Product Details

STILL LEAVING ITS COMPETITION IN THE DUST after decades in production, the Stumpjumper® Hardtail makes no apologies for being the leanest, lightest (some models are under 20 lbs.) and most precision hardtail on the market. Tradition works.

A 29" wheel version of our classic. The fully manipulated M5 alloy frame delivers superior ride quality, while the shared tube mono-stays increase lateral rigidity, and special forged dropouts let you switch to single speed.
