Surly Karate Monkey SS

Description

The Karate Monkey helped set the standard for 29er geometry. While its tucked-in rear wheel keeps it nimble and maneuverable, while here in its single speed configuration, its lack of shifting componentry keeps the bike simple — and the rider filled with a cathartic rage. 

The SS version is a good choice if you are looking to run your Karate Monkey as a 29er - it comes ready with Alex MD25 29" rims and a cassette ready freehub, to take your gears if you so with it.

Keep it stock for a rattle free riot of a ride, or use it as your base for customisation - gear it up for touring (the KM frame has braze-ons for racks, fenders and multiple bottle cages including fork mounts), or bikepacking with your choice of derailleur (1x or 2x) or gear hub.
