Surly KARATE MONKEY - 27,5"+/29" MTB Frameset - 2025 - hi-viz black

Choose your trail and ride it.

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 Surly 's 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.

Frameset with fork, seat clamp and thru axles.
