Multipurpose Hardtail Mountain Bike

The Surly Karate Monkey delivers a robust, lively ride on all types of rough terrain. Its frame is an incredibly versatile canvas for any dirty masterpiece your mind can conjure. According to the calculator (Thor), it can be built in about 487 different configurations. Originally designed as a 29er (and the frame that sparked the 29-inch wheel movement), the latest Karate Monkey is engineered to perform just as admirably as a 27.5+.
