Surly Karate Monkey Bike 27.5" Fool's Gold 2021

(Size: Large)

Ready Stock


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.

Multipurpose Hardtail Mountain Bike.

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.

Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork.
Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though).
Clearance for 29” x 2.5” or 27.5” x 3” tires.
