Ex-Demo: Specialized Stumpjumper FSR Comp Alloy 650b Mountain Bike

As this is not a brand new bike, it may not feature the full original technical specification and is subject to change.

When you hit the trails, you want a bike that will deliver ruggedness, efficiency and nimbleness all in one, and it's hard to beat the confident construction of an alloy frame like this.

With an M5 alloy construction that's lightweight, durable, stiff and compliant, the Stumpjumper Comp Alloy 650b also features SRAM's most durable one-by components that have been hand-chosen to give you the most performance over rugged terrain possible. Combining a proprietary Rx Trail Tune at the shock, aggressive, trail-eating geometry that features absurdly short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end, gives you a nimble trail bike that you can be confident on, season after season.

• M5 alloy Trail Chassis with Stumpjumper FSR rear end blends durability, stiffness, and light weight, while 150mm of travel Trail Geometry provide more than capable handling.
• A RockShox Reba RL fork handles suspension up front with ease, soaking up bumpy terrain with 150mm of plush travel.
• SRAM's 11-speed GX groupset features a wide gear range that delivers climbing and descending efficiency in spades.
• 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.
