To squeeze every last ounce of fun out of the trail, you need a bike that can take a hit and dish it right back out ten-fold. 


In other words, you need the Stumpjumper FSR Comp 6Fattie. It features a M5 alloy construction that's lightweight and durable, but what we're most excited to debut is our all-new 6Fattie Wheel System. It takes 650b wheels and wraps them in 3.0" tyres in order to achieve levels of traction, control, and floatation that will shake your idea of trail riding to the core. And when you combine a mix of SRAM's most durable components with a our 6Fattie Trail Geometry that maintains a roomy top tube, ultra-short chainstays, and a slacked out front end, you're looking at the future of trail bikes.



  • M5 alloy Trail Chassis with Stumpjumper FSR rear end blends durability, stiffness, and light weight, while 135mm of travel Trail Geometry give more than capable handling.
  • RockShox Revelation RL fork features a 15mm Maxle Lite thru-axle and 150mm of plush travel to take on hits and bumpy terrain with more control and confidence.
  • Roval Traverse 650b alloy wheels work in tandem with the ultra-wide tires to give you loads of extra traction, floatation, and control.
