Trek designer Gary Fisher knows a lot about cross bikes. He's raced them, ridden them for years, even reviewed them for cycling publications. With that knowledge he presents the Ion CX, which he calls to;smartly unique.to; It boasts Trek's super-stiff aluminum frame with a carbon cross fork for a nimble, efficient ride that simply flies. But the really unique part is the fact that it sports wide, 38c tires and even provisions for fenders. So, this is a full-on race-ready bike that's stiff, light and tackles the toughest, messiest courses out there. It also excels at commuting and winter training, or just enjoy it all-year long. And nothing shows off its workhorse pedigree like its precision Shimano 105 gruppo, Avid cantilever brakes and Bontrager components and wheels.
