Starting June 19, 2025, the new MY26 Stumpjumper 15 models will officially be renamed Stumpjumper 15 EVO, because this bike has earned its stripes.
Born from rider and retailer feedback and evolved through meaningful, performance-focused spec updates. This isn’t just a name change, it’s an upgrade in capability. With more travel and more control, the MY26 Stumpjumper 15 EVO punches well above its weight and now wears the name to match.
Why EVO?
Because when the trail turns up, down, or sideways—this bike doesn’t flinch.
