Surly quietly rolled out two new colors and builds for the Karate Monkey. Find details on the Toxic Tangerine Karate Monkey Sus, and the Wet Clay version with a rigid fork…

Posted by Logan Watts

Originally designed around 29″ wheels (and one of the OG frames that helped spur the 29er movement), Surly’s venerable Karate Monkey is now a 27.5+ rig with relatively modern, suspension corrected trail geometry, dropper post compatibility, Gnot-Boost rear spacing, thru-axles, and clearance for 29” x 2.5” or 27.5” x 3” tires. For 2020, there are two new colors and build options, a fully rigid, SX Eagle equipped “Wet Clay” version, and the “Toxic Tangerine” 140mm Rock Shox Gold RL suspension fork. Here are build kits, pics, and pricing for each. Also, be sure to check out Michael Dammer’s Karate Monkey in our Rider and Rig series, as well as Ben’s Reader’s Rig Dispatch to see how others are using this bike…
