Surly says.... Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. According to our computing machine (Thor) it can be set up in approximately 487 different configurations.

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. 27.5"+ tires have the same rolling diameter as a 29” wheel, yet you get all the traction and floatation benefits of extra-wide knobbies. And that’s just the tyres.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.

Bikemonger note.... Our Karate Monkey Bikes are UK specc'd and will differ from the complete bikes on the US Surly site.
