Bath Outdoors Surly Karate Monkey - What we have to say:

We're long term fans of the Surly Karate Monkey. This is one of the most versatile steel hardtails out there and an iconic bike any cyclist would love to own. We have built this up as a rigid steel hardtail 27.5 plus tyre, Shimano 1x11 speed format. However, if you would like to modify the spec with a suspension fork, 29er wheels or anything else then please let us know and we can cost it up for you.

We have a couple of bikes built and ready to go in the shop, the remaining frames we have in stock are boxed up with build kits allocated to them allowing is to build and ship them in a couple of days.

We have used Shimano, Halo and Gusset components in the build as Shimano is built for UK riding, Halo Wheels roll like a dream but can take the hits with Gusset components adding style to the build. Halo and Gusset are also British companies which we're a fan of!

Any questions about this build? Feel free to email us or give us a call at the shop for more information or to chat through the build kit.

Please note: that we have used a stock photo for the Gold frame on the website. The Green and black frames in all of the photos are pictures of the actual build kits at the shop :).

This is what Surly have to say about the Karate Monkey:

Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. According to our computing machine (Thor) it can be set up in approximately 487 different configurations.

Originally designed as a 29er (and the frame that helped spark the 29” wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. This allows you to pick your poison — provided your poison is having a really great time while permanently donning a shit-eating grin, of course.

Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork
Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though)
