Bianchi Stelvio Questions

So I bought this Bianchi Stelvio. A few questions.

1. I don't see any online photos of one with chrome lugs...unless someone polished these. If so they did a good job. Did it come with chrome lugs?
2. What Campy copy crankset is this? It has no markings at all. Forgery?
3. Do these Mavic rims run 700c tires? I can't get Gatorskins on there and I dont have any 27" tires to try.

Thank you.

According to VeloBase.com that rim came in 3 different sizes, 650a, 700c, and 27"

Hopefully @Bianchigirll or another one of our resident Bianchi experts will be along soon to answer your questions.

The subject bicycle does look like a 1985 Stelvio with the exception of the lugs, fork crown and a derailleur set upgrade to 600 Ultegra, along with the usual rider preference change to saddle and pedals. As noted, the crankset matches the OEM spec Ofmega Brilliante. These were Bianchi branded with a silk/tampo lettering that easily wears off.

It should be fairly easy to confirm the model. The serial number should tell us the year and the seat post diameter should tell us if it's a match for the spec tubeset.

It's definitely a 1985 model, though the post size is one size larger than I was expecting. However, that could be due to over zealous reaming of the seat tube. Does it have five helical ridges inside the bottom of the fork's steeering column (see attached photo)?

No T-Mar. It doesn't have those ridges in the fork.

OK, that's even more evidence in favour of a Stelvio. During this period, the only Columbus tubesets that didn't utilize the steering column with the helical ridges were Aelle R, Aelle and Zeta. Bianchi didn't offer any Aelle or Zeta models in 1985, at least not in the USA market. The only other possibility would be the Allloro, which used Columbus in the main tubes but with a Falck fork.


The Alloro was a couple of steps up the hiearchy, so it doesn't make sense for the previous owner to purposely downgrade the model. Also, the inside of the steering column shows red paint, with the underside of the crown showing paint remnants in the crevices. To me, this suggests that red was the factory colour and that it has been selectively removed. The Stelvio was offered in red, while the Alloro was not.
