Santa Cruz recently announced the debut of their all new, all-carbon V10 downhill bike. Sure, we’ve tested the carbon V10 before, but that version has an aluminum rear end. This new bike features a carbon rear end, co-developed with Enve Composites, and an all new carbon front triangle and carbon rocker. How light is it? With a RockShox Vivid Air on the back end, you’re looking at less than seven pounds. Yeah, holy crap, indeed. And before you jump to the conclusion that anything that light can’t ever be strong enough to race DH, consider this: the Santa Cruz Syndicate raced the entire 2012 season aboard this chassis.
