What happens when you merge two worlds of innovative technology and pedigree? You get the future of trail bikes, aka, the Stumpjumper FSR Comp Carbon 6Fattie. 


It features our all-new 6Fattie Wheel System that takes 650b wheels and wraps them in 3.0" tyres. The result? Levels of traction, control, and floatation that will shake your idea of trail riding to the core. And to set things over the top, we designed it work seamlessly with the revolutionary new Stumpjumper FSR frame. The frame is constructed with a FACT 9m carbon fibre Trail Chassis that's been paired with an M5 alloy rear end in order to give an ultra-lightweight, strong, and stiff frame. 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 a build spec that mixes some of SRAM's most durable and dependable components, you have one of the most forward thinking bikes that we've ever made. Change the way you ride.



  • FACT 9m carbon fiber Trail Chassis with Stumpjumper FSR M5 alloy rear end blends stiffness with light weight to form the pinnacle of efficiency, while 135mm of travel, fully enclosed cable routing, and integrated SWAT™ Door create exceptional handling and zero-hassle storage.
  • RockShox Yari 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 2Bliss Ready wheels provide a strong, stable platform that's built to deliver heaps of responsiveness, speed, and supreme handling.
