Specialized S-Works Stumpjumper 27.5" Mountain Bike 2019
Specced to the highest level, the Specialized S-Works Stumpjumper 27.5" Mountain Bike has a full FACT 11m carbon frame and fork, 150mm of travel in the front and rear suspension, and offers low weight and unrivalled handling, efficiency and stiffness. A full SRAM XX1 Eagle drivetrain shifts smoothly and precisely across the cassette, and SRAM Guide RSC hydraulic disc brakes ensure braking performance no matter the terrain or conditions.
There's room for tyres up to 3.0" wide, and the frameset is built up with top carbon 27.5" wheels and tubeless ready tyres. This bike is ready to take on anything you throw at it.
- The Stumpjumper's asymmetrical, S-Works FACT 11m carbon fibre construction is lightweight, stiff, and ready to take on the trail. It's built off Specialized's 27.5 Trail Geometry, so it offers the right amount of capability and comfort. And with SWAT™ integration in the down tube, a threaded BB, easy cable routing, and an all-new chain silencer, it's ready for anything the trail, or you, throw at it
- FOX FLOAT DPX2 Factory has three modes—Open, Trail, and Firm—that control large compression adjustments on-the-fly. There's also a tool adjust compression adjustment that allows for fine-tuning of the compression in Open mode
- Legendary FIT4 damper, large stanchions, buttery-smooth Kashima coating; the FOX 36 Factory 150mm fork is one of the best out there
