The Karate Monkey Front Suspension bike features a Rock Shox 35 Gold RL A2 suspension fork with 140mm travel, and it’s paired with a dropper post out the box. Progressive trail geometry and Surly’s Gnot-Boost rear dropout system deliver a versatile bike with the ability to swap hubs and wheel sizes.

If you want to round-house kick some trail right in the face, the Karate Monkey is your sled.


Our inspiring review is coming soon, for now here is what 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. 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.
