I happened to be looking at rear sprockets and see that Drive Systems, once AFAM's US distributor, has next to no AFAM sprockets for sale and seems to be clearing out what little they have. A quick look at UK sellers shows the same thing. AFAM used to be the premier brand. AFAM.com maintains a brave face but their catalog is mainly about chains and just mentions sprockets in very general terms. I can't find any listings of sprocket part numbers for specific applications. Are they going out of business or otherwise getting out of making sprockets?
