Surly Karate Monkey Hardtail Mountain Bike Description:
Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Originally designed as a 29er (and the frame that helped spark the 29” wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. This allows you to pick your poison — provided your poison is having a really great time while permanently donning an ear-to-ear grin, of course.

- 100% Surly Chromoly steel frame, double-butted main triangle and 44mm headtube
- Frame tubeset uses Surly custom trumpet tubes for greater stiffness and durability
