Hi everyone. Old wheels have been stripped with only the hubs salvaged for rebuilding purposes. I'm going down the sm pro route and would like to order these direct so my question is can anyone tell me the correct sizes front and back to order and any code for the sm pro? Also what are the pros and cons of an 18 or 19 inch rear wheel? Finally just to be a pain tyre choice please any guidance on suitable overall sizes? Again thanks for any help guys,,, always appreciated

Mat, the SM Pro rims I put on my 1986 CR250 when it had a rear drum didn't fit correctly. The spokes would bend where they crossed. I've heard of this a couple of times before. It wasn't a problem when I changed it to a disc read hub. I heard of someone having their SM Pro rims re-drilled, thus changing the angle of the hole to fit a drum.
