Spotted by Jayson of GravelCyclist.com while riding along with the AG2R during training in Australia prior to the Tour Down Under, these SRAM wireless electronic front and rear derailleurs are looking pretty darn polished.

Mounted to Christophe Riblon’s Focus Izalco Max road bike, there’s at least one detail we hadn’t quite picked up on in the already profuse collection of photos and technical data we’ve amassed on this group. The tops of each derailleur appear to have a similar looking hatch, which we’re guessing hides the charging port. Micro-USB would be our guess, since it would allow both charging and firmware updates. Plenty of closeups and links below…

One interesting note is they appear to be running the base-level SRAM PG1130 cassette rather than X-Glide. With rumors that the new electronic group is the lightest battery-powered shifting system to be offered (when, of course, it actually is offered), could just be that the heavier cassette helps team bikes meet minimum weight limits.

Electrical tape covers the wire ports. Bike manufacturers may have to start putting the wire ports in less conspicuous locations if this stuff takes off!

The black tail end of both derailleurs look very similar, suggesting those are the battery packs and are likely replaceable. That would be a nice feature considering team mechanics could quickly swap out batteries from the car in a pinch, assuming it’s a tool-free process. Either way, it’s a nice precaution for pro-level use and for anyone doing RAAM.

Huge thanks to Jayson for the pics!
