Surly Karate Monkey Frameset

The Karate Monkey is designed as a versatile trail hardtail. Its progressive geometry and steel frame make it a capable machine for technical singletrack, bikepacking, or aggressive all-day trail riding where durability and handling matter more than pure speed.

Yes, the frame is designed to be highly adaptable. While it comes optimized for 27.5-inch wheels, the geometry and clearance allow you to experiment with 29-inch wheels as well, depending on your preferred ride feel and terrain.

The Gnot-Boost spacing allows you to use either 142mm or 148mm Boost rear hub spacing. This gives you significant flexibility when sourcing wheels or upgrading components, as you aren't locked into a single axle standard.

Yes, the frame features internal routing specifically designed for dropper seatposts. This keeps your cockpit clean and protects the cable housing from trail debris.

The 4130 chromoly steel construction offers a distinct, damped ride quality that absorbs trail chatter better than most aluminum frames. While it is heavier than carbon, it provides exceptional durability and a 'lively' feel that many riders prefer for technical terrain.

No, this is a rigid frameset, meaning it includes a matching 4130 chromoly steel fork. If you prefer front suspension, the frame's geometry is suspension-corrected, so you can easily swap in a compatible suspension fork later.
