2021 SPECIALIZED STUMPJUMPER EXPERT MOUNTAIN BIKE
The Specialized Stumpjumper Expert Mountain Bike is designed to boost your trail game, making it the perfect tool to improve your riding. 130mm of trail-optimised suspension provides unbeatable descending prowess for its travel category, with revised suspension kinematics making full use of the travel on offer. State of the art frame technology sees serious weight reductions for a feather-weight frame, without sacrificing durability and stiffness.

Do not let the short travel numbers fool you - the Stumpjumper Expert descends like it is on rails, with its lively ride character looking to pop every lip and roost every berm. Featuring a more progressive leverage curve than prior models, the 130mm of travel on offer feels bottomless on big hits and reactive on chattery terrain. Improved pedalling characteristics and a steep seat-tube angle allows this bike to decimate tough climbs, making it an excellent choice for the modern trail rider.

A roomy top-tube and low BB provide confidence for the steeps, keeping you planted through rough terrain. Taking notes from the Enduro and Demo designs, Rider-First Engineered™ sizing allowing you to pick a frame size that suits your riding, not your build. Low seat-tube heights allow you to size up for stability, or size down for a more playful ride - the choice is yours. A yoke mounted flip-chip offers half a degree of head angle adjustment, helping to further fine-tune your fit.

Improved SWAT™ Door integration provides more storage for your tools, nutrition and spares, and a ribbed chainstay protector dampens unwanted drivetrain noise. The Expert is geared towards high-performance riding, and the parts specification reflects its fast intentions. Tubeless-ready 29" Roval Traverse wheels offer quick engagement and the strength to deal with the occasional hang up, and the SRAM XO1 never misses a beat for precise shifting. SRAM G2 RSC brakes offer high-quality stopping power, providing glue-like grip when combined with the Specialized GRIPTON® tyres.
