The 15th version of the Stumpjumper is here and ready to unleash a combination of capability, control, and personalization of all-out performance for any rider on any trail. Devour big hits? Check. Short-travel control, playfulness, and efficiency? Check. Increased traction and tunability? Check.
GENIE Suspension
Without a doubt, the biggest breakthrough is GENIE Shock Technology. 145mm of rear wheel travel gives the Stumpy 15 that magic carpet ride trail riders have been asking for. After countless hours of testing and pouring over gathered data, the wish was granted. The feel and control of a coil spring with better bottom-out prevention, incredible traction, and more tunability. The best of both worlds. No compromising.
SRAM S1000 AXS Transmission
Wireless 12-speed Transmission delivers crisp and precise shifts across a wide range of gears to suit any trail condition. Simply press the controller while powering over obstacles, muscling up technical climbs, and shredding downhill, SRAM engineered the Transmission to shift under maximum load. The flat-top chain brings a unique design while being incredibly strong. Go ahead and give it everything you got.
FACT 11 Carbon Frame
Specialized has perfected trail geometry. Big bike capability mixed with lively and efficient climbing characteristics. A generous cockpit centers you on the bike for amazing traction and cornering control. The low bottom bracket and slack head tube angle keep things stable through the rough sections. Play with the many geo settings or send just like it was intended.
SWAT 4.0
Elevating the downtube storage game once again. SWAT 4.0 brings the smoothest, most weather-resistant flush mount design yet. Stash tools, nutrition, water filter, burrito, however you want to go.
Lightweight FACT 11 Carbon frame with six different geometry settings to match ride style and terrain
Ride Dynamics tuned FOX FLOAT with GENIE technology provides maximum grip and traction, bottom-out prevention, and unlimited tuneability
