Surly Karate Monkey 29er Trail Bike Frameset Black

The Karate Monkey frame has recently undergone an upgrade, featuring additions like internal dropper post routing, a new tubeset using the trumpet tubes from our Instigator 2.0, and a slightly adjusted, more progressive trail-focused geometry.

The frame includes a horizontal dropout with a derailleur hanger and Gnot-Boost spacing, allowing compatibility with various mountain bike hubs, including 10 x 135mm QR, 12 x 142, or 12 x 148 Boost™. The 44mm headtube provides broad fork compatibility, while the ED coating adds extra internal protection.

Whether you prefer wide tires or standard 29” wheels, the Karate Monkey adapts easily. Ready to tackle the trail head-on? The Karate Monkey is your ride.
