Specialized S-Works Stumpjumper ST 29" Mountain Bike 2019
There's room for tyres up to 3.0" wide, and Roval Traverse SL 29" carbon wheels are included for fast and smooth rolling over the roughest terrain. SRAM's XX1 Eagle drivetrain matches this frames performance attributes perfectly so shifting is precise, smooth and reliable across the cassette. Hydraulic SRAM Guide RSC disc brakes ensure braking is powerful and modulated no matter the conditions.
- The Stumpjumper ST's asymmetrical, FACT 11m carbon fibre construction is lightweight, stiff and ready for technical climbs and rowdy descents. Built off Specialized's 29 Trail Geometry, it's both capable and comfortable
- With SWAT™ integration in the down tube, a threaded BB, easy cable routing, and a brand new chain silencer, it's ready for anything the trail, or you, throw at it
- The FOX DPS Factory rear shock features Specialized's Rx Trail Tune, ensuring that no matter the wheel or frame size, your bike is dialled-in perfectly
- With the legendary FIT4 damper, large and lightweight stanchions, and buttery-smooth Kashima coating, the FOX 34 Factory 130mm fork is one of the best out there.
- Roval Traverse SL 29 wheels are full carbon and light stiff and strong
- Full 12-speed SRAM XX1 Eagle drivetrain
- Powerful SRAM Guide RSC hydraulic disc brakes
