I'm finally getting out on my IA10 and had a couple questions. First off, is it typical that the wiring coming out of the back of the aero bars is pretty tight? I can only turn about 45 degrees before the wires are taught. Granted, out on a race course I'm not likely to be making turns that require me to turn more than that, but I'm concerned about the strain on the wires over time. My bike shop said that it is an issue with the Di2 wires provided...they just don't provide enough wire to give adequate play in the wires.
I also wanted to charge the battery this evening for the first time but found that upon unscrewing the little cap under the bars on the front end of the frame, that the cap seems to be attached on the inside to something and everything is tightly packed in there. I did not want to risk breaking something by forcing anything in trying to pull stuff out. What should I expect, or is there something I'm missing? What is the easiest way to charge this thing?
There is a 2nd Junction B JC41 unit and 1 extra wire needed to relocate the Junction A box with plenty of slack on bar set-ups with risers.
The Di2 wires are hard-wired into the brifters and extension buttons, this is not a Felt issue, it's a Shimano issue. They've identified this and future versions of their shifters will have a longer wire on the integrated harness but Felt wasn't going to wait. You'll need the 2nd JC41+ 1 extra wire to connect it to the Junction A in the nosecone (except for XS size).
The cap is connected to the Junction A which is connected to the aforementioned tight wires. You've likely not enough slack to pull it out all the way. You only need access to the small port on the side to plug in the USB cord.
Your bike shop should eagerly walk you through all this as part of a $5000+ transaction; where did you buy the bike?
Let me know if you have further questions.
