Custom Karate Monkey

Multipurpose All-Mountain Bike

The Surly Karate Monkey exists to defy your expectations—and we've taken it to the next level! Our custom build in Loam Gold features a RockShox Pike suspension fork, making this monkey even more lively, capable, and ready to tackle your summer adventures.

Throw labels at this bike—bikepacking, mountain bike—they all stick. The Karate Monkey is patient when it needs to be and aggressive where it counts. Now equipped with a dropper post and grippy yet fast-rolling Vittoria Mezcal tyres, it’s ready to conquer trails, carry gear, and handle whatever the wild throws your way.

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. This allows you to pick your poison—bikepacking or mountain biking.

Modern Trail Standards:

• Dropper post compatibility (now featuring an SDG Tellis dropper post)
• 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.
