When you need all of today's tech, blended with a durable component spec, and an agile wheel size, it's tough to beat the Stumpjumper FSR Comp Carbon 650b. 


It features a durable selection of components from SRAM, hand-selected to ensure that you get the most performance over rugged terrain possible. At the frame, you'll find our FACT 9m carbon fibre Trail Chassis with an M5 alloy rear end that creates a lightweight, strong, and stiff construction. The carbon molding process also allowed us to revolutionize how you carry your trail essentials with the all-new SWAT™ Door found at the down tube. This compartment will fit a tube, a tool, and pump without rattling or compromising the structural integrity of the frame. And when you factor in our proprietary Rx Trail Tune at the shock, plus an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end, you have a bike that's going to eat up the trail and ask for seconds.



  • FACT 9m carbon fiber frame construction w/ M5 alloy rear end blends stiffness with light weight to form the pinnacle of efficiency, while 150mm of travel, fully enclosed cable routing, and integrated SWAT™ Door create exceptional handling and zero-hassle storage
  • RockShox Yari RC fork features a 15x110mm Maxle Ultimate thru-axle, a Solo Air™ spring, and 150mm of plush travel to take on big hits and bumpy terrain with supreme speed and efficiency.
  • Roval Traverse 650b wheels give a strong, stable platform that's built to deliver heaps of responsiveness, speed, and supreme handling.
