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.
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.
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
