Just in from an evening fettle. The Di2 bits started arriving today, in fact far more than I expected hence the late night
The only parts outstanding are the frame grommet kit, the RH lever (it was cheaper to buy them seperately for some unknown reason and they came from different suppliers
) new bar tape and the bar end junction box.
I started by stripping down the bars and fitting the LH lever. I left the old RH lever in place to use as a reference so I dont have much adjustment to do when it's al back together. I drilled two small oval holes and removed all burrs, one 40mm in from each end of the bars. I then fed the old inner gear cable through the bars to fish the first eTube wire through; you can just about make it out in the image below, with the wire coming out of the drilled hole on the LH of the bars and out of the end of the bars on the RH side. This cable connects to the LH shifter and will connect to the bar end junction box on the right when it arrives.
Once connected I taped the wires and brake hose to the bars ready for bar tape, leaving a little slack in case the lever needs moving slightly.
Next is the WU-111 bluetooth module - I don't think I could have got it any closer to the GPS mount if I'd tried
I read somewhere about putting cable ties around the wire that goes through the downtube to prevent it knocking whilst riding - I used this technique on the Bianchi when I installed Di2 earlier in the year and it seems to have worked a treat so repeated it this time also. I couldn't get the cable ties through the hole at the top so ended up fishing the inner gear cable through and pulling the wire up from the bottom, cable ties and all
Where there's a will there's a way
With the downtube wire in I fitted the junction box at the BB end and quite quickly had the remaining wires threaded through for the battery and mechs.
With the junction box wrapped in bubble wrap and poked back up the seat tube I refitted the BB then fitted the new Di2 mechs.
Nothing more I could do without the outstanding parts so it was wheels back on and put the bike to bed for the evening, locked back up on the wall. I've got the battery fitted in the seatpost, you can just see it between the seat and chainstays on the bench in the pic below. I haven't fitted it because I don't want to energise the system before its got all the bits connected; no idea if it would do any harm but I'd be annoyed if it did
I don't think any bits are due tomorrow but I could bleed the rear brake if nothing else
