On a vintage Nuovo Record, any of you use the Shimano set with the Centeron pulley?
The 8sp Dura Ace duo match the old Brev. Int. or Italy in size. In my book, these DA ones represent the gold standard.
Unsure if the readily-available inexpensive versions utilize the same Centeron lateral movement.
Wondering if that lateral movement plays well with older 5 & 6 speed shifting.
At any rate, I just saw ten bucks shipped, on eBay, for the cheap ones. (Actually, $9ea for two sets.)
