If you're searching for one bike to do it all, look no further than Trek's CrossRip. This machine loves long rides on the road, cruising along dirt roads, commutes in the city and even down-n-dirty cyclocross racing. Its Trek light aluminum frame is lively, fast and ridiculously fun to ride. Shimano gives you a 24-speed drivetrain perfect for the steepest hills and Tektro provides their excellent brakes for speed control. And since you get fender and rack mounts as well, you have great off-season and gear-hauling capacity to boot!
