For 2016, FSA and Vision are making major revamps to cranks, wheels, bars and stems. More intriguingly, in the same week SRAM finally took the wraps off its Red eTap electronic drivetrain, FSA also showed off a prototype of its own wireless shifting system, which was spotted in the wild at this year's Tour de France.
FSA road range: No-wires groupset preview

Let's deal with that juicy glimpse of wireless groupset first of all. Although reps remained tight-lipped as to technical details, we did get a chance to have a good look over the group and fiddle with the gear shifting on what was a fully working prototype.
The main point of difference seems to be with the levers. Sitting behind the brake lever are two-way rocker switches that handle up and downshifts (right lever for the rear derailleur, left lever for the front).
While shifting is wireless, both derailleurs had wires coming from them and running into the normal channels of the S-Works Tarmac frame they were fitted to, which suggests one central battery supplying power to the derailleurs while the levers have their own independent power source. As we say, this is only speculation but FSA did tell us that the system isn't far away from completion – so we look forward to being able to test the group in anger out on the road.
