Specialized Stumpjumper Pro Mountain Bike 2022
Engineered to breeze climbs and blitz descents, the Specialized Stumpjumper Pro Mountain Bike is a true all-rounder that rips on all gradients. A name synonymous with performance, this latest revision of the Stumpjumper takes that same well-known formula and amplifies its abilities. This is a model that any rider can appreciate, with its 130mm of composed suspension travel punching well above its weight on the trail and progressive geometry ensuring it handles like a dream.
The high-quality carbon frame utilises a FACT 11m layup for a stiff and lightweight ride. To ensure peak-performance across the size range, Specialized use their Rider-First Engineered™ approach, which sees all frame sizes offer the same balanced front and rear stiffness. A SWAT™ door allows you to ditch the backpack in exchange for in-frame storage and features enough room for a pump, spare tubes and more.
The glistening specification truly earns this bike its Pro moniker. SRAM G2 RSC brakes offer premium power without sacrificing a low weight, and the wireless SRAM AXS X01 drivetrain delivers intuitive shifting across its wide 12-speed range. Fast-rolling 29” Roval Traverse carbon hoops are laced to the race-ready DT Swiss 350 hubs, and a FOX 34 Factory fork offers 140mm of plush, trail-ready suspension.
