Trek's 4500 is great for around the campus, commutes to work, running errands, and of course, epic singletrack adventures, too. Trek's Alpha Black aluminum frame feels light enough to float yet is built plenty tough to hold its own in the durability department. Plus, this sweet ride boasts a RockShox Dart 3 suspension fork for comfort and control, an easy-pedaling 24-speed Shimano drivetrain, powerful Avid linear-pull brakes and a host of quality Bontrager components you'll love.
