Description
The Specialized Stumpjumper Comp 650b Mountain Bike is a rugged, efficient and nimble choice, ideal for the rider who enjoys chewing up rough off-road trails all year round.
With a one-by setup, this bike is far less likely to drop its chain, even when riding over the bumpiest terrain. SRAM GX derailleurs and trigger shifters deliver smooth and near-instant gear changes, so you can get on with enjoying your ride.
A generous 150mm of travel in both the RockShox Reba RL fork and the Stumpjumper FSR rear shock make the most unforgiving surfaces feel smooth and compliant.
A strong and stiff 27.5 inch wheelset with Roval rims finishes out this specification, with tubeless ready rims to make the most of the latest in tyre technology.
Please note: The image is shown for representation of colour way only, specification subject to change at any time. Bicycles do not come with pedals unless otherwise specified.
