If your idea of trail riding follows the philosophy of "go big or go home," you simply can't beat the agility and responsiveness that a 650b gives. 


Knowing this, we built our Stumpjumper FSR Expert Carbon 650b to be the ultimate all-rounder trail bike. It features a workhorse SRAM one-by groupset and the no-holds-barred Guide R hydraulic disc brakes to round out a build that places an equal focus on durability and efficiency. 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 truly do get a bike that refuses to compromise.


  • 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 150mm of travel, fully enclosed cable routing, and integrated SWAT™ Door create exceptional handling and zero-hassle storage.
  • RockShox Pike RC 650b fork features a 15mm Maxle Stealth thru-axle and 150mm of plush travel to take on big hits and bumpy terrain with supreme confidence and efficiency.
  • Roval Traverse 2Bliss Ready wheels give a strong, stable platform that's built to deliver heaps of responsiveness, speed, and supreme handling.
