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)
- Clearance for 29” x 2.5” or 27.5” x 3” tires
