The Stumpjumper 15 brings new GENIE shock technology to the venerable trail bike, which sees more travel and further refinements.
Incredible suspension performance thanks to GENIE shock tech
Excellent fit and geometry
Build kit is on point and delivers excellent value
Refined frame design and features
Stock wheels on the Comp build are under-gunned for the Stumpy’s capabilities

The alloy Stumpy packs a punch for the price, and you can run a cable-actuated derailleur.
Suspension is impressively sensitive
Extensive adjustment to alter geometry, wheel size, and shock performance
Can descend like a bigger bike
Quite heavy for a trail bike, due primarily to frame weight
Genie shock warrants extended setup testing
Can be hard to balance sensitivity and support
