Thank God
Nice, but, i wish there's rim brakes' vir.
Good to see they're not dumping mechanical. Also the continued improvement in front derailleurs is welcome. I remember the bike I had in school in the 1980s, front shifting while pedaling under load was a guarantee of a chain drop or jam. By the onset of 10-speed groupsets, it was a grey area. With the 5800, mostly fixed. With the 7000 series it simply doesn't drop and now this is even better???
Full-internal bike with a mechanical groupset is a very cool feature!
Hello, is it possible to fit an 11-28 cassette with a 53T chainring?
Great to see Shimano offered a 105 mechanical. Not everyone wants a Di2 setup.
Well I think we all want it, we just can’t afford it…lol
@@adam_cosgrove Hahaha, accurate. 😂
@@adam_cosgrove fck essential electronic bike components
I don't want electronic crap
enjoy hearing clicking constantly from the mechanical version then @@interceptor7905
I used 105 10 speed for some years. Once adjusted, it worked perfectly forever. Smooth and precise.
We don't need more than 10 speeds. It's daft, the chains last 25% the lifetime of 10 speed chains. Hate the planned obsolescence in this industry
I ride Ultegra 10 speed 12 - 30 cassete. Perfect, and budget friendly.
Mountain bikes need more than 10 speeds because of the "cool" 1 by setup (they put the second chainring in the rear, 52t, fcs!) but road bikes are ok with 2x10
I have a 10 speed 105 bike and an 11 speed 105 bike. I swapped some high quality jagwire cables on the 10 speed and it's been flawless. The only gripe I have is the size of the hoods on the 10 speed. The newer hoods on the 11 speed are so much better in hand.
Same here.
Very smart of Shimano. 12 speed makes a lot of sense for non racers who want and need a broader range of gears + the quality increase.
No one on a road bike ever needs 2x12 gears unless they are racers, if you need a broader range, getting more gears isn't the first way to go
But I think spend more money on 2×12 groupset doesn't make any improvement.I would spend money for carbon wheels
@@user-je5po4nz9zsure I don’t need them, but I have an old Claris and an 11 speed ultegra, and I’d much rather climb the Buttes around me with extra gearing options to make the gear ratios smaller and easier to stay in a consistent zone/cadence. Using your logic, we should all be riding single-speeds because you don’t “need” more gears, they just make it easier.
@@user-je5po4nz9zplenty of racers don't NEED 2x12. And really, who needs 2x10 ffs? People WANT 2x12 though
@@KelvinSuddith no, you're inventing my supposed logic there, no need for that thx, i said you don't need 2x12, bc 2x11 or even 2x10 or 1x is just fine as long as its catered to your needs (by which I mean exactly what you are saying with consistent cadence) its much cheaper and caters to the same needs and range as a 2x12 setup would just "less smooth", if you need broader range the solution isn't more gears
Yay!! Mechanical shifting isn't dead! I have to say, I have been on multiple group rides where something went wrong with someone's electronic shifting, problems that were directly related to the electronics. In many of these cases, the person couldn't actually do the ride because they couldn't solve the problem. With mechanical shifting, about the only time things go wrong is when there is a crash. I LOVE my mechanical shifting. :)
Been on group rides where cables break.
What was wrong with their electronic shifting?
So YOU could repair for example a broken cable during the tour? :)
There always can be problems, no matter what you use...
Reminds me so much on the carburator vs fuel injection discussion in the motorcycle boards...
I'm thrilled that a new 105 groupset is available in mechanical. The cost of Di2 is certainly an issue, but ultimately it comes down to aesthetics: I just want my bikes to be analog. Electronic shifting is pretty impressive, but the performance gain is marginal, and I'm not willing to give up the very satisfying and informative tactile feedback you get from shifting mechanically.
I've always been fond of mechanical 105; it's honestly clunkier than Ultegra, you notice the difference, but it shifts just as reliably and effortlessly, it's fairly easy to maintain, and if something breaks, it won't destroy your budget.
There´s no gain in performance at all. Actually, the costs of manufacturing are lower on electronic than on mechanical, but they make muck profit.
I went from 6870 Ultegra Di2 to 105 R7000 mechanical, I’m honestly amazed how well it shifts, especially the front mech. Can’t say I miss the Di2
I went from Ultegra 6700 to 105 R7000. It’s better.
Is that now an upgrade or downgrade in your opinion? lol
Tell us about the pros and cons...
1st step in the right direction. 2nd step would be a rim brake version.
And 3rd step a brake version for my good, old travel horse ;P
When mechanical group set is more sophisticated and more complex to manufacture but is $1000 cheaper
Marketing bullshit - mechanical 15 speed is available for decades by using 3x5 without need to buy useless aluminium gears from shitmany .
@@szankony6276 Overlap. You only get about 9 gears like that.
@@szankony6276yeah not a fan of 3x. My road bike its 2x11 and mtb is 1x12. Perfect. I have a cheap 3x7 shimano Tourney. Not a fan of it but it works great as an extra bike
I'm sure some comments will still argue it's NOT the groupset of the people because no rim brake option
Well, and grand scheme it’s still fairly expensive. Are “the people” doing alpe d’huez? Really?
@@joeceronedoesn’t need to be alpe de huez to notice brake fade on rim. There’s some 600 foot descents that aren’t particularly sketchy, that still have spots where you do need to brake and you will notice the difference. It’s not an argument of need, it’s a simple fact that disc brakes stop faster, and with how much of us ride on open roads with cars that don’t consider us, I’d say it’s for the people to include upgraded braking.
Think average people don't deserve better braking?😂
@@KelvinSuddith Nobody is telling you not to buy disc brakes bro.
Some pensioners still cling to rim brakes.
If we were being honest, Tiagra is about where 105 was a couple of years ago and is even more affordable. 105 is the bottom of competitive, Tiagra is the groupset of the people.
I agree. I went from a tourney drivetrain to Tiagra and the difference is immense
Yeah , if I ever need to replace my 10 speed 105 I will go Tiagra.
I run 105 on one bike and Tiagra on another. They feel exactly the same and are both smooth and precise and never had a problem with either. Accurate comment you gave for sure.
Being on Tiagra 4700 I couldn´t agree more. DA is smoother, but if you think about people liking the Campagnolo "felling" Tiagra is is like that. More noise, more clank and crinck, but awesome.
I mean, modern sora is better than ultegra 20 years ago.
OMG that final number of 17s difference from dura ace to 105, and that being a ridiculous 3w is bonkers! We’ve really gone crazy when throwing cash at high end bikes…
High end stuff is kind of for professional racers and rich enthusiasts. For anyone just training or enjoying cycling, 105 almost seems too advanced already. But kinda solid for amateur racers.
I love that GCN has highlighted this fact. Many people overestimate the effect of bike weight on performance.
If you are putting down the pro level power numbers on serious long and/or steep routes, you've already invested in yourself in terms of training, so you might as well buy the pro gear. However, I do thing the average person who buys top end bike components is a dentist who cycles one Sunday a month to show off his skimpy bike gear to other dentists at a foppy cafe.
@@justtheotherdave working in the industry, wealthy people tend to put in the most miles. How? They can afford to not work as much as the masses.
Often high end bikes are not bought because the owner thinks it will make them much faster. They are bought because it's a high end indulgence that will not bankrupt them, unlike the Porsche 911 Turbo S that they dream about.
Glad to see mechanical shifting still being supported by Shimano.
Probably more accurate to say it's good to see people can still force the hand of big greedy companies, because the way Shimano went about this indicates on every level that they did not want to.
Marketing bullshit - mechanical 15 speed is available for decades by using 3x5 without need to buy useless aluminium gears from shitmany .
@@szankony6276 Quit posting this stupid comment.
At half the price or less of the electronic and free of being tethered to a battery, so long as it can hold its settings without regularly going out of adjustment, I'm there.
Even the 11 speed version isn't half the price of electric 105 (650-700€ in Europe compared to 1000-1100 for Di2), what makes you think that 12 speed will be half the price?
@@dainiusvysniauskas2049 Earlier this year I bought a full groupset of 105-11s R7000 for 400€, after some time 12s can be gotten for a reasonable price.
If you've got around £500-600 to spend on this "trickle-down" 105 (rather than 11s Ultegra), I'd rather consider going for L-Twoo ERX. It's £499 or 4498RMB and is basically the Chinese Di2 which can be set to 10, 11 or 12 speed as per your needs. Plus, it weighs about the same as or lighter than Ultegra di2. Throw in a mid-tier crankset, chain, and cassette, and you're looking at a total cost of maybe £700 or less. The performance of L-TWOO ERX is pretty good-I've tried it out, snappy, not too far from etap axs or di2, front shifting not as fast as both. Not saying I'd pick either 105 or ERX for a new bike build, but if I had to choose, I'd go for the Chinese groupo, while 105 is very reliable, it is not so much of a "groupset of people".
I hear the retail price of the entire bundle in Japan is 200k (Di2) vs 130k, so not much difference to the 11-speed generation.
You can get 105 Di2 for the same price at the moment
Ollie used to be the Presenter of the People, but now he's too good. So I guess that designation will default to Lloydy.
You mean . . . "trickle down"?
It’s been a year since we last saw Lloydy - surely he is due to appear in another video soon
Cannot be a groupset of the people without a rim brake option. People who have rim brake bikes do not want to throw the bike away if they need to get any new parts 😢
11 speed parts will be available for a looong time
It's because of this that I'm thinking of maybe buying a dura ace R9100 groupset for a future bike in case I want to upgrade, since it's the last, latest and greatest mechanical rim brake option.
Plenty of hydraulic rim brakes available, don't see the problem.
@@matt.3.14 Huh? IIRC Magura did try an experiment with hydraulic rim brakes, but it failed
Ebay
Nice, might go for that one on the next upgrade. Also, I am now very well hydrated, thanks Ollie.
Good to see Shimano offering shorter crank arms. I use a 160mm 105 12-speed crankset on my 11-speed groupset. No issues in noise or shifting 👍🏻
Smartest Shimano decision a Long time!
Di2 105 is great, but it's also really expensive. Good to see them release a mechanical version. If the whole 1/3 the cost carries through the rest of the components, then the Groupset of the People has indeed returned.
Well, the cassette, chain, crankset and calipers are exactly the same parts as the DI2 105 groupset. I don't see they would be any cheaper in this case.
Glad to see a 12 speed mechanical groupset.
Ollie, you told us to sip a brew each time on hearing "trickle-down tech". Glad I was home, you left me quite tipsy.
I want the cranks! Love the simplified look to them.
absolutely fantastic! very good news!
Awesome! Thanks Shimano for this! 👏
Excellent. The 12 speed mechanics Shimano groupset on my MTB is really nice so no surprise this is decent.
Excellent video. Thanks!
thank you glorious Olli for your 105 review & yeah great to see the old dog back with a revamp to bring it into 2023, as it is the start of the beginning for many who fancy sticking their toe into the world of competitive racing, a well tuned & looked after 105 groupset will indeed keep you in the mix, yeah it's a little heavier as Olli pointed out for those mountain passes but let's be honest if that slight weight increase is holding you back then do a few more extra squats in the gym,
all in all it's always been a great race entry level race groupset that i myself have used & smashed my competitors on superior groupsets many a time.
Very nice. It will be the groupset on my next road bike build :)
Really glad to see a mechanical 105 12sp but kinda happy it came out a few months after i got my 105 di2 bike. Digging di2 a lot, a real lot, but prob wouldn't have done it had a mechanical version been out.
Groupset of the people is back. Nice.
That ORBEA is 😍WOW
Its great they are offering a more affordable option. Slightly off topic, I'm running current 105 with an 11-42 tooth shimano cassette (I'm old & need the granny option on the hills occasionally). The rear derailleur works fine in all gear combos inc cross chaining 50-42. Required just the cassette & a longer chain set up.
@sjjw43 Why would you not go 11-34 rear and 50-34 front? Same ultimate gear ratios but closer spacing and more usable gears - that’s how mine is set up (also 105 11 speed).
@@cmcockshootNot the same ratios. Looks like OP already has a 50/34 up front so their lowest gear is 34/42-much lower than one-to-one
Yes, it does shift into the 42 with no issues at all. I've got 50-34 front. I did have 11-34 rear & switch back with another wheelset I have when I wish. The adjustment is the appropriate length chain (clean & ready to go on) and adjustment of the B limit screw. There is a noticeable jump in some gears, but when heading up a 20%+ gradient on a long ride, it's a small niggle.
@sjjw43 I'm also running the 42t sprocket on and R7000 105 but I didn't upgrade the chain so I have to be careful not to cross chain or it does get very stuck (that was not a fun ride!). What length chain did you use and did it cause any issues on the shorter length combinations?
The low gear really is worth it for being able to climb as an irregular rider who often has luggage!
I'd definitely upgrade the chain. I got a 118 link & worked out the length by using one of the techniques where you bypass the derailleur. It can not remember how many links I removed, but it was probably about 3. I can cross chain without any issues, although that isn't my normal practice. I get no unusual noises & it shifts fine into the 42 when in the 50 on the front. I got the same issue you experience before changing the chain. All combinations work without any issues
5:47 I can just see the plastic portion of the small lever coming unglued with time!! Looks cool, but we'll see in the long run!
I have Ultegra 11spd di2 now but honestly my fav group of all time was when I got shimano 105 9spd in 1999. It shifted so sweetly and was the biggest upgrade that I have had ever. Only problem was the octa link bb seemed to be made of cheese and needed replacing fairly frequently
105 1999 was my first set. Switching the BB to a DA model fixed all the issues! Loved the yellow 105 text logo too.
External cables vs internal cables, wide chains and cog spacing vs narrow chains and tight cog spacing. In some respects, we've gone backwards with robustness.
I still have a bike with 9speed 105 from around 2000, took it for a short ride on the weekend after riding my new TCR 11speed 105, I think the 9speed shifts a little smoother too, my friends think I'm crazy to say that. lol
@@cup_and_conemodern, narrow chains are far more durable than old chains due to better metallurgy. Those same hardened steels could be used to make 8sp better but nobody is gonna pay $50 for an 8sp chain when they can get one for $15.
@@veganpotterthevegan My comment was strictly from a design point of view, the wider spacing meant greater tolerances for indexing. I agree chains then were terrible, though tooling and better standards were a big part. Shimano IG chains broke so easy, it's terrible. Then came HG, and Shimano bought a bunch of manufacturing tech from KMC which really accelerated their reliability.
excellent! Now 11 speed groupsets will be so much cheaper :)
11sp Tiagra will be coming soon. Possibly Tiagra di2. SRAM 11sp is already quite cheap
im hoping next year for tiagra 11spd, i want to buy a new bike next year with tiagra price@@veganpotterthevegan
@darinsteele7091 hopefully it comes out soon. My guess is that it'll basically be 105 11sp with less machining and cheaper aluminum which is totally fine!!! 8sp Tiagra was really terrible. 9 was OK and 10sp really is great for the money so I expect 11 will be even better. Older Tiagra felt very cheap but the 10sp stuff really doesn't feel much different than 10sp Ultegra did
I think our priority should be a lower price for the Shimano 105, rather than acquiring more gear. Additionally, there's a concern about subpar shifting performance due to the fully integrated internal cable routing handlebar."
Happy to see this mechanical option, especially for a cheaper peoples groupset.
Marketing bullshit - mechanical 15 speed is available for decades by using 3x5 without need to buy useless aluminium gears from shitmany .
Would have liked rim brakes still being supported, as I still have old bikes that are able to be upgraded... heck, I had to find a replacement front derailleur a couple weeks back, and it was super hard to find compatible components... ordered a microShift FD from overseas, because there wasn't anything in the LBS/local online shops
Yep. I totally agree. I also still have rim brakes. I just replaced my group set though so I hope I’ll be alright for another 10 years at least.
Can't you get the 11spd with rimbrakes anymore?
Can't you get the 11spd with rimbrakes anymore?
@@nicolasmattelin2374 yes but it is being discontinued on the 12 speed meaning it’ll be no more in the near future.
Just when I thought that I had built my recently purchased 2020 TCR the way that I wanted it, I now want this new 105 12 speed groupset...
I'm on a 10 year old bike with 23mm tires, 10 speed cassette and rim brakes and a frame that is too big for me. I can't wait to start seeing these on new bikes as I plan on upgrading the beginning of next year. Should be quite an upgrade with all these new features.
Happy with Shimano SORA ❤
Great to see this mechanical option is about. As a personal quirk of mine I like to know the power and cadence I'm rolling at in relation to the gear I'm seating in. I wish one day a small LED-like screen could be incorporated to the top of the hood indicating the gear I'm currently in. Unfortunately, being a wearer of prescription specs looking down to the rear cassette just doesn't work. As mentioned it's just a personal quirk, but if others feel the same that'd be good to know.
I have seen hoods with little needles to indicate the gear, but only in older and lower tier groupsets
Can't wait to get it!
ollie another great video mate
Always been a SRAM person but boy does this look good….love the gear ratios….climbing doesnt seem to get easier with age..dont know why!
we need a 12 speed mechanical, rimbrakes version hahaha
I am kinda shocked they let go of the rim-brake options so easily, while there is still demand. Recently a gazillion of 105 R7000 groupsets was sold out through Wiggle/CRC. Shimano/SRAM basically threw in the towel, and lost a market to the Chinese brands, which profit on those decisions.
Campagnolo is there for you, if only it was possible to find parts
Yes pleaseeee!
As someone who alnost always forgets to charge anything that needs to be charged I am glad there are still new mechanical groupsets!
Thanks Dr O...waxed chain ? Super nice bike , dude !
A note that 105 r7000 had all the same tech as Ultegra r8000: the shadow rear mech and the multi linkage front mech. A real shame they didn't update the look of shifters.
Not so sure the shifters looking the same is such a bad thing as they are always the most expensive part of the groupset and I'm willing to bet A right shifter, Rear mech', 12s cassette and chain is all you would need to upgrade R7020 105 to 12s. If the pull ratios are the same as 11 speed (like they did with latest Tiagra) you might not even need the RD.
@@chris1275ccthis is what I’ll be waiting to see and will be upgrading the rear of my road bike if that’s all it’ll take
@@skanetic I don't foresee any major issues doing it, the only sticking point could possibly be the Shimano 12s chain won't play nice with 11s rings but I ran a 12 speed YBN chain on 11 Ultegra for a while during the parts shortage with no issues, so there are always options.
Give us 105 mechanical with rim brakes! Please!
It is not a groups of the people if it's only a disk break option. For many people that means a completely new bike if they want a new 105, because their frames are prepared for rim breaks only.
Way to go Shimano!
I've had the 5800 series 105 for a bit and was used to it and pretty happy with it. When I changed to a 30 rather than 28 final cog, it was a nice extra (don't have a long cage for bigger cog). Since riding 105 di2 this year, the 34 at the rear is even nicer, but very much held in reserve, and not when I'm using the 50 up front. Clicky button shifting, and customising shifts is nice, but worry about the state of 3 batteries not so nice. Another little stress, in servicing, is the chain and quick link are thinner and the QL not recommended for reuse by the manufacturer, while the 11sp is a-ok in that regard.
Mechanical 11 sp.... I think you just need to keep less space set aside in your head for using it.
What about the weight of the battery when comparing the DI2 version to mechanical?
the battery is only 50 grams. the wiring is lighter than mechanical which almost offsets that. in general, depending on the groupset di2 is 100-200grams lighter than the mechanical version because of the lighter levers.
Di2 still lighter. Battery is 50g. He should have mentioned it though
Actually 67 grams with cables...
According to Shimano mechanical is very marginally heavier. We’re talking the weight of a Snickers bar though.
Luv it!!♥️
When Ollie mentioned to drink a brew (cup of coffee), I’m literally doing it right now at 02:30H while doing some research work for school and even upgrading my current bike 💯
Ollie is just funny. This content wouldn’t normally be funny, but he makes it so.
Getting very excited!! Wahooo!!
Mechanical 105 seems particularly ideal for the 'second' road bike, rain day bike, or that bike you're taking on a road trip and it absolutely has to work or be able to be fixed easily. Y'know, for those rides that you would really rather not use your number one road bike with Dura Ace and all that expensive stuff. Not that I have one of those.
Looks like a great idea.
Mechanical 105 making a comeback is great news! My number one bike absolutely has to work and be able to be fixed easily, otherwise it wouldn't be my number one. For us mere mortals DI2 is pointless, nothing more than a nice to have if you have extra money to burn. I'd rather spend that extra money on some sweet wheels anyway...
Best news ever!
Shimano has made the ultimate group set I hope I can keep my rim brakes and mix with older sets🎉🎉🎉
The Groupset of the People will live on forever!
Marketing bullshit - mechanical 15 speed is available for decades by using 3x5 without need to buy useless aluminium gears from shitmany .
Been on Dura Ace 7800 and many Tiagra/105 all I can say is that I don´t need anything better than Tiagra, the real groupset of the people.
Let's hope they will get back to rim brakes :)
I'm using this now on my gravel bike. From SRAM Apex1, I opted to switch to a 2x setup. Why didn't I get a GRX? Simple, the 105 R7100 has a better price point. It may not have the much needed additional cogs for climbing... just apply additional watts without blowing out your knees.
Hurray😃🙆 I can stick with my coveted 105 set AND I can buy that house now! 👍Happy days indeed 😊
I'm on 10 spd 105. I would love to try this new 12 speed!
Try 15 speed instead because of it is Marketing bullshit - mechanical 15 speed is available for decades by using 3x5 without need to buy useless aluminium gears from shitmany .
Nice Scott shoes 👟
Great to see more mechanical (I want something I can fix and maintain myself even out on rides) but is dura ace 9100 still the better option weight and function wise? Or maybe a mix of parts from the new 12 speed line up?
It should be great for cross training :) Nice video & Thanks :)
I'm glad Shimano is still developing mechanical groupsets. Hopefully they keep offering them for a long time rather than forcing us all to electronic.
Really keen to upgrade my 105 from 11-speed to 12-speed mechanical in the near future. Pretty sure to appreciate the 36T cog on the rear on the longer rides e.g. 24h Rad-am-Ring or very steep climbs you can find in the Eifel (my hood). In a nutshell: Get updated/upgraded for a reasonable price.
It's not just a comparison of mechanical vs. electronic, but the fact that the 105 Di2 12 speed is wireless from the handlebar. This is a big deal if you have a bike that has integrated hoses and cables, because it means that there is no mechanical impingement of the cable in a housing to worry about. So it is an important technology for frame builders who can eliminate holes and cable stops from the frames and make them stronger and more reliable as a result of a simplified manufacturing process.
I think this will also be an important product for the gravel market because of the electronic shifting and improved rotor clearance. They are competing with SRAM's wireless product at a very good price point, especially when it comes to replacement parts.
The other notable point in the mechanical rear derailleur is that the cable housing is very short, because the cable housing no longer moves. A very ingenious design allows the derailleur to articulate at the upper pivot point.
Hi Holly, first, hope you get a nomination for a golden globe 😅 super enterntaining video mate! Is the group of the people back? Depends a lot if OEMs will put it on bikes of the peopole. I wanted a new bike, but with 2k, you struggle to buy the most entry level carbon bike avaialbe. That is crazy.
Disk brake only? - still no longer the groupset of the people. Save the 105 rim brake!
Really nice bike 👍😍
Great review, but did you find those shoes you're wearing on a park bench?
amazing shot at 6:20 of the shifting
Definitely interested in this. I run mech Ultegra 11spd (52/36, 11-28) on my TT bike and mech 105/ultegra (50/34, 11-32) on my roadie. Probably swap out the TT bike first (rear only + new bar end shifter I'd imagine be fine) to get that extra 30 tooth cassette ring.
i hope they'll release the rim brake version as well
Don’t forget the battery, around 50 gms and 130 euros for you weenies. It’s a really nice addition to Shimano’s line, one that I might be tempted by when purchasing my next bike.
So, basicly if you have 11speed and want to uprade, you just need to upgrade your cassette and rear shifter leaver. thats nice
😂 super video, n lots of coffee trickled down!!!
Hallelujah!
I cant tell you how happy this made me. Now we need 105 mechanical with rim breaks and we are talking
I am glad to see 105 and GRX in mechanical 12 speed - electronic is all well and good - but not worth the cost imo
and the whole tactile feeling of shifting and riding is what I love about mechanical groupsets.
Shimano has seen the light!!!
Glad to see this video. I have two bikes with Ultegra. One mechanical and one electronic. Electronic is certainly cool. But mechanical works so well that I don’t really see an advantage.
Marketing bullshit - mechanical 15 speed is available for decades by using 3x5 without need to buy useless aluminium gears from shitmany .
4:03 “Better, because it’s 12 speed.” A wonderful marketing ploy that ramped up the price, whilst speeding up the wear of wafer-thin drive trains.
wow, that is progress ! 12 speed cassette . razors only have 5 blades. so much catching up to do.....
Need to hear about cable stretch and other tuning issues is regards to getting/keeping the shifting dialed in. I have to admit those shifters cut a “thick” profile. Need to wait until the price is fully released to understand the value over some of the other emerging Chinese hydro 12 speed options. But it’s certainly a step in the right direction!
It‘s more like trickle-over tech from MTB which has been 12 speed mechanical for years. I‘m curious if it needs less lever stroke for a gear change. That‘s where 11s road really felt outdated in comparison to 12s MTB.
It's not Shimano's first 12-speed mechanical groupset. That belongs to their XTR groupset. This is Shimano's first 12-speed road mechanical groupset or do you class as 24-speed to account for the 2x chainset?
I did notice that the barrel adjuster on the rear mech looks like it's about to fall out 😅for a big adjustment, adjust cable at the cable clamp and only use the barrel adjuster for fine tuning 👍
I'm hoping that Shimano will also release a rim brake version of 2x12 105....
great option for external cable routing and gear ratio choice. Boy this is gonna sell
I hope shimano also releases new and updated Tiagra and Sora.
I say get Dura Ace R9100 group set except for the lever where you can get the mechanical R7100 STI and chain, and R9200 11-28 cassette so you get the 16 tooth but still can fit up to 11-30. Microspline should be available too as an option so we get the 10 tooth cog instead of 16 tooth
About F'ing time!
Shadow derailleurs are cool.
I just installed the real groupset of the people - second hand parts. Constructed a SRAM Red 22 (2x11) setup with a Quarq powermeter 50/34, but my wheels aren't 12 speed friendly, so I was able to shoehorn an 11-32t Shimano cassette on the back (smallest I could find that would clear the 8/9/10 speed hub / spoke issue). Seems like groupset manufacturers don't seem to want me as a (high-end) customer because I still have rim brakes. Silly me, for spending money on useless bits like wheels and groupset rather than getting a new frame.
105 di2 rear derailleur should be about 302g + 50g battery = 352g vs 242g for mechanical
