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.
