Specialized Stumpjumper 15 EVO Expert Di2 Mountain Bike 2026 - Enduro Full Suspension MTB
The Stumpjumper 15 EVO Expert Di2 is built for riders who want to push harder, ride faster, and explore more challenging terrain. At its heart is a FACT 11m carbon chassis with 145mm of rear travel and a slacker geometry that increases capability on steep descents. Specialized’s EVO Trail Geometry keeps things playful and stable, while SWAT™ frame storage provides a tidy space for trail essentials. Adjustable geometry lets you fine-tune the head angle and BB height to match your riding style or local trails.

- FACT 11m carbon frame, Trail Geometry, SWAT™ storage, 145mm rear travel
- FOX FLOAT 36 Performance Elite fork, 160mm front suspension travel
- FOX FLOAT X shock with external reservoir, 145mm rear suspension travel
- Shimano XT Di2 12-speed electronic drivetrain

Up front, the FOX FLOAT 36 Performance Elite fork provides 160mm of supple, controlled travel, backed up by a FOX FLOAT X shock tuned by Specialized Ride Dynamics. The rear shock features the new GENIE compression system and an external reservoir for improved heat management and consistent damping.
Shifting is handled by Shimano’s XT Di2 drivetrain, offering smooth, precise 12-speed gear changes at the touch of a button, even under load. Shimano Deore XT 4-piston brakes with finned metal pads offer confident stopping power when things get steep or fast. A mixed wheel setup—29" front and 27.5" rear on smaller sizes—adds to the bike’s agility and stability, with Butcher and Eliminator GRID Trail tyres providing serious grip.
From tight switchbacks to big-mountain descents, the Stumpjumper EVO Expert Di2 is a cutting-edge trail bike that offers superb control, climbing efficiency, and customisable ride feel.
