eigth I believe
Hi, where did you get the alternative cap cover from? Thanks
it comes with every sl7 parts box
love this channel even tho i dont have the top of the line bikes.
Thanks so much!! and I dont have them either I jsut get to work on them so we can both droll together
@@GCPerformance18 no problem love the bikes u work on
As per Tarmac's user manual, a spacer bigger than 5 mm shall not be placed above the open stem cover. Is it because of the top cap bolt's length? And what are the risks of installing a spacer bigger than the recommended one? Thanks.
dont worry about it, as long as you tighten the pinch bolts on the stem to the right torque readings I have slammed my stem and rode with all the spacers on the top no worries at all
@@GCPerformance18 I tried this today and was wondering the same after noticing the comment in the Tarmac user manual... I think in theory you could remove all the spacers from below the stem, and then the stem would be gripping the steerer tube below the expansion plug... isn't this a problem? I just slammed mine by 15mm but this is a pretty crucial part of the bike so don't want to F something up and have a life altering crash as a result....lol
@@IPAColosseum On the safer side of things, ideally you want to clamp the reinforced section of the steerer tube. Specialized's expander plug is a little taller (if not just as tall) than a stem's steerer tube clamp.
You also may have heard of people deliberately running long expander plugs for this purpose.
Planning on replacing my stem from 80mm to 100 or 110mm, would there be enough slack on the cables for the longer stem? Thanks!
there suualyl should be enough slack, when I build I shove extra cable in the bar for that reason alone
@@GCPerformance18 great thanks!
Hi buddy , what size are the stem bolt screw size ? For the stem cap screws ? Is it a M5 or M6 and how long is the screw ?
I think it is m5
Ah you swapped out the cap thing to the one with the hole in the top. Wondered why i had both in the box.
Have you traveled with a SL7. How hard would it be to drop the bars for a bike bag? Also what ratchet would you need to upgrade the Rapide CLX hub?
yes it is fine, just get a big enough box or bag where you can take the handlebar off, and put to the side, you need the 54t ratchet but the EXP version
@@GCPerformance18 does the Rapide CLX come with a 36 or 52t ratchet?
@jj4996 the CLX wheels come with a 36t ratchet
At first when you said loosen the 4 front stem bolts, I was like "Huh"... lol, good catch though. Great content brother!
#RobbArmstrong
hahahha thank you!!! I hope you enjoy it
Could you post a video with the Roubaix 2020 with FS2.0 and the Tarmac SL7 stem? Curious how it will looks since since the future stem is only available in 6 degr and tarmac sl7 stem 12 degrees. Already installed lower top cap and hoover bars replaced with standard spesh bars
lemme see if I can make that happen
@@GCPerformance18 would be great! Know about a lot of roubaix owners who are thinking of installing a SL7 stem
How many spacers can I put on top of the stem? Because the manual says only 5 mm.
Thanks
thats what they recomened and yes for saftey issues yea, but I have seen full chimneys on there like full slammed with all stock spacers on top, and people have ran them for a while
Push the back bottom portion of the cover with your thumb right above the top spacer and the cover will pop right off without a tool!
Great info thanks so much!!
I don't recommend do this without cutting short brake hose. because most BSA BB don't have a "cup" inside the frame. So if you just push down the stem, brake hose will be lowered too, and it's very likely that brake hose will touch the spindle of crankset, and rub it.
I know this because it happens to my bike.
sooo, this is where the bottom bracket comes into play, shimnao and sram stock bb both have plastic sheeths covering them so there is not direct contact with a rotating spindle...... but if you use an aftermarket bb or maybe an installed wrong one then yes this is possible.... also the cable slack should be allowed mainly in the handlebar to hide excess
How low you can go before deciding on bar height because of the compression plug length? I assume you should not be riding with stem clamping carbon steerer below the compression plug.
Your fine. With specialized the steerer plug is deep as is but I mean as long as you don’t over tighten it there are no issues with it. I have done it to my bike and also customers bikes. There are no worries. It is thick there
@@GCPerformance18 thank you.
What size are those spacers?
Hello what degree is the SL7 stem? It looks zero degree? Am I correct?
How do I get one of those Park Slider Knives/Stem Cap Remover?
lmfaooooo just go to your local gun shop and it will run about 300 hahahaha
Is there any performance in changing the ratchet in the rear hub?
so, the only benefit they say is you get more points of engagement, so less dead spots in the wheels when applying power so better for climbing, and maybe for up out of the saddle for sprinting, but the down side is, you have more drag because of all those points of engagement for descending down a hill, so you would in theory be 54t engaging downhill.... i dont have hills so we are always pedaling but even now specialized made there stock wheels come with 36t ratchets, and peopel run i9 wheelss
Hi GC,
thanks for the great video!
Can i ask how tall you are and what your leg length is?
You said the bike is 52 - I'm just curious if I am going to order the right size. :)
So this bike was a customers bike. Not mine, I ride a 56 and I’m 6ft tall
I'm 5'7' and ride a 52 Inseam is 31. I could also ride a 54.. I need 15ml spacers under the stem on the 52 If I rode the 54 I wouldn't need them. Make sure you get a fit.
If you cut off a spacer how is it still flush?
You can also keep the fork the way it is to sell your bike more easily later. But bikes are supposed to be ridden I guess, not sold.
yea I always recomened it but for sure peoiple dont like the look and cant go too long until they decide to cut it lol
Yep helpful thnx
What is it that you changed in the hub to make the sounds louder?
its a 54t ratchet only for dt swiss
does the round spacers have to be carbon only or can they be aluminium?
They can be aluminum too
Nice Microtech OTF knife ! ;)
Thank you!! its my dialy driver at the shop I buse the hell out of it
@@GCPerformance18 i'm not sure to be happy to hear that... haha
i'm also a knife guy (and road bike enthusiast of course) and i never abuse my blades.
I mean by that, i don't let the edge getting in contact with hard materials like metals, stones (things you can't cut) or heavy prying with the blade (what you did in the video was fine for me).
But no problem with materials like wood, hard plastics or so.
Yea just I use mine as a glorify box opener or to remove labels from product lol
Just wondering, do you have to use spacers? What’s the risk of not using the spacers?
you need to, the fill up the empty space, so you run the risk of the fork being able to move up and down if not filled by spacers
Wondering if my bike is using FSA Acr headset, can I use SL7 or Venge stem ? Does the cable integration compatible?
No it needs to be a specific bike model for the integration cables. The stems can be used but not ran like the sl7 or the Veneg
@@GCPerformance18 mine is now with FSA Acr stem but too short, looking to change Venge stem as I like their integration 😅
Hi GC, Where can I buy that stem cap with a hole? Im based in UAE. Thanks
reach out to your local specialized dealer they sell it as a kit for the tarmac sl7
Sorry for a question, did you have the chance to mount the Aerofly II handlebar with the mechanical shifting? Because i would like to mount it on my Taramc SL7 Expert with mechanical Ultegra.. Many thanks in advance
i have not ran it yet but I know it is possible because I have seen bikes with it done.... so best of luck
@@GCPerformance18 Thank you very much
You can check out the build I did last September on my IG. (@ngyongling53)
@@yonglingng5640 thanks, i think i found it on your photos, is the black/ice-white sworks frame, right? Really cool!
How was to mount aerofly with mechanical cables? Hard or quite simple?
@@Andrea-uc7dy Yup, you found it.
In terms of difficulty, it certainly isn't easy, but using an old shift cable to route the shift housing does greatly simplify the process. This trick has helped me route several bikes and handlebars with ease, I almost didn't need my Jagwire internal routing tool.
Hello can you help where can i find stem cap of sl7 around asia or specifically at ph? Thanks
they come with the bike
Next SL7 video to show us how to cut the steerer tube without take the fork off completely 😄
lmao I have done before but I dont think i want to show it because everyone would hate me for it, there is a lot of procise cutting lmao
When you cut the fork, how much lower should it be to the steam?
The distance between the top edge of the stem and the edge of the steerer tube should be 3 - 5 mm. If your steerer tube plug has a flange that rests on top of the steerer tube when installed, take the flange's thickness into account too.
The Specialized steerer tube compression plug's flange is a little over 1 mm thick, so I usually cut 4 mm below my first mark (the mark that's flush with the stem at the desired stem height), making the steerer tube 5 mm lower than the top edge of the stem. Once the plug is installed, it'd be about 3.5 mm.
yes what he said lmao
Hi can i know the diameter of the spacer and how many mm used in this video?
an inch and eighth I think i only used like 2-3 spacers I have no idea I forgot lol but go to any store they have them all
the spacer and covers look sick! but does it fit on an Allez sprint? I just like the look of it xD
it fits but ti does not look as good on the allez sprint
@@GCPerformance18 do you think i'd be better off a normal spacer and stem
@@fluxed2100 You're better off with regular spacers.
Does this work the same way for one-piecebars?
yes it does, buit the split for the spacers on the new sl8 are at a ddifferent point but you can see it
Does the third big spacer (the one below the two you removed) breakaway?
yes all the tarmac sl7 spacers breakaway so it makes it easier to lower
@@GCPerformance18 awesome! Going to slam my stem tomorrow! Hopefully my back can take it haha!
Can this integrated system be applied to the roubiax expert 🤔
No, the Roubaix can never run a full internal routing setup.
Do one for the Scott Addict RC.
okay I wil try my best
Great video. Can you do a Trek Madone?
if I can get one to do it on yes of course
I understand cutting the steerer tube. Is it just as safe to cut down a carbon seat post?
Yes it is, just remember to take note of the minimum insertion mark's distance from the edge of the seatpost, then make a new mark post-cut.
If it's an uber-lightweight carbon seatpost like Darimo's, no. It has a designated clamping zone, so the carbon's thickness is only thicker in that zone.
yes it is and like he said as well :))
thank you
@@yonglingng5640 I have a Syncros Duncan Aero SL from my 2020 Scott Addict RC Pro
@@GCPerformance18 You're welcome.
Can you do the same with an Addict RC please?
I will try my best, I have never done it yet but I think it is very easy lol
This reminds me, do u have any Aerofly II bars in stock yet?
came and went super fast lol
I went with Enve SES.
Can you put a longer stem without rerouting everything again?
yes you can as long as u have enough cable for th ebrake
It is the same way to do for a trek émonda sl6?
I havent done one but I belive so
Yes, the Émonda's spacers split in half.
Specialized manual says you can only put a maximum of 5mm spacer between the stem and the cap.
of course, that is it, but i have seen there own reps rocking all the way slammed,
@@GCPerformance18 If you are needing more than 5mm on top then you need to start chopping that steerer. Wouldn't want to violate warranty terms. 👍🏻
I would want to believe the cables now need readjustment 🤔🇯🇲
no not at all, its nothing the frame or the handlebars cant accommodate, the slack of the cables would go inside of the handlebar
i wish i have bike like that for my birthday this February 12 😔❤️
nope
What’s nice about lowering my stem is it doesn’t require a how to video. #sl6
hahahha touche!!
Somebody who can tell me where i can buy the stem cover?
any specialized store can get it
do i need a torque wrench?
yes it is always recommended to have one.... I work on these bieks all the time so I know what 5nm feels about
What degree is that stem? Is it a 6°?
yes
Can you do a video on changing the hub ?
Which hub???
@@GCPerformance18 any
Where you mention changing the teeth in the 350 roval hub.
7:30/8:19
Hello
Does it work for Venge as well?
yes same way
@@GCPerformance18 thank you so mycg
Hey what's th weight of sl7 pro size 52
I am sure I have done a video on the past I do not knwo off the top of my hand
My dude. If my mechanic were sitting on my top tube like that, I would be pissed
lmao, you dont like to share? but I mean I have been working on bikes for a long time, i dont have all my weight on there............it can take it, if it cant hold me kind of sitting on it how do you feel with your whole weight on the bike and hitting a pothole or a bump
@@GCPerformance18 If you’re saying you’re not completely sitting on the top tube then fair enough. And sitting on the saddle and sitting on the top tube are two different things. Your viewers would be ill served if they are to believe sitting on the top tube is ok
@@youngkim666 genuine question - why is it not ok? Just that I’ve sat on top tube for years when stopped briefly and I’m now curious about what damage I might be doing.
i need those top cap desperately :(
Cylindrical is less aero js
yes this is true but also being up super is less aero as well
It's already low as is, No need to get a back strain even more
lmao
the hoses are cnacked .... i'm sure his brakes doesn't work well anymore !!
always remove your handlebar and get help from a second person to hold the handlebar and always remove the bolt at the underside of the stem that holds the hoses
Hoses work perfect. Done this on more then 100 of these bikes. If you could only see the bend the cable has on the fork steerer. That’s the point of hydraulic brakes. It’s a fluid
Just lower... nvm, wrong video.
Hahahahaha got me good
don't hyper bend those cables.... kink city.
They are meant to go like that, that’s why they are hydraulic lines that can bend more then a normal cable and housing
Lowering the stem on a Tarmac SL7 does not require tools. Just ride the bike, the CF steerer will snap, and your stem will automatically lower. LOL 😆
Lmfao
Very nice 😍💋 💝💖♥️❤️
What size are those stem bolts?
I dont know, I think m6
