Description
Rip up the trails on the Specialized S-Works Stumpjumper Mountain Bike, designed to excel no matter the terrain. Grams have been shed with no negative impact on durability, and the carbon frame is stiff and responsive, with adjustable FlipChip geometry to account for different ride types and riding styles.
The FOX Factory fork and shock keep things smooth and the suspension kinematics have had an overhaul to deliver more refined performance. A progressive leverage ratio means smaller bumps are soaked up with ease and there's less risk of bottoming out on big hits so speed is retained even over the rougher stuff. Enhanced anti-squat equals more efficient pedalling and, consequently, more efficient climbing, and the progressive geometry is low, long and slack for better stability and confidence when things get gnarly.
As with all of Specialized's bikes, Rider-First Engineered™ design is present, and creates equally good handling and ride feel across the range of sizes. SWAT™ storage in the downtube allows you to keep your pockets light.
SRAM XX1 Eagle AXS components take care of shifting duties, with the 1x12-speed setup offering a huge range and smooth functionality. SRAM G2 Ultimate hydraulic disc brakes bring confidence at speed, working well in all conditions. A dropper post with frame-size specific travel allows you to move the saddle down to shift your weight when approaching obstacles and descents.
