I currently have a KHS DJ50, and I have absolutely no clue what the hubs are. I need to replace my piece of crap RST fork, but I'm thinking about changing my 9mm quick release to a thru-axle, any size. All the forks I've been looking at are thru-axles. I've taken apart the hub, taken out the bearings and everything. I don't know how to measure the hole in the hub. I've heard of conversion kits, but I've also heard it doesn't work on certain hubs. If only I knew what those damn hubs were! Anyone have any suggestions on what I should do? Thanks in advance!
