I found out that these things crack when they get old, at least if they're made of plastic like the ones on my Bianchi are. My LBS had one Shimano piece, but they'll be going on a nine speed Campy Veloce crankset, so I'd like to keep it in the family, so to speak. I don't need über-expensive blingy things, just a set that looks right on a '90s Bianchi.

Thanks!
