This custom Surly Karate Monkey is a steel hardtail built around a Medium Surly Karate Monkey frame in Peach Salmon Sundae with an upgraded Fox 34 suspension fork. The fork is very lightly used, but looks and functions like new. The bike features a Shimano Deore 12-speed drivetrain, Tektro Gemini hydraulic disc brakes, and 27.5 × 3.0" Surly Dirt Wizard tires on WTB ST i35 rims.

The Karate Monkey is a versatile mountain bike platform for trail riding, bikepacking, and mixed-terrain riding. This build uses high-volume 27.5 × 3.0" tires for additional traction and comfort on rough terrain.
