Trek's Cronus Ultimate, is a unique frame designed by a unique bike guru, Gary Fisher. He created it for everyone from national champs to weekend warriors, with an incredibly light monocoque-carbon frame, Trek's E2 front end that dramatically increases stiffness and steering, and a BB90 bottom bracket for awesome power transfer. Equally unique is that this beauty boasts room for up to fat 34c tires and hidden fender mounts so it'll do double duty as a commuter or everyday rider. So crush the cross course on Saturday and ride it to the office on Monday. Just don't forget to wash it.
