Hi I'm thinking about buying a wheelset that has CK ISO rear hub with QR-axle and I would like to change it to be used with fun bolts as I would be running it single speed on my Surly KM. Are the QR and fun bolts interchangeable? So can is just unscrew the QR adaptors from the axle and buy fun bolts from you and ride or do I need anything else? I've looked at the CK hub manual but I don't seem to find a crystal clear answer to this from anywhere.. cheers iiro

Hi Iiro - these bolts only work with the Heavy Duty Chris King axles. If the wheels have the HD axle with QR adaptors screwed in, you will be able to do this, but if they have the standard axle, it will not fit. The easiest way to tell is looking for the pinch bolt. If there is a concave end piece with four dimples in it is the standard axle - if there is a convex collar with a pinch bolt on the non-drive side, it is the Heavy Duty axle. Hope that helps! Thanks, Flipp.


Can you please tell me the overall length of this bolt, exclusive of the bolt head (threaded portion and shank)?

Hi Jacques - thanks for your question. The thread and shank comes to a total of 28.6mm (1 1/8"). Hope that helps! Thanks, Flipp.
