The Giro d'Italia opened this year with a team time trial, and the world's best teams rolled to the start line with the fastest possible gear their sponsors could provide. Most notable was the somewhat-masked appearance of SRAM's wireless time-trial shifters for its not-yet-released electronic group. SRAM-sponsored AG2R La Mondiale had Focus Izalco Chrono bikes with shift buttons on the extensions and base bar wrapped underneath the bar tape.
SRAM declined to comment on the shifters, but we were able to photograph them from several angles. It appears they could function in the same way as the SRAM electronic road shifters, with a single button being used on each side — left shifts the rear derailleur up, right shifts the rear derailleur down and both buttons pressed at the same time moves the front derailleur.
AG2R's Domenico Pozzovivo had bespoke time-trial bars on his Focus Izalco Chrono that provided him an ultra-low position. Pozzovivo, who won stage 3 of the Giro del Trentinto using SRAM electric, crashed out of the Giro on stage 3. Pozzovivo previously told Cyclingnews that he likes electric shifting. "When you get used to it, it feels easier than mechanical gears," Pozzovivo told Cyclingnews.
Wires from four SRAM shifters feed into this junction box, which may communicate wirelessly with the derailleurs
