Product Description Especially flexible: The Karate Monkey Frameset by Surly You can ride the Surly Karate Monkey frameset with wide 27.5+ tyres or with normal 29" tyres, whichever you prefer. 27.5+ tyres have the same rolling diameter as a 29" wheel, but with the added traction and comfort of extra-wide tyres. That is just the beginning: Karate Monkey also features progressive, trail-oriented geometry and Gnot Boost Spacing. It allows you to ride the MTB hub of your choice, whether 10 x 135 mm QR, 12 x 142 mm or 12 x 148 mm Boost. The 44 mm head tube is compatible with many fork types, and you can also install an adjustable seatpost. Now go and hit the trail.

Colour Index:lemon lime soda:yellowManufacturer's Notice:When choosing your frame size you should take into account that Surly does not measure the seat tube specifications to the end of the seat tube. For frames with struts on the top tube, this is measured from the middle of the bottom bracket to above the struts. For frames without struts, measure from the middle of the bottom bracket to the top edge of the top tube.
