Any Tips on Installing Di2

[Justin S]

Just bought the 10sp Ultegra system and will be internal cable fitting to my bike this week. But has anyone done it ? Just wondering how easy or tricky it may be. Hoping it wont be too tricky.

There are a few videos on You Tube that show you how to do it. Use the cable tie method to stop the cables rattling inside the frame, just make sure the ties are braced around the inside of the down tube.

I converted my bike to To Ultegra Di2 (internal wiring) and more recently I installed another Di2 groupset to my girlfriends bike(mixture of internal and external wiring) without any major problems.

As already said, use cable ties to stop the cabling rattling inside the frame. I also found it much easier to strip the whole bike before fitting the cabling. This was the bit that took me the most time. Tuning and setting up the gears is relatively easy.

I used this guide here: http://techdocs.shimano.com/media/techdocs/content...

Line the rear derailleur gears up by hand with the chain off - I used a metal ruler to get them absolutely perfect.

Other than that - its easy-peasy

Cool stuff. Just had confirmation from Merlin of order completion, so looking forward to their arrival Tuesday. Will strip my 105 off tonight ready. Cant wait to try it out.

Well, got everything today. Got home, spread it over the dining room table. Had already stripped my bike down last night. No instructions for it included. Found I had many bits I never used ( hope I don't need it) Had a few issues with the front mech, but sussed it in the end. Had 2 front loom kits in the box, which confused me again. Different part numbers too. One was in the bag for the rear mech and the other was in a bag on its own. Decided to try the one with the mech. Had issues fitting the connector under the bottom bracket and had a file a little out the frame to be able to slot it home. Other than that and fiddling cables into the frame, it fired into life ( charged the battery at work so was fully charged). Found afterwards the front mech grub screw to locate and support the front mech on Park Tools site. So checked and adjusted.
Shifting now changed in my eyes is a revelation. So much smoother and precision than the 105 I took off. Up the road in the darkness test, was great. Really looking forward to testing it at the weekend.
