Spotted: SRAM prototype electronic drivetrain

SRAM’s long-rumored development of an electronic drivetrain went public Sunday when a rider in SRAM-branded kit raced on what is clearly a prototype shift-by-wire system at the Illinois cyclocross state championships.

SRAM is remaining tight-lipped about the groupset. “That’s a developmental product. I have no comment,” SRAM marketing manager Michael Zellmann told VeloNews.

With the public, if accidental, unveiling of an electronic group, SRAM joins competitors Shimano and Campagnolo in the steady move away from mechanical shifting.

Little is known about the group, aside from what can be seen in this photo. What is obvious is that an electric wire, not a cable, is actuating the rear derailleur. There is also something mounted to the rider’s stem, which we assume is some sort of battery.

The derailleur is has a short cage, indicating that the initial group will be targeted at the road and cyclocross markets. The shifters are matched with cable-actuated brakes, not the company’s hydraulic braking system.

The finish is rough, and the components are quite obviously in the prototype phase. We hope to learn more soon.

Equally at home on a mountain bike above treeline and chasing down moves in the heat and humidity of a Midwest criterium, Logan Vonbokel is something of an oddity in cycling. Since he first swung a leg over a road bike as a freshman in high school, Logan has been a lover of both cutting-edge technological innovations and the clean lines of classic handmade bikes. Logan joined the tech team in May 2012, bringing with him nearly a decade of high-caliber road racing experience and his undying love for the mud, cowbells, and culture of cyclocross. Logan still races at the Cat. 2 level on the road and in cyclocross, and carries a seldom-used Cat. 1 mountain bike license.
