Overview

About this bike

The venerable Karate Monkey. When it comes to mountain riding, this bike brings everything you need to the experience and more. It's shod with 27.5 x 3.00 terrain-clawing Dirt Wizards for max traction on singletrack thanks to an aggressive tread pattern and cushy, wide footprint. But there's more to this agile trail runner's set of shoes — thanks to generous frame clearance, you can drop a set of 29-inch wheels in with up to a 2.50-inch tire if you desire something with less bite and similar roll-over capabilities. And, with Surly's Gnot Boost rear dropout spacing, you can comfortably run any kind of mountain bike hub: 10 x 135mm QR, 12 x 142mm, or 12 x 148mm Boost will all work in the Karate Monkey frame. Wheel choices aside, Surly built the updated Karate Monkey with a nod toward modern trail-bike geometry and includes internal dropper post routing, two or three bottle mounts (depending on size), threaded fender eyelets, and all the braze-ons you've come to expect from Surly for attaching racks, cages, and bags galore. Running gear consists of SRAMS's rock-solid NX 1x11 drivetrain with full-length external housing and Level hydraulic disc brakes for reliability when you need it most. Throw on a 140mm suspension fork and this all-rounder turns into a serious trail slayer. For what seems like a simple bike at first glance, the Karate Monkey offers much, much more. Listen to the Monkey and lose yourself in its ways.
