Our Stumpjumper ST models are snappy & nimble, yet Incredibly versatileâ€”the perfect rigs for riders seeking both efficiency & capability. The Stumpjumper ST Alloy 29 makes that winning combo affordable, with components that are big on performance & small on dollar signs.
THE ULTIMATE TRAIL BIKE
The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end & shock to the frame, weâ€™ve increased both stiffness & performance over bumps. End result? Total control.
Our in-house suspension-tuning team develops custom shock tunes, perfectly paired to each bikeâ€™s kinematics. We call this Rx Tune & while itâ€™s not the easy way to build a suspension bike, itâ€™s worth it. You feel Rx Tune as perfectly-balanced suspension.
