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 a shit-eating grin, of course.
Features:
- 100% Surly Chromoly steel frame, double-butted main triangle and 44mm headtube
- The tubeset uses Surly custom trumpet tubes for greater stiffness and durability
- Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142 and 148 x 12mm thru, as well as 135mm w/ 10/12 washer
- Clearance for 27.5 x 3 or 29 x 2.55″ tires
