Carve up the mountain, whatever the trail, whoever the rider with the Stumpjumper 15 Alloy Mountain Bike from Specialized – setting a new precedent for full sus bikes thanks to its S-sizing; six distinct geometries to choose from so you can hone your trail performance for any style, on any terrain. The low bottom bracket, slack headtube angle and optimised fork offset combine together to create a stable, comfortable ride that’s even more customisable in the head angle and bottom bracket.

The M5 Alloy chassis has been engineered as a single unit from the front end to the rear and everything in between, reaching the Specialized’s stiffness target, perfectly adapted for trail biking. Introduced to increase your storage space, the SWAT™ door enables you to keep cycling essentials on hand, even as you ride.

Fitted with a hardy 12-speed Shimano Deore drivetrain, RockShox Psylo Silver fork optimised with Motion Control Damper and reliable Shimano MT-420 4-piston brakes for efficient speed reductions when that corner creeps up on you, the Stumpjumper 15 Alloy delivers balance efficiency, ultimate traction and total control on hairy descents and narrow corners, whatever the terrain.
