Shimano Ultegra Di2 12 Speed Upgrade Project: Installation // Part II

[@mrwezbo]

Trick for viewers for hydro hoses without dropping $$$ on parktool stuff: leave existing hoses in, routed, not screwed it to callipers. Thread an old shift cable through the house until it's out both ends. Pull the hydro hose out over the shift cable. The shift cable will be left routed. Route the new hose in over the shift cable until it's through where you need it, pull the shift cable out, hose is now routed. Works a treat.

[@richardhaselwood9478]

There are much cheaper tools out these too. I've got one that is rebranded by several retailers

[@robbeelsas]

@@richardhaselwood9478 like Katana for example, it's the red anodized one that is sold by 10 different brands (such as Katana) and is all made by the same Chinese OEM

Really needed a good visual for this, thanks!

[@patrickprouty4415]

Great job. I just did this few days ago. My first di2 install. The new Ultegra shifters and derailleurs calipers and 165 mm crank set. Dura ace rotors cassette and chain. Not bad. I opted to run battery cables to the shifter to increase shifter battery life. Supposed to double it.

[@DaveCM]

Nice to know I'm not the only one who put deep wheels on a climbing frame. LOL! I was buying new wheels and for some reason went with the 60s rather than the 40s for my SuperSix. I got them and thought, "what have I done?" But, I actually like them. I've even done a lot of climbing and honestly haven't noticed a difference over the very shallow climbing wheels that came on it when doing a lot of climbing.

[@Hexsense]

Had SuperSix, but I alway use deep wheels (56mm and 65mm). They look fine, really. Eventually I found a deal on SystemSix and think, why not? So, I switch from SuperSix to SystemSix and now that deep wheels don't look so deep anymore next to the deep frame tube.

[@lolbubs11111]

Similar boat -- I run 50mm rims on a Look 785 Huez. Love it. Even the deep rims are 300-400g lighter than the aluminum rims that came stock.

[@jcsrst]

Love waxing the chain! Started doing it a year ago and haven't looked back. 5K on it with almost no wear😊 I just put DI2 on my Trek, love the new system, now it's easier to use the app without the additional dongle. I bought Ultegra and am very pleased with the ease of installation and performance.

[@mrwezbo]

Hey mate how many KMs do you get between a full pot wax? Do you use dripwax inbetween? I read you have to do a full wax every 500km or so, I ride around 400km/week and don't have time to do it once a week....

[@jcsrst]

@@mrwezbo I get 200 +/- miles. I don't use a drip wax in between. TBH i've never tried it. This method isn't for everyone. Somewhat time consuming and you ride a lot of miles.

[@glenmcfarlane]

How many kms is a great question. I hear different numbers 300-400 kms usually. I run multiple chains so I wax all in 1 go. Shane’s video was the first I saw letting the wax cool before removing it.

[@jcsrst]

@@glenmcfarlane I used to let the was cool but then the chain makes a massive flaky mess on the bike. I wipe it down as i remove it from the wax. The inner rollers and pins are what matters for the wax.

[@JustinDoesTriathlon]

Heyo Shane: Friendly little FYI re: 4:14 :When using a crowsfoot and a torque wrench, the crowsfoot has to be at 90degrees for the torque to be accurate.

[@gplama]

🙏🏼

[@richardhaselwood9478]

I'll be honest Lama, I'm most impressed you were able to get your hands one the pure unobtanium that is Ultegra 12 speed....

[@DanTuber]

Run the chain on a round pole/handle to fully loosen up the links before putting it on the bike. You also don't need to leave it in the pot while the wax cools off.

[@gplama]

Good tip! 👌🏼

[@SayMcGillicuddy]

came here to say this. If it's good enough for @Bikespeeds and all that. They dust the chain too, but admit it's an optional extra

[@eagerbob]

Another tip is to buy a few chains more (I use 4) and rotate between them instead of using drip wax. If you wax them all together, it is not much more work than waxing just one chain. Using a quicklink makes changing chains really easy, less then a minute work. By using the crockpot every time, you are sure that the wax goes *inside* the chainlinks, (unlike dripwax) where you want it.

[@bruceritchie7613]

Another wax tip - it tends to build up in the cassette - when you rotate chains just run a correctly size flat screwdriver between the cogs to remove the built up wax.

[@ayowser01]

I always assumed the wax needed to cool down before removing the chain from the crock pot... 🤔

[@bradallen8643]

Brilliant as usual Shane. So easy to follow and pumped that you are hot waxing now (no more dirty chains)

[@billmartin1010]

I was a Di2 early adopter all those years ago. I've been riding it for a lot of years. But I have to confess that I don't see the semi-wireless Di2 as an upgrade. The shifting with fully wired 11-speed is more immediate and is always there. I despise that semi-wired is asleep sometimes when I want it to be awake. I understand why it happens . . . but I like fully wired better.

[@LainOTN]

I ended wiring my 12s di2, that was one of the main reasons, instant wake up. The others, 50% more battery range, no need to change coin cells. You can still pair it wireless so in the event of a cable disconnection it will kick in if you have a coin cell installed.

[@DaveCM]

Wait! I didn't realize it had to be "woke up". Sorry. My bikes have SRAM and there is no waking it up. It just always works. I didn't realize Shimano decided to go that route. I guess to extend battery life.

[@LainOTN]

@@DaveCM My experience is that AXS also sleeps but is much less conservative, minimum movement will wake up the system. Seems that Shimano is being too conservative.

[@BetterShifting]

@@LainOTN Sir Lama told me that SRAM put accelerometers in the system, which is also why they recommend removing the batteries when you travel with the bike. Shimano didn't put accelerometers in these levers :)

[@LainOTN]

At time 8:25 in the video - is that 52/36 Dura Ace or bigger.. like 54/40 ? The chain-rings look bigger than 52/36, but ultegra 12 speed only take 52/36... you need Dura Ace for 54/40 (Dura Ace Front Derailer for 54/40)

One huge advantage to DI2 that has made it possible for me to upgrade to a Modern road bike is the synchro shift feature. With limited use of my right forearm I could not use traditional paddle shifters. With Synco shift programmed to use just the left paddles to shift and brake I’m able to ride a great bike. I have tried to write Shimano to thank them for that feature but could not find a contact method on there website. Please pass this on if have a contact at Shimano. Thanks

[@obikedog]

Sorta raced passed it but to install a brake line you will need an "olive" to clamp it to the lever. You might re-use them but I'd probably not recommend it. So for setting up a new frameset it will be necessary, as I found, to purchase new "olives" for the brake line installation. Remarkably, the $600+ Dura-Ace shifter/caliper combos I purchased don't include this $1.50 part. (They did through in a single barb each. Awfully nice of Shimano there.)

[@glenmcfarlane]

Great video and love your work Shane. The dancing when shaking the bottles gave me a laugh. I’m looking at my 2019 TCR differently. I still love the bike, but that upgrade cost more than I paid for the bike! Plus I’m handy, but not as handy as you when it comes to being a bike mechanic. Maybe time to talk to my local shop here in Singapore.

[@energylab6277]

Tip for tuning with a stiff waxed train without riding on it. Run the chain slowly with a hair dryer focused on the rear hanger, which is where the chain bends the most. After 2 minutes it will be good to tune, and no rough riding on your next ride initially

[@giusepperaucci5883]

Hi Shane. I watched your video only few minutes ago. I saw you setting the battery of your new Ultegra group and I have a question for you. Please let me know if the 2 cables for connecting the battery can be put into the connectors of the battery regardless of positive and negative or there is a specific way to set them. Thank you so much for your instruction. However, very nice and interesting video. Pino. Rome.

[@gplama]

Di2 batteries don’t have the standard positive/negative terminals. The cables just plug into it. The only limit with the newer batteries is that I believe something has to be plugged into the center port. Be it a cable or dummy plug. I can’t recall the exact specifics.

I’ve never been able to get the rear brake hose in the anti-rattle foam tube without first taking the headset apart and running it down the brake hose - then routing the brake hose up the correct ports to the handlebars. If you have rattling, check for the rear brake hose hitting the down tube from inside. Also check out hexagon Boron Nitride powder (hBN) as an additive for your waxing; my experience is it last 2-3x longer than PTFE as hBN is one of the best inert dry lubricants easily 500 mile intervals between re-waxing and hearing just the hum of the tires is awesome.
