This speed demon from Specialized is perfect for shredding any cross-country course. With an exceptionally low weight, the S-Works Fast Trak also features minimal rolling resistance and a high-volume casing for a plush ride. The large footprint with aggressive side knobs hooks up in the corners, while the short, spaced center knobs with ramped edges keep you cruising fast. The soft tread compound grips great, and it's tubeless ready so you can run low pressures without worrying about pinch flats.
