Bicycle Mechanics - Early 90's Bianchi ready for current components?

A local seller has a steel frame Bianchi Eros for about $125. The frame appears to be in very good condition with only a couple of paint chips and no rust...not a thing of beauty, black with subdued decals. The owner says it was bought in 1991 and after a few months use wound up hanging in the garage. Sounds true given the bike's condition.

My question is would a bike that old have standardized dimensions to accept modern components? A friend is looking for a bike this size (63cm), but I don't want to steer him toward something that would require a scavanger hunt every time a repair has to be made. The components appear to be low end (Suntour Radius, Sakae gearing...say what?), and I'd be more confident recommending it if I knew replacements would be off the shelf components. Not to mention he may ask me to do some free wrenching...he's on a tight budget. If it were Celeste or had a 'Made in Italy' decal it would be an easier call (grinning).

The headset would probably be 1" threaded, and the rear spacing 126mm, or possiblty 130 mm, not exactly caveats, thererare ways to get around these things.
1" is a very popular size for threaded headsets/stems, so no problem there.
126 mm spacing can easily be spread, especially if the frame is steel to 130 mm to accept modern wheels.
Do it. It counds like agreat deal, especially bcecuse the Eros is/was a midlevel bike, and in almost new condition makes it all the better.
I can't think of any other parts standardization issues...
It would make a cool fixie project, if it has road horizontal dropouts, and if that's your thing! :D
Otherwise it would make a good commuting/entry level road/touring bike.

You can also find threadless headset stuff in 1", often on sale. That's the only real issue that I'd see with that bike. But, get a good headset and all's good. For that matter, King used to make a 1" headset, don't recall off hand if it was threadless or threaded, but he could buy one and that'd be it forever, most likely. And the Ritchey stems that I've bought in the last couple of years have come with a shim that lets them fit 1" steerers as well.

Unless the frame's got a lot of internal rust or something, it would be a fun project. I think that BB's are pretty standard, might wanna check to see if it's Italian or English threaded (I'd think Italian, but I've been very wrong before), but I think it would be a good one to get some miles on. I like the fixie idea, but it depends on your friend's inclinations.

What does all this babble have to do with anything?

Why does one need to get around a 1" threaded HS?

There's nothing 'outdated' about that frame. Any component it needs can be easily acquired.

stupid question, but somewhat relevant, as I have an early 90's bianchi mtn bike.

are bottom bracket threadings of that vintage still 'standard' and if not, readily available?

I would assume that your bianchi uses english, i.e today's standard for BB threading. I don't think that bianchi ever used italian threading for their MTBs.
So, you should be fine.

So, you should be fine.There is nothing non standard about Italian threading even if that's what it did happen to have. If it was made in the orient,it's english thread

Thanks for the information.
I told my friend that it's a solid frame that would suit the street/path riding he has in mind, and that this is not some handcrafted Italian masterpiece worth upgrading to a high end gruppo. It's a fun ride that will fit well for less than $200 even after tires, tubes and a chain. If infatuation becomes obsession (doesn't it always where bikes are concerned?) he can buy something nice later.
A fixed gear conversion would be a fun project, but isn't meant to be. This area is all 50mph descents and 10mph climbs.
