Beginner Tries to Install Ultegra Di2 12-Speed

What do you get when you give an inexperienced home bike mechanic a brand new Shimano Ultegra 8100 Di2 12-speed groupset? You get a mess.
Huge thanks to ‪@ridesofjapan‬ for his incredible videos, which gave me the confidence to try this. If you wanna watch a competent person install a groupset, here’s his Dura Ace video: • Dura Ace 9270 12 speed...

Excellent work! Soon you’ll be rebuilding bikes just for fun on the weekend ;) Also 60grams, definitely worth it ✊ And cheers for the plug!

[@MitchBoyer]

Haha now I’ll always remember my first 60grams 🥲

[@Jacob99174]

He was able to achieve the 60 gram savings once he removed the 2nd derailleur LINK that was left on 😂😂😂😂

[@GuidoGabriele]

It’s weird how the first time doing this seems so intimidating, but then you realize it’s all just screws and 90% of the bike can be assembled with one Allen key.

[@user-mg8lx8ht8f]

no its weird how scary it is until its perfect even though everything is going perfectly well you are scared 100 precent of the time and for many rides after any problem will cause fear

[@SaschaRissling]

Dude you really know how to do this youtube thing extremely well. I'm only 34 seconds in so i cant say anything about the video. Just wanted to tell you i'm a fan. All the best from germany

[@MitchBoyer]

Thanks for watching!

[@EditioCastigata]

Before removing your old group and installing the new 12s: Just remove the front derailler and install the new (tape the battery to the top tube and so on). Check whether it's able to shift (leave the chain in the middle at the back) reliably into the lower ring. The new 12s group is designed around a 1mm outboard setup and your frame could be outside tolerance. Most of the time you can work with a 1mm spacer (both sides of the crank!), but sometimes it doesn't work out and it would suck to reinstall everything.

[@h1n1worm]

Not having a speed link is kind of weird. The only real difficulty in doing things like upgrades, changes, and heavy maintenance is the tools (how often do you need a cable cutter or press-fit removal tool?). But once you have them, it's such a pleasure to work on your bike

[@samuelcarter8021]

I didn’t realize you’d have to remove the bottom bracket to fish the wires through. Tough job!!! You did awesome for a first time, it’s not as intimidating as I thought it would be.

[@llgmota]

You are CRAZY and courageous… I would never try this at home, but I enjoyed every sec of your painful experience. Great video!

[@MitchBoyer]

Haha thanks Luiz!

[@FordChristmas]

Hi A tip! When removing the wires and breakcables, when everything else is removed, I always attache the old ones to the new ones with tape, barbwire(a string of steel wire fits breakcables perfect and hold them together!). Then pull every old out together with routing the new through the frame. That way you dont have to try rute it afterwards. 👌🏼

[@CamNicholls]

Well done on persevering mate. I would have given up at minute one 😂

[@MitchBoyer]

Haha thanks Cam! There were definitely moments that had me questioning my sanity 😅

[@endatheworld]

[@LukeRichardson1981]

Nice. I just did the same thing on my road bike this week - though I was changing from R8000 Ultegra with mechanical disks to 105 Di2 with hydraulic brakes. I was actually most worried about bleeding the hydraulic brakes, but despite having to cut the hoses to fit, the brakes worked without any sponginess right from the start - guess I was careful enough that I lost almost no brake fluid. With respect to the time issue, from my experience working against the clock basically never goes well. It always takes me quite a bit longer to do any work than I'd originally thought it would - and seemingly minor issues like your FD alignment problem are almost always the culprit for eating up huge amounts of time. Love my Di2 setup too, and can't wait to get out and get some real kms on it.

[@Jacob99174]

Feels incredibly accomplishing, doesn’t it!? 🎉

[@kevinhawker2946]

Chapeau to you‼️ I’d never set a deadline like that (would remind me too much of writing a late-night term-paper due the next day!!!). I’m building a Dura-Ace version; wish me luck‼️🙏‼️

[@ranlo.justin]

I'm a bit late to the party but thats such an awesome feat! I started taking apart and building my bikes around the same time you posted this video and I know exactly how you feel!! Scheduling a bike build into a tight full-time employed schedule and also getting all the right parts/tools is stressful enough in itself!!

[@RobertBeckk]

I love how you quote something, and my mind goes to the clip and then suddenly it cuts to the clip. very satisfying.

[@MrLaddog]

Awesome job Mitch! I had a similar FD issue. I added a crank based power meter and well let’s just say after several hours I broke down and gave my LBS $10 to fix it! Well worth it though.

[@MitchBoyer]

I feel your pain! Do you know what they did?

[@mvp_kryptonite]

Same happened to me, changing a gossamer to 105 4iiii left. My LBS slightly moved the rotation of the front mech and a tweak to the tension and that was it. Funnily enough I took off the left side last Saturday and put it on my newer bike but with tiagra and didn’t want more hours fiddling to get it to shift to the top ring so that’s this weeks task. Amazing what a tiny difference in Q factor does (left crank is on so it can’t be anything else surely lol)

[@MrLaddog]

Yeah I am very friendly with a few of the guys there so they walked me through a few things while they fixed it. It was really helpful since I think I may be attempting a DI2 drivetrain upgrade myself soon.

[@MitchBoyer]

@@MrLaddog Good luck!

its the troubleshooting that usually takes time, effort and mental strength and im glad you held on and got it all fixed by yourself 👍

Some day i'll hope trying to do a full maintenance of my bike for myself, disassembly everything... i'll take the risk like you do with this epic video! BRAVO! PD. And the new Ultegra is simply awesome...

[@MitchBoyer]

Thanks for watching Diego! Send me the video if you do an epic build one day!

[@TheKampklovn]

Awesome video! Two questions, did you not have to bleed the brakes, and are that the ENVE Aero road handlebar? If so, how do you like them? Considering getting them myself.

[@MitchBoyer]

Love the ENVE Aero handlebars-super stiff and comfortable too! The brake caliber and cable comes prefilled with brake fluid, and the reservoir in the shifters is prefilled too. As long as you don’t lose any mineral oil during the install, they’re good to go out of the box. I lost a bit too much oil while installing the front brake and did need to bleed it a little bit. The rear brake was tight right off the bat, no bleeding necessary.

[@BayouJosh]

You are the Man!!! Brave Man! I just made the same upgrade on My Specialized Roubaix. I paid a pro to do it though. Definitely worth it.

[@MitchBoyer]

Thanks for watching, dude!

[@lazyrider6918]

Super impressed that you tackled this on your own without any prior experience. HOWEVER, I think you feeling it was "worth" the upgrade is more about confirmation bias than objective reality. Price and weight savings, this switch to Di2 is not worth it. As far as shifting and performance, still not worth it. I have mechanical Ultegra and Di2 as well and as someone who has been riding for 35+ years, I can say that Di2 is "NIce but unnecessary". It is simply the difference between "wants and needs" and you did not "need" to spend $2500 as it will not make any difference in how fast or far you can pedal that bike.

[@MitchBoyer]

Thanks! Your opinion is totally fair and valid. I’m not racing or aiming for a world record, so to me it’s not really about performance. I’m just a dude who enjoys riding his bike. Whether it’s confirmation bias or not, I like the way it feels and sounds when it shifts. It brings a little smile to my face. Do I need it? No of course not. Do I enjoy it? 1000% yes. Will it get old one day and become normal? Also 1000% yes. ¯\_(ツ)_/¯ it is what it is. Your description is spot on. Its “nice but unnecessary,” just like the rest of my bike :)

[@marcusvaldes]

I don't know man. Have you ridden Di2? I've had Ultegra mechanical on past bikes and this is NEXT LEVEL NICE. Plus the buttons on the hoods underneath the tape to cycle through pages on your Garmin Edge--how cool is that??!! I'm sold.

You are a brave, brave man to do it yourself. At least ultegra di2 disc has no cables for the shifters, just the brakes. Did the brakes require bleeding?

[@MitchBoyer]

Thanks, James! Having only brake cables to route through the handlebars made it so much easier. The brakes came pre-liked with mineral oil so as long as you don’t lose a bunch during the install they’re good to go without a bleed. Of course, I lost a bunch of mineral oil while installing the front brake so I still needed to bleed that one 😅

[@uptown710]

I’m actually buying parts for a new bike now. I would LOVE to DIY my build, but I’m lacking in the tools department. It also sucks that the shops charge $200-$350 to build 🤯

[@LukeZhang1]

That was much smoother than I thought. You could’ve saved some time by not sleeping… jokes aside, the only big time saving potential was just to use your old cables to route your new ones, would’ve saved half an hour

[@MitchBoyer]

Haha, thanks Luke!

[@Tantewillieja]

Why did you install new brake calipers? They are the same aren't they?

[@LukeZhang1]

no the new 12 speed has new brakes, which have larger gaps to prevent rotor rub. it's the best part of the 12 speed upgrade

[@diegorobayo]

Hi, they are not the same... The ports are a little different and the more important thing, the new calipers have more clearance for, in theory, avoid some noise issues with the discs... at least for me, they're working very well right now, 0 noises. Chears

[@MitchBoyer]

Thanks for watching dude! In addition to to the functionality improvements Luke and Diego mentioned here, the calipers came with the set and were pre-filled with mineral oil. My old brake lines were already too short. I’d have to install new brake lines, so installing the new calibers was actually easier (and less messy) than trying to install new brake lines to the old calipers. And I’m lazy so I’ll always take the easier route 😅

[@Tantewillieja]

Ah cool, thanks!

Hi! To be honest, it got pushed back a bunch of times due to getting covid, my honeymoon, and the steepest streets videos. It'll be up mid-January, though! I can give you the quick version now: I still love it. The magic has worn off a bit, and it almost feels normal, but I still really appreciate it when shifting under load--going up hill or in a sprint.

[@AkashKandarkar]

Everytime I look at my bike "The bike is good, but it can be better"

[@Stevenafoe]

Is your dog a dachshound? Love those! (And love the upgrade also, lol). Thx for showing. How did you connect the battery to the derailleurs? Did you need to drill a hole in the frame or could you use an existing one?

[@MitchBoyer]

Yep! She’s 12 years old now. Cant believe how fast time flies 😅 The bike already had all the necessary holes but I did buy proprietary a di2 battery cover for my frame from BMC. I’m definitely not qualified to drill into any bike frame. That’s a job for the pros haha

Hey mate this video was very informative, thank you! Definitely gives me the confidence to have a go myself. I was just wondering, is it necessary to replace the bottom bracket moving from 11 to 12 speed ultegra? I can see you changed yours, but I was under the impression this isnt necessary.

[@downinla4076]

The Shimano BB are the same for 9 speed - 12 speed cranksets. However, Shimano does state that once a press fit BB is hammered out, it should not be re-used. Personally, I have re-installed my PF BB a few times and I did not notice any performance loss or creaks.

[@LukeRichardson1981]

@@downinla4076 Just another reason to dislike press fit BBs. For me, they'd be a dealbreaker - I'd absolutely refuse to buy a bike or frame without a threaded BB.

[@tonyh1859]

You installed a new bottom bracket, was it necessary? Or you could just put the old one back?

[@Willyw0nka1]

In the end how did you work around the front derailleur? My frame also doesn't allow me to install the derailleur in spec according to the diagram.

[@seanhwy9761]

Why did you change the crankset set and BB? It was already ultegra. Even if you just wanted the new crankset your old BB would have worked unless it was creaking or something. Maybe you already touched on that and I just missed it.

[@MitchBoyer]

I changed from a 50/34 to a 52/32 crankset because I wanted a little more at the top range for my sprint! I switched out the BB because I was switching everything else out, and I thought it'd be nice to have the bike feel brand new again :)

[@davidk5307]

Any advice or maybe a good video topic. How do you know which components or drive system might be compatible with your current bike?

[@MitchBoyer]

Great idea. Unfortunately, I'm totally not qualified for it, lol. I upgraded from Ultegra to Ultegra, so I knew there was a pretty good chance it would be compatible. bettershifting.com/ is a really good resource if you're in the Shimano ecosystem.

[@yonglingng5640]

Let's take the bottom bracket for example. To know which one fits, you need to identify two things: your frame's BB standard and your crankset spindle's diameter. In his case, his BMC is on BB86 and Shimano Hollowtech II cranksets use a 24 mm spindle, so his new BB needs to be a BB86 made for 24 mm spindles, commonly labeled as "for Shimano".

[@michprent]

wow, you did not have problems with bleeding the system? i tried it so many times, and i finaly know how to do it, after 5 fails

[@MitchBoyer]

The brakes come pre-filled with mineral oil so they don’t need a bleed, unless you spill a bunch of fluid during the install. So of course I spilled a bunch of fluid during the install 🤪-just with the front brake. Bleeding it wasn’t too bad, since the lines already had a bunch of fluid. And the rear brake didn’t need a bleed at all! Brakes feel nice and tight. I feel your pain, though, I bled my old brakes a few times and it was always super difficult, especially the first time.

[@JaiJai-by4tp]

Did you use the grub screw to adjust the toe in/out that butts to the frame .

[@MitchBoyer]

Yep. The issue is that the front mount forces rear of the derailleur pushes too far out from the frame even when it’s in the position most near to the frame. Not sure if it is a bent mount-it doesn’t look that way. Luckily di2 allows for a ton of adjustment and I finally found an adjustment setting that works

[@patriziaprost9001]

I am even scared to (slightly) modify the dealer's setup when I bought the bike.

Hi Mitch! Did you have to buy a new cassette for your trainer as well when you upgraded to the Di2?

[@MitchBoyer]

Yep. I put a new Ultegra 11-34 cassette on the trainer. Unfortunately the 105 12 speed isn’t available yet. I would rather have used that since there’s no need for the lighter weight on the trainer.

What did you end up doing for the FD? For the life of me I can’t get it sorted. The hanger makes it next to impossible for me to fasten it at the angles needed to trim electronically

[@EditioCastigata]

I'm not the OP, but you can file the washer.

[@marcusvaldes]

What was the issue with the front derailleur? How did you correct it? I have the exact same frame except fortunately mine came with Di2!! You need to come up to Atlanta in the spring and ride some HILLS/MOUNTAINS! Look up the ASSAULT on MARION or The ASSAULT on Mt. Mitchell. I'm doing the Marion one in May. It's going to be epic!

[@MitchBoyer]

Nice! I think the braze on (I think that’s what it’s called)/connector on my frame is a bit askew so the front derailleur has an extremely narrow range where it’ll work without rubbing. I ended up taking it all off and tweaking it a few times before I finally got it dialed in. And of course, it could’ve been user error 🤷 I’m on the east coast a few times a year to visit family. Might need to tack on a trip to Atlanta sometime!

When you mounted the front deraileur did you install the little silver metal tab with the adhesive on one side? I bought my bike from a shop and it is missing! Now I'm a bit nervous to remove it and install.

[@MitchBoyer]

Hi Marcus! First off, just a reminder that I'm not a mechanic, lol, but from what I understand, the tab is used to set the derailleur, and then it's not neeeded anymore. (It protects the carbon frame from a screw used in the installation). A lot of people will remove it after the initial installation process.

[@marcusvaldes]

@@MitchBoyer I think we may be discussing different tabs. The one I'm talking about is between the frame and the derailleur so you wouldn't be able to access it after you mount it. It's basically a surface for the 2mm adjustment screw to torque into so to speak. I did talk with a mechanic friend and he said that most bike manafacturers are reinforcing that part of the bike and not to worry about it!

@@marcusvaldes yep, same tab :) I pealed it off the bike it of with a pick afterwards. Nice to hear most manufacturers are reinforcing that bit of the bike!

Hei, What gear ratio are you running? Any chain vibrating? I'm having 50-34/11-34 and on the smallest 3 spokes my chain goes crazy vibrating - in a sprint my feet's go numb.

[@MitchBoyer]

Oh man that doesn’t sound good. I’m running 52-36/11-34. I haven’t gotten any chain rubbing, but I do get a clicking sound on the 5th cog sometimes, almost like it’s indexed incorrectly. I’ve tried re indexing and it persists. ¯\_(ツ)_/¯ everything else is whisper quiet and I don’t get any vibrations.

@@MitchBoyer lucky you! enjoy it! :)

Hi, did you end up changing the front derailleur hanger?

[@MitchBoyer]

Hi! I messed around with it for an afternoon and finally got it into a position where it worked.

[@conrad6226]

Honestly impressive as fuck.

[@aandres87]

idk if it is toolate but did you sell your old ultegra groupset?

[@MitchBoyer]

I put it on my wife's bike :)

[@egutzait]

Curious why you went Shimano Di2 vs SRAM ETAP?

[@MitchBoyer]

no real reason, I just like shimano 🙃

[@GrouEEf]

You could've justleft the cranks and BB in- 12 speed Di2 cranks are compatible with 11 speed and vice versa. 🙈

[@MitchBoyer]

True! I switched because the new cranks are 52-36 and my old ones were 50-34 and I wanted the extra potential 💪 also I went with a shorter crank length (170mm). Just didn’t put it in the video 😜

[@EditioCastigata]

New cranks have 44.5mm, old 43.5mm chainline. That affects whether you can setup the FD to properly shift to lower gears.

[@mvp_kryptonite]

Haha nice video. No torque wrench to give her the final touch?

[@MitchBoyer]

Thanks for watching! You can spot the torque wrench in a few shots, but I didn't make a point to feature it! hopefully It doesn't give anyone any bad ideas 😬
