Check out the chainring archive on the same site. They've got old Campy, Dura Ace, T.A., Stronglight (my old crank), Suntour Superbe Pro (my current crank), a gorgeous Colnago. Also some really funky stuff, like a spoked spider, a 10-armed spider, a front freewheel, and cranks with bent arms. But don't look at the guy with a chainring coming out of his head (that gross!).
