The 2016 Specialized Stumpjumper FSR Comp Carbon 650b satisfies the need for a lightweight carbon fibre platform that can demolish the climbs, while the 27.5” wheel irons out technical descents.

Specialized have chosen a reliable mix of SRAM and Shimano gears and brakes for this Stumpy, with the suspension taken care of by a 150mm RockShox Revelation RC3 fork matched to 150mm of rear travel thanks to a custom Fox Float Evolution CTD rear shock.

The Specialized Stumpjumper name has been on the scene for nearly 35 years, and that’s not by accident. Since the first Stumpjumper FSR back in 1994, Specialized’s continued innovation and evolution of the original 4 bar linkage has resulted in one of the handling trail bikes on the market. The Stumpy is available on interest free finance (0%) with flexible deposit options from £0.

Key Features:

  • FACT 9m carbon fibre Trail Chassis with Stumpjumper FSR M5 alloy rear end blends stiffness with lightweight to form the pinnacle of efficiency, while 150mm of travel, fully enclosed cable routing, and integrated SWAT Door create exceptional handling and zero-hassle storage.
  • Connected with the FSR 6-Pack Linkage, a custom FOX FLOAT Evolution rear shock features AUTOSAG for easy setup and 150mm of plush, adjustable suspension, while the Rx Trail Tune gives a more supple, responsive, and efficient feel for climbing up and descending down the trail.
  • RockShox Revelation RC3 650b fork features a 15mm Maxle Lite thru-axle and 150mm of plush travel to take on hits and bumpy terrain with more control and confidence.
  • 27.5x2.3 Specialized Butcher Control front tyre inspires confidence through any terrain.
  • 27.5x2.3 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 customizable position, ultimately resulting in more control and increased handling on both climbs and descents.
