You should replace JC200 with WU111
Scott Foil
Shimano 9150
Shimano FCR-9100-P
Shimano C60 tubulars

Is it possible to connect the rs-910 to the left shift?

Re JC200 and hiding it.. just don't use it it's a waist of timeZ a properly wired up set of bars has a long main cable 12-1400mm from the lower junction a 650mm between the shifters and a 550mm to your rs-910 if you wan to use a wu111 or the older version( cut off the rubber band tabs first ) add a 150mm etube wire to your rs-910 and tuck it into the bar end.. adding the jc200nand using the silly Y wire is asking for trouble. Simple is best, once apoin a time Di2 was hands down the most reliable GS on the market.. that's just not the case any more and shimano throwing more 'bits and bobs' into the system isn't doing anything to reverse the situation

This thread has been helpful to me so I figured I'd sign up to share what I just discovered.

Also called Easton, as my LBS has not had success passing through on my EC70 Aero bars. Easton rep gave a half-baked answer that they have been able to do it on some but on others the resin creates too much blockage. Bike shop is going to give one more college try. We'll see I guess.. :noidea:

Otherwise I'm ditching the aero thing and going back to my trusty Ergonova Team... :evil:

Despite dak's earlier findings Felt's 2018 AR FRD and AR2 use Easton's EC90 and EC70 Aero bars respectively, coupled with the RS910 bar end junction. I'm reaching out to Easton to find out what's what.

So here's what with thew Easton aero bars.

"The bars are built in three pieces that are bonded together. Because there was originally no reason to run a cable through the bars we didn’t clean excess resins from the inside which means some may have a thin wall blocking the cable. On all new production runs we have added a step to ensure the bar is free of blockage but it’s a 50 / 50 shot with the ones that are in shops now."

I haven't been able to find any local Easton retailers yet. Might order a few from different high turnover online shops and try my luck.
