Surly Karate Monkey Bike Gold 12 Speed Deore


Multipurpose Hardtail Mountain Bike

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. 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” tyres
