The 2021 Specialized Fuse Comp 29 Mountain Bike punches way above its weight class thanks to a light-yet-burly M4 aluminum chassis, frame geometry that lends the bike both playfulness and capability, and parts that withstand a serious flogging.

The Fuse is loaded with smart touches. The wide-diameter down tube boosts stiffness. The low-slung top tube improves maneuverability. And while this Fuse's 29x2.6 tires give it a precise, nimble feel, the M4 aluminum frame is also compatible with 27.5+ wheels and tires.

If you fail to nail the geometry, advanced materials and innovative designs still amount to nothing on the trail. Fuse gets it right. The long reach gives you even weight distribution. The slack head angle lends confidence on sketchy descents. The steep seat angle makes quick work of steep climbs.

Highlights include powerful Shimano M4100 disc brakes and a TranzX dropper post.
Shimano Deore M6100 12-speed drivetrain gives you single-ring simplicity and gearing to spare.
