I've been looking at campy veloce and centaur compact UT cranks and it seems that they're the same with the centaurs having a better finish and different chainrings.
The veloce has exo drive and centaur has ultra drive chainrings and I was wondering what the difference in the two is. I'm guessing the centaur has a better finish, but how much more durable are the chainrings.
How much life can I expect from chainrings in general. Thanks!
