Stumpjumper 15 EVO Alloy
The Stumpjumper 15 EVO Alloy is built to crush every trail trade-off—delivering big-bike bump absorption, short-travel playfulness, and ultimate customization in one package.
At its heart is our groundbreaking GENIE Shock Technology, blending coil-like grip and traction with air-spring bottom-out control and tunable support. The result? Up to 57% better traction, 39% fewer bottom-outs, and a ride that feels like more travel than its 145 mm rear suspension suggests.
