2018 Specialized Stumpjumper FSR Comp Carbon 650b Mountain Bike

When you need all of today's tech and an agile wheel size, you can't beat the Stumpjumper Comp Carbon 650b.

It features FACT 9m carbon fibre for the bulk of the construction in order to provide an ultra-lightweight, strong, and stiff frame. The carbon moulding process also revolutionised 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.

You'll also find an aggressive, nimble geometry to complement the 650b wheels that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end. The build spec'd SRAM's GX 11-speed shifting, a RockShox Revelation RC fork with 150mm of travel, a custom-tuned Monarch RT at the rear, and Roval Traverse 650b alloy wheels. It'll change the way you ride.

• FACT 9m carbon fibre Trail Chassis with Stumpjumper FSR M5 alloy rear end blends stiffness with light weight to form the pinnacle of efficiency, while fully enclosed cable routing and an integrated SWAT™ Door create exceptional handling and zero-hassle storage.
• RockShox Revelation RC 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.
• SRAM's 11-speed GX groupset features a wide gear range that delivers climbing and descending efficiency in spades. On top of this, the one-by setup is notorious for being next to impossible to drop a chain with, plus it provides a significant weight savings in comparison to a standard two-by setup.
