SRAM leaked its much anticipated electronic groupset at the Midwest regional championship Cyclocross Championships in the US last December and is now making an appearance at the Tour of California on the Bissell Development Team bikes. GCN caught some footage.
We still don’t know much about the groupset, but here’s what what’s speculated:
– We’ve heard that it’s wireless, but as you can see from the video there are wires. I haven’t seen the groupset up close, but my guess is that wires would be needed for battery power. Otherwise a battery would be needed on each of the shifters and both derailleurs which adds complexity, weight, and bulk. The shifting transmission might well be wireless, we don’t know.
– From what I hear, the way that the shifting works is that there is one button on each of the brake levers. The left lever shifts up, the right lever shifts down (or vice versa). Press them both at the same time and the front derailleur shifts up or down. This is unconfirmed, but I’ve heard this from various sources.
– How far away from production is it? No idea, but it still looks like it’s in the prototype stage.
