All track bikes are fixed gears, but all fixed gears aren't track bikes. With its aluminum frame and steep angles, the Trek T1 is a full-on track bike â€” meaning it would be perfectly at home at a velodrome. That said, it does come with brakes (not pictured) and a tall enough head tube where it can easily serve as a commuter, although the aluminum frame might make the ride a little rough, even with the Bontrager carbon fork. Available only in Starry Night Black, that just means there's one less decision to make. Suggested retail is $960.
