Karate Monkey Complete
The Karate Monkey is a 29" mountain bike. We sell it as a single speed, but the frame is highly versatile, capable of running derailleured gear systems, single speed, dingle speed, and fixed gear, and it can run disc or rim brakes. The frame is made from custom drawn double butted TIG welded Surly 4130 cromoly steel tubing and has clearance for tires up to 2.55".
The parts we chose work well, they're durable, and they look good too. And see that seat tube? It tucks the wheel in under you so the thing rips on twisty stuff, and the big footprint of the 2.3" tires hold your line. Good value, great ride. Get some.
Colors: Chum Bucket Red, Pitch Black
