Since yesterday I'm the proud owner of a new Giant Trinity Advanced TT frame, and I'm now going through the business of making up my mind about di2 wiring. The frame allows for full internal wiring, but I don't (yet) know how to easily expose the junction A (SM-EW90-A/B) for charging or status checking. As I see it now, charging would involve at least some disassembly of the cockpit.
One possibly sleek solution would be to fit the new EW-RS910 handlebar junction A into the rear end of one of the aero extensions. However, according to the techdocs, the EW-RS910 is suitable for 20.5-21.5 internal diameter, whereas my (and I guess most) aero extensions are 19.5mm internal. So, pursuing this idea will be probably involve trimming down about 0.5mm of the EW-RS910 housing to make it fit.
Has anyone tried this? If so, could you share your experience? Or, if anyone has a EW-RS910 installed in a 'normal' handlebar, could you assess the feasibility of trimming away about 0.5mm of the casing? Thanks!
