Just what we need - two entirely different cranks called "Professional". I need to check my adaptor/ring sets this evening, as I thought the rings were 6-bolt and therefore wouldn't fit the 151 Record cranks. I don't feel too bad for not knowing the TAs were 151, as I think I had asked Mike Kone and even he didn't think they were exactly 151.
Regards,
Jerry Moos
