One gear means two speeds. Riding and walking. A Stumpjumper single speed helps you spend more time doing the former.
  • Fox F29RL 90mm air-sprung fork with rebound/compression adjust and lockout is everything you need for this true-to-the-trails 29er
  • Custom DT Swiss 29" rims with eyelets and sleeved seams are paired with a DT Swiss singlespeed hub to keep weight low and durability high
  • Avid Elixir R SL lightweight hydraulic disc brakes/levers with alloy backed semi-metallic pads and tool-less reach adjust for superb control and modulation
  • S-Works The Captain front and Renegade rear 29 x 2.0" dual compound 2Bliss Ready tires with aramid bead roll fast and still provide plenty of race-tested traction
  • 29er singlespeed HT frame with curved top tube looks as fast and sweet as it rides due to its race-optimized 29" geometry and M5 manipulated alloy construction, it's the lightest eccentric BB set-up available
