I have three excellent used or NOS 54T Stronglight 107 chainrings. The 107 was perhaps the last of the classic Stronglight cranks, after they had switched to the Campy 144 BCD circle, ironically about the time Campy was abandoning this circle. Lots of people think this was one of the coolest Stronglight cranks ever made. 54T is too much for my old fart legs, so I'd like to trade for Stronglight 107 49T to 52T rings, or failing that any quality 49T to 51T classic rings, any marque or BCD.
