Specialized Stumpjumper Evo Pro Mountain Bike 2022
Engineered from the ground up to be a versatile trail ripper, the Specialized Stumpjumper Evo Pro Mountain Bike features adjustable geometry to deliver full-gas performance on any terrain. Lightweight and durable, the carbon frame construction is stiff and robust and sees SWAT™ storage in the downtube to carry a tube, pump and more. The 29” wheels are fast-rolling and help to iron out trail chatter, while the 150mm of plush, progressive suspension travel flattens out big hits.
Channelling the Demo and Enduro models, the suspension kinematics of this model have been revised for enhanced performance. Enhanced anti-squat reduces pedal-bob for more efficient climbing, and square edge hits are devoured with total composure to retain speed in the rough. The progressive geometry is low, slack and long to boost confidence on steep, gnarly terrain, and features a tuneable headset cup and chainstay-mounted flip-chip for unparalleled levels of adjustment.
Truly wireless, the SRAM X01 AXS drivetrain takes your shifting experience to the next level. Customisable through the accompanying app, this 12-speed drivetrain is simple to set up and offers instantaneous shifting across the entire 10-52t range. The SRAM Code RSC brakes feature four pistons for outrageous levels of power, yet offer impressive levels of modulation for total control on steep descents. The FOX factory suspension provides a wide degree of tunability and feature a slick Kashima coating for plush performance.
