Manufacturer Description

The Stumpjumper 29 combines the amazing ride quality and precision of our alloy sidearm chassis with plush RockShox suspension and a 12-speed SRAM SX Eagle drivetrain. Bottom line: It's a bike that outrides both its price tag...and bikes costing much more. 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. 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. It's total control. MASSIVE BANG FOR YOUR BUCK • RockShox 35 Gold RL fork and Deluxe Select shock erase rocks and roots. • SX Eagle 12-speed drivetrain gives you single-ring simplicity and gearing to spare. • Roval Traverse 29er wheels roll over obstacles and maintain momentum with ease.
