When you need to blend ruggedness, efficiency, and down right nimbleness into one trail bike, it's pretty damn hard to beat the confidence inspiring construction of an alloy frame like the Stumpjumper FSR Comp 650b. 


It features an M5 alloy construction that's lightweight, durable, and plenty stiff and compliant, while SRAM's most durable one-by components have been hand-selected to ensure that you get the most performance over rugged terrain possible. And when you factor in our proprietary Rx Trail Tune at the shock, plus an aggressive, trail-eating geometry that features absurdly short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end, you get a trail bike that you can be confident in, season after season.



  • 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 provide a strong, stable platform that's built to deliver heaps of responsiveness, speed, and supreme handling.
