Size small Karate Monkey frameset in Surly's "Hi-Viz Black." Call or email for availability on other sizes, and/or complete build options.*Bikes and frames are only available for in-store pickup.
With a frame and fork made of custom-designed Surly CroMoly “’Natch” steel, the Karate Monkey delivers a resilient, lively, durable ride. The Karate Monkey frame has recently been updated to include features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on our Instigator 2.0, and a slight tweak in geometry that is more progressive and trail oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger spaced to what we call Gnot-Boost spacing. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost™ will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection.
