Specialized Stumpjumper 15 EVO Expert DI2 Bike 2026 Gloss Nebula Metallic/Dolomite Metallic

Drop into rough, technical lines and you’ll feel this bike stay composed as the trail gets unpredictable. It tracks clean through rock gardens, holds steady in fast corners, and still feels lively when you’re pumping rollers or popping off trail features.

The Specialized Stumpjumper 15 EVO Expert DI2 runs a FACT 11m carbon chassis with 145mm rear travel, paired to a FOX FLOAT 36 Performance Elite fork with GRIP X2 damper and up to 160mm travel. Shimano XT Di2 handles 12-speed shifting, while the FOX FLOAT X Performance Elite shock with GENIE Shock Tech and Ride Dynamics Trail Tune manages rear suspension control.
