Specialized Stumpjumper 15 EVO Expert Di2 2026

One Bike to Rule All Trails

Capability, Control, Personalization

The all-new Stumpjumper 15 EVO obliterates every trade-off in the trail game. It’s the ‘Bike of the Year’ winning Stumpy 15 you know, turned up to 11—with a longer-travel 160mm FOX fork, external reservoir FOX FLOAT X shock, and a slacker headtube for next-level capability. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. A heaping helping of personalization to make it perfect for the only rider who matters—you? Check, check, check.
