Larry, Walt, and all CR inch-pitch-ophiles:

The chains are out there. Be aware, however, that Diamond apparently made a run of "repop" inch-by-three-sixteenths roller chain some time ago. These are commonly available NOS from the balloon folks for about $45-50 retail. They are a brownish color.

The original old top-end Diamond chains, which are magnificent IMHO, have blued inner links and nickel-plated outer links. These are understandably rather rare in NOS condition, and sell for considerably more. Be aware also that there were one-inch by one-quarter inch chains also IIRC - too wide for lightweight use.

My fave inch-pitch chain is the minimalist Wippermann block - anyone know of any NOS ones that are available for sale?

The Campy inch-pitch chainrings (available in 151 BCD only) are somewhat scarce in NOS condition but are available; usually 24, 25, and 26-tooth pop up on you-know-where from time to time. The C-brand rear sprockets seem to be the most rare from what I've seen, particularly in the larger sizes (you can generally find 6-tooth ones!! How's that for violating the fundamental law of gearing?!)

Walt, contact me off-list with your size preferences. I can probably dig through my stash and come up with a decent chain and cog for a reasonable price.
