Sulry Karate Monkey Steel Frameset Description:

The Surly Karate Monkey was one of the first production 29ers. Modern updates now feature a progressive trail geometry and Surly’s Gnot-Boost rear dropout system, meaning it can accept most axle standards on the market. Many riders choose to set up the Karate Monkey as a highly versatile 27.5+ mountain or bike-packing bike. Multiple mounting points are sprinkled throughout the frame and fork to maximize carrying capacity. Enjoy the freedom of creative thinking and build it up however you want.
