The worst kept secret since, well, for a while, has been the fact that SRAM were to start making mountain bike wheels. I mean when you own ZIPP, the real question is why has it taken so long. Well with anything SRAM that’s because they’ve been testing the crap out of it. Heck when I stayed with Greg Herbold in June he was still testing the Rise 40s. Anyway as of today it’s all official. There’s two models, both available in 26 and 29 sizes, the Rise 40 is alloy and the Rise 60 is Carbon. Both are aimed at the cross-country trail rider and the weights are flippin’ impressive as you can see below.
