New replacement parts arrived today so I got stuck in to the upgrade to R8050 Di2 Ultegra from 6800 Ultegra.
First off with the old derailleurs but I left the inner cables in the frame in case I needed fish wires.
Cranks off and BB removed to get access to the frame. The BB area will house the tiny B junction box.
Handlebar tape off, brake cables out except the inner to the rear as it would be a fish wire for its replacement.
New shifters fitted but left brake cables till last.
Rear derailleur mounted, as normal. Couldn't mount the front derailleur as I'm waiting on a band on braze on mount, which is due tomorrow.
I removed the Di2 bungs that were fitted in the frame and started to thread the wires through the frame. Concealed are the rear derailleur wire, front derailleur wire, battery wire from the seat post and the wire from the front junction box A/ controller to the BB at J Box B. Expecting difficulty and hours of faff, I had the wires in the frame in about 10 minutes. Happy days.
Connecting it up is another 2 minute job. J Box B was safely tucked into the down tube after being wrapped in a bit of pipe insulation against rattles.
BB and cranks reinstalled as normal.
Rear derailleur connected, shifters connected, front derailleur connected and hung temporarily with a cable tie.
Next on to handlebars where I taped the shifter wires into position pending the final new bar tape wrap.
Brakes were next. Front new inner and outer were supplied so installed. I used a tiny piece of heat shrink to connect old to new and successfully fished the new rear cable to the rear brake, and managed not to forget the routing anywhere 🙂. These were connected and trimmed.
All that remained at this point was to fully mount J Box A properly on the little supplied bracket, refit the saddle post and rewrap the bars.
Having already charged the battery it was easy to test movement in the derailleurs, as it really is just plug and play. All tested and basic mechanical setup done with limit screws. Chain refitted and then a tidy up.
Until I get the front mount tomorrow I can't fully finish but I'll get a few pictures done then of the finished article.
Looking forward to a spin tomorrow. 😊
