Time has crept up on me, and all of a sudden it's gotten very difficult to find 5-arm Hyperdrive C chainrings, for the handful of old bikes I maintain.
Anybody know where I can find them? Doesn't need to be vintage. Preferably someone who can ship internationally. Chainrings must be ramped and pinned like the Shimano ones.
I managed to get a full set of rings in decent condition from a FC M569 crankset I bought on fleabay, but not all sellers ship worldwide, and the shipping can be prohibitively expensive in some cases.
VueltaUSA seems to be still making them: SE Plus Chain Ring Black, 30 - 46T, Bolt Center Diameter: 94mm
Anybody used these rings before? Are they decently made?
