To help some of the people working on bike restoration I am attaching information provide in several BSA service bulletins. Your wheel less tire is usually listed in the parts manual. Once you have it check for that number on BSA SB #79 May 1961. The rim offsets are listed. The spoke length and descriptions are listed on the BSA SB #714 revised Oct. 1957 The bike models that are hand listed were not verified completely. The ones I have used worked out for me. Good luck, Lloyd L
