Specialized S-Works Stumpjumper FSR Carbon 650B Mountain Bike 2016
When the best simply won't cut it, you need to go beyond. The Specialized S-Works Stumpjumper FSR Carbon 650B Mountain Bike 2016 does just this. A carbon layup with top of the line FACT 11m means this frame's stiffness, strength and versatility will feel like nothing you've ever ridden.
The 650B tyres and Roval Traverse SL 650b eat up the trail and the optimised Trail 650b geometry combines aggressively short chainstays, a roomy top tube, a low bottom bracket and a slacked out front end for all-terrain mastery. Rx Trail Tune on the shocks alongside a drivetrain and breaking spec that would make even the most seasoned pros blush means you'll be ready to conquer any trail.
Features:
- FACT 11m carbon fibre Trail Chassis with Stumpjumper FSR full carbon rear end blends stiffness with light weight to form the pinnacle of efficiency, while fully enclosed cable routing and an integrated SWAT Door create exceptional handling and zero-hassle storage.
- Connected with our FSR 6-Pack Linkage, a custom FOX FLOAT Factory rear shock features AUTOSAG for easy setup and 135mm of plush, adjustable suspension, while our Rx Trail Tune provides a more supple, responsive, and efficient feel for climbing up and descending down the trail.
- RockShox Pike RCT3 650B fork features a 15mm Maxle Ultimate thru-axle and 140mm of plush travel to take on big hits and bumpy terrain with supreme confidence and efficiency.
- 650bx2.3” Specialized Butcher Control front tyre inspires confidence through any terrain.
- 650bx2.3” Specialized Purgatory Control rear tyre delivers reliable traction over a diverse section of soils and conditions.
- Command Post IRcc seatpost features 12 positions of up to 125mm of height adjustability for a more customisable position, ultimately resulting in more control and increased handling on both climbs and descents.
