I just lost an eBay auction for a pair of Stronglight alloy chainrings for three arm cranks. I presume these would fit TA Professional, Campy three arm Grand Sport, the Stronglight equivalent, and maybe the Nervar three arm. Mostly, though, I was interested in some rings in useful sizes that would fit the old Stronglight cottered steel cranks.
Can anyone tell me if the alloy rings made for newer (i.e. 70's) alloy three arm cranks will fit the older cottered steel Stronglight and similar cottered steel cranks?
