One of the things I frequently search for on Eboy is TA crank items. I have a set of TA arms that I've been riding since '71, they have about a zillion miles on them (try that with your campy records) and have seen with my own eyes the weirdest of all TA chainrings, the 130 tooth monster hanging in Mike Barry's shop that is a replica of Meiffret's world record hardware.
But what's the story on these ? I heard that the inner reinforcing web was meant for the center ring on a tandem ?
