I wrote several emails to the gentlemen from Japan several days ago but have not gotten a reply. I also passed the CR message from Chris Kulczycki on to a Canadian outfit (Bicycle Specialties) that handles new, NOS TA. I, for one, would sure hate to lose this new-found resource. I am ready to order about six rings if I'm not already too late.
