Surly Karate Monkey 27.5″ Mountain Bike

Multipurpose Hardtail Mountain Bike

The Surly Karate Monkey 27.5″+ is a highly-versatile trail bike that also plays the part of 29er equally well if you BYO wheels.

This bike 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. Surly says 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. This allows you to pick your poison — provided your poison is having a really great time while permanently donning a big ‘ol grin, of course.

• Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork
