Details
Our ode to Downieville—one of the greatest riding spots on earth. This limited-edition ST model is the perfect choice for long, grueling rides that demand a quick, efficient—and burly—machine. Lightweight carbon 29er chassis, custom suspension, powerful disc brakes, and more. Since the trails around Downieville inspired this limited-edition model, we're donating a portion of the proceeds from every one of these bikes to the Sierra Buttes Trail Stewardship, a group whose tireless work has made Downieville and the surrounding area such an amazing place to ride.
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.
A FEATHERWEIGHT BRAWLER
This limited-edition ST model combines the nimble, carbon Stumpjumper ST chassis with longer-travel, RockShox suspension, precise SRAM XX1/X01 Eagle drivetrain, and massive stopping power. It's a very cool, and very rare, flavor of Stumpjumper.
BRILLIANTLY CUSTOM
- A bomber RockShox Lyrik Select Plus fork dishes out 140 millimeters of travel.
- 130-millimeters of supple rear suspension via a RockShox Super Deluxe Select Plus
- Big stopping power courtesy of Magura MT5 4-piston discs and massive rotors

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.
