Calm under pressure, yet deft and precise, the 2023 Specialized Fuse 27.5 Hardtail Mountain Bike is an entirely different kind of hardtail. Featuring an all-new longer, lower, and rowdier chassis and 27.5x2.3 wheels and tires, the Fuse 27.5 handles rough, sketchy descents and steep, technical climbs with absolute confidence.

The Fuse is loaded with smart touches. The wide-diameter down tube boosts stiffness. The low-slung top tube improves maneuverability on tight trails. And while this Fuse’s 27.5x2.3 tires give it ample traction and stability, it’s also compatible with 29er wheels and tires.

Fail to nail the geometry and advanced designs will 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.
