Trek designer Gary Fisher has the know-how to make a great-riding bike, and he puts his knowledge to work on Trek's Ion CX Pro. It all starts with a light, yet stiff aluminum frame with a carbon fork leading the way that steers, corners and tracks with pinpoint precision and top-notch responsiveness. This is a versatile bike, too, ready to play in the mud at the cross races, commute everyday and do the mid-week hammerfest. It sports wide, 34c tires and has cleverly hidden fender mounts, making it truly utilitarian. Plus, you get a solid parts package with a SRAM Rival group, mud-clearing Avid cantilever brakes and Bontrager's Race tubeless-ready wheels and controls.
