Stumpjumper FSR Expert Carbon 29

2017 Stumpjumper FSR Expert Carbon 29

If you know the history of the Stumpjumper FSR, you know that it doesn't believe in compromising. And not surprisingly, this still rings true today with the Stumpjumper FSR Expert Carbon 29. It features SRAM's workhorse 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 a FACT 9m carbon fibre 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.
