Surly Karate Monkey Bike

The Karate Monkey is a versatile hardtail designed for technical singletrack and backcountry exploration. Its progressive geometry and 140mm suspension fork make it capable on rough, rocky trails, while the steel frame offers the durability needed for bikepacking and long-distance riding.

The Gnot-Boost system is a unique Surly feature that allows you to use either 142mm or 148mm Boost rear hubs. This gives you more flexibility when choosing wheelsets or upgrading components down the road.

Yes, the frame is designed for versatility. While it comes with 27.5-inch wheels, the geometry is compatible with various tire and wheel setups, allowing you to customize the bike's handling and traction to suit your local trails.

Yes, the bike comes with internal routing for the dropper post, which keeps the cockpit clean and protected. It is a standard feature included to help you maintain better control and body position on steep descents and technical sections.

The chromoly steel frame provides a distinct, lively ride quality that naturally dampens trail chatter better than most aluminum frames. It is heavier than carbon, but it offers exceptional durability and a classic, compliant feel that many riders prefer for long days in the saddle.

Yes, the wheels are tubeless-ready. We recommend setting them up tubeless before your first ride to take full advantage of the lower tire pressures and increased puncture protection on the trail.
