Specialized Stumpjumper 15 EVO Expert

A highly adjustable carbon trail bike that blends big-hit confidence with lively, all-day trail performance.

The Specialized Stumpjumper 15 EVO Expert is built for riders who want one trail bike that can handle demanding descents without feeling slow or cumbersome on the climbs. With a FACT 11m carbon frame, 160 mm RockShox Lyrik fork, 145 mm of GENIE-equipped rear travel and SRAM GX Eagle AXS Transmission, it is ready for technical trails, bike-park days and everything between.

Big-Bike Confidence, Trail-Bike Speed

The Stumpjumper 15 EVO has the travel and geometry to stay calm through rough terrain, while retaining the playful handling and pedalling efficiency that make it a great bike for everyday trail riding. It is made to carry speed, find grip and keep you fresh for another lap.

RockShox GENIE Suspension

A 160 mm RockShox Lyrik Select+ fork works with the RockShox Super Deluxe Select+ rear shock to deliver a confident 160/145 mm suspension package. GENIE technology is designed to provide sensitive early travel for traction and comfort, then build support deeper in the stroke when the hits get bigger.

Adjustable for Your Trails

Adjustable Trail Geometry lets you tune the bike’s handling to suit your preferred terrain and riding style. Whether you want a more responsive setup for local singletrack or a more planted feel for steeper trails, the Stumpjumper 15 EVO gives you room to dial it in.

Wireless Shifting and Tough Wheels

SRAM GX Eagle AXS Transmission delivers crisp, wireless shifting under load, while Roval Traverse HD alloy wheels with DT Swiss 370 hubs are built for hard trail use. It is a practical, high-performance build that is ready to be ridden properly.
