What They Say... 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 smirk of satisfaction, 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) Clearance for 29" x 2.5" or 27.5" x 3" tyres At Surly we believe that the frame is the number one contributing factor to ride quality. So that’s the basket we put most of our eggs in. We’re not saying that fancy shifters and brakes aren’t great (we occasionally use them on our completes), we’re just saying that if your looking for a bike with the newest gadgets and gizmos mounted upon it, you’ll likely be happier looking elsewhere. If you’re looking for a frame that will be kick ass to ride, day in and day out for a long long time, then a Surly is where it’s at. Our enginerds spend their time making sure our framesets are the best ride out there; bar none. If you’re in it for the ride, then you’re in the right place.
