- The Stumpjumper Comp Alloy 29 combines the balanced stiffness and incredible precision of our sidearm frame design with a 12-speed SRAM NX Eagle drivetrain. The end result is a bike that outperforms its price tag by a wide margin. 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 and shock to the frame, we’ve increased both stiffness and performance over bumps. End result?

Total control. PERFECTLY-BALANCED SUSPENSION Our in-house suspension-tuning team develops custom shock tunes, perfectly paired to each bike’s kinematics. We call this Rx Tune and while it’s not the easy way to build a suspension bike, it’s worth it. You feel Rx Tune as perfectly-balanced suspension. MASSIVE BANG FOR YOUR BUCK

- Roval Traverse 29er wheels roll over obstacles and maintain momentum with ease.

- FOX DPS Performance rear shock delivers perfectly-dialed rear suspension.

- NX Eagle 12-speed drivetrain gives you single-ring simplicity and gearing to spare.
