Correct Bianchi parts?
I'm in the process of refurbishing an 84 Nuova/o Racing and I want to keep it as close to original if possible. Mine has a Suntour 13-21 on it but I don't think that's what they came with. Probably came with a Regina?
If Regina, which one?
It has a Sedis chain which I think might be correct.

It's Nuovo Racing.
My 1983 Campione D'Italia came with a Regina Oro freewheel. Regina Oro chain. Sedis would be period correct, but like the Suntour, may not have been original.

Original freewheel on my 1981 (probably 1982 model year) C D'Italia was as 13-23 standard 6-speed Regina America. Hubs and cranks were Ofmega, brakes were Modolo Speedy, and pedals and derailleurs were Campag. I moved the wheels to the 1959 Capo, which has a 38T inner chainring, and put a 14-26 SunTour freewheel on the Bianchi, with 50-42 up front.

I don't have the 1984 specs but the 1983 version was Regina Extra 6 speed, 14-24T while the 1985 version was Regina BX, 6 speed 14-24T. While the 1984 catalog pic shows what appears to be a 6 speed Regina EX, the ratio looks like 14-26T, if that's a concern. Bianchi spec'd Regina chains during this era, so a Regina Extra chain would almost certainly have been OEM. .

It is possible that a previous owner "upgraded" the chain from Regina to Sedis if the Sedis chain happens to be the "Sedisport" model, with the then, unque sideplates that was designed to better catch the cog teeth during shifting by having flared out middle sections. A feature seen in many modern chains these days. It was a common mod back then that was supposed to improve shifting performance.

The Sedisport chain was arguably the most popular aftermarket chain of the early 1980s. In addition to the bulged plates, it was also the first bushless roller chain. The inner plates had a flange that was formed as part of the hole punching operation. The roller rode on the flanges, eliminating the traditional bush. This made the chain more flexible, allowing it to shift better with derailleurs having a short gap and making it much quieter in operation. However, it also simplified manufacturing by eliminating the bush, making it less expensive.. It shifted well (with most derailleurs), was very strong, was the quietest chain on the market and was less expensive than other "quality" chains by ~10-15%. There was little not to like.

If the bike was used as a race/training bike, it probably had the chain replaced every 6 months or so. Chains are consumables.
