How To Adjust Shimano Di2 Front Derailleurs




What do you think about this video?

Art's Cyclery: @Ken Sato: Sounds like you have a chain line problem, which means that tweaking the Di2 setup won't help (I'm assuming your have your low limit as tight to the chain as possible in the lowest gear). You need to either move the cassette outboard (e.g. using a different wheel where the cassette sits further outboard) or move the chainrings/driveside crank arm inboard. If you have a BB30 crank, that could be your best option. With other crank standards, it's tough.

Glen Knight: I've just finished building my second bike with Di2 gearing on it. For some reason I cannot get the indexing right on this one. when adjusting using the e-tube software it goes right down to 14 before its in the correct gear. This doesn't allow for a smooth gear change throughout the range. To remove all the noise and get a good gear change I need to push the bike moves to gear 4 but the e-tube software still reports gear 5. This of course prevents me from moving in to gear 11 once I complete the setup.Any ideas how to resolve this?

Caleb Uy: Where should the rear derailleur be (gear) when doing the front derailleur? because i noticed that the front derailleur auto trims/adjusts when the rear derailleur is shifted to the lowest gear or highest gear. im using dura-ace 9070.

P T Withington: Great vids! Question: I replaced the Shimano 54-42 standard crank with a Quark/SRAM compact crank on my Di2 (50-34). When in the small chain ring and shifting to the outer cogs, the chain rubs against the derailleur cage. I've checked the spacing and alignment per your video, but no improvement. Seems like the cage may just not be long enough. Is the cage just the wrong shape for the compact crank? Any suggestions?

Dan Lustig: After running the Ultegra Di2 for almost two years the chain dropped twice today. I was in high gear. Small chain ring and 2nd and 3rd from the smallest cog. Once putting the chain back in place I am hearing an unusual click when riding in most gears. Also when in the smallest cog the chain rubs against the inside of the inside of the crank. I've been told by my LBS that its normal. I would appreciate some advise.

EngineerByDay: For some reason my 6870 di2 is getting chain rub when I'm in the 4 ring from top in the back and big chainring in the front. Advice for this problem?

dr.Muscles: Hi, again, quality instructions. I myself a ride ultegra 6870di set up (on two bikes, one Specialized Venge and a Canyon Speedmax CF). Both bikes have the same strange issue, which my lbs could not resolve (they are terrible though). With my chain on the biggest front cog, the drivetrain starts to make a grinding noise when the chain is on the 5th smallest cog in the rear. This noise becomes increasingly louder if I shift to the 4th and 3th smallest cog. The drivetrain runs smooth agains if I shift further to the 2nd and smallest cog. The gearing seem to be perfectly adjusted, shifting smoothly both in the front and in the back (I adjusted it multiple times on the fly, but finetuning does not eliminate the grinding noise). I took both bikes to the mechanic after which the issues occurred. On the tri bike, a full ultegra 6870 set up was installed already, but the mechanic just changed the crankset to a 172.5mm crank arm. On the specialized venge, there was an FSA crank installed and a normal 10-speed mechanical ultegra drive train. There, the whole setup was exchanged for a ultegra 6870di. I'm puzzled. EDIT: I think I managed to identify the issue: the front derailleur can not be adjusted downward (which was necessary due to a switch from a double to compact), because of limited adjustment possibilities (canyon speedmax cf users, beware!). Now, with a little bit a tweaking and "suboptimal" adjustment (adjust upperlimit screw of front derailleur a bit as to move the front derailleur a bit more outward that what is advised - I still need to take it for a spin to see whether the chain is kept on the drive train), I managed to reduce the friction between the chain and front derailleur. Things are still not running entirely smoothly tho. Is there a solution for this issue? Ie, how can I modify the installation so that I can bring the derailleur another 3-5mm down?

Barbara Arnold: Really great video. Thank you! Really helped me understand why my Di2 was having shifting/dropped chain issues. Problems?---solved!!

Brent Mcdonald: Thank you for this perfectly done video. It solved my problem. I applaude how you kept it nice and short.

Ken Sato: I have a 6870 setup (front 52X36, rear 11-32 with GS cage) works great except I get some light chain rub on the front derailleur when I am in the middle sprockets of the cassette. Doesn't look like there is anyway to adjust the auto-trim of the front derailleur when using the E-tube project software.

Gi tri: I have an issue on my small to big ring shifting. I recently switch from Shimano 6750 to a Rotor 3D crank w/ BOR chainrings. When I shifted from small to big w/ the Shimano, it worked flawlessly. Now, it takes about 2 revolutions for the big chainring to "pick up" the chain. It causes the chain to rub against the BB shell and it's not a good sound at all. What gives? Solution? Thanks!
