Specialized 2026 Stumpjumper 15 EVO Expert Full Suspension Mountain Bike

The 2026 Specialized Stumpjumper 15 EVO Expert Full Suspension Mountain Bike is a beefed up version of the standard Stumpjumper with more travel so you can take bigger hits. The biggest innovation on the Stumpjumper 15 is GENIE.

This patent-pending air spring technology, invented by Specialized, delivers three key innovations: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tuneable platform for a playful feel. Extensive field testing proves that Stumpjumper 15 with GENIE delivers 57% better traction than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance, which keeps the wheel in contact with the ground a greater percent of the time than a typical air spring would.

The Stumpjumper 15 comes with adjustable geometry. Six distinct geometry settings allow you to tune performance for any style, any terrain.

The head angle and bottom bracket height can be fine-tuned for stability or clearance. The Stumpjumper 15 EVO Expert comes with a longer-travel 160mm FOX fork, external reservoir FOX FLOAT X shock, and a slacker headtube for next-level capability.

Shimano XT Di2 gearing gives seamless shifting. This bike is perfect for Trail mountain bike riders who want extra travel or enduro riders who want a lighter weight bike.

The Stumpjumper Evo has big hit capability built on a light carbon chassis with tuneable geometry.
