Just to help everyone visualize this beauty---



Since only the frame is available with no fork, I'd say the sky's the limit.

But if you wanted to remain "stock" you'd need to source a 151 BCD Campagnolo Record crankset, Record FD & RD, the appropriate shifters, and Record pedals. It would have come with Weinmann centerpull calipers and levers, unless the original purchaser would have upgraded to the Campagnolo calipers and levers. A drop bolt would be needed for the rear caliper.

The wheels would have had Record high flange hubs most like laced to Mavic tubular rims. There is a chance the hubs would have been laced to 27" clincher rims. The freewheel would be a Regina Oro, 14-21 or 14-23 five speed. The stem and bars would be Cineli. A Record seat post, BB, and headset would round out the build with a Brooks Professional saddle.

You can see the challenge in sourcing all of these parts. Not easy. This is why I'd encourage you to build it with what you can find and then ride and enjoy it.
