Ambrosio adjustable stem

I'll list this on here and was wondering what a fair price or trade value would be. What do you think?

They are valuable/sought after. The final year for the Ambrosio marked ones was 1964-65. After that they would have been marked Tecno Tubo Torino (3TTT). Italian term "regolabile."

Will be interested to read what the experts have to say regarding FMV.

I sold one in somewhat nicer condition (no rust/corrosion on the bolt) on ebay a a few years ago for around $170.

Thank you @juvela and @spudly. Great info.

Were these just for track bikes? Who needs to adjust all the time rather than simply change out? Seems like a weight penalty.

It's an "acquired taste" item, as they are frankly,......... kinda crude and fugly.....
But they could bring in a couple of hundred bucks if sold to the right persons..

lol. Definitly acquired taste. I think I found one in the "favorite stem" thread. I'm kinda liking the industrial stuff lately. Someone else was appreciating the slab-sided Triomphe RD, and I could see the appeal.

Stem looks better polished:

There is no specific track model of these, even though many refer to them as "track stems" (misnomer).

They are only made where the angle is ~72 degree, unlike a purpose made track stem which would have a more acute angle.

One thing they can be handy for is if a given mount has more than one rider.

They can also be an aid for sizing/fit (1950's "fitkit").

Adjustable stems with a sliding extension are often generically referred to as Major Taylor stems, after the famous TOC cyclist. I've read that he invented the style but I'm wondering if it's more a case of him having popularized them, being the most famous of the early proponents.

Regarding price, I have a project that could use one, so I've been following prices fairly closely for the past couple of years. The A&P I've been seeking typically go for $200-$250. The Ambrosio are typically under $200. Given the condition, I'd place this sample around $175.

I never got these sense they are a expensive track oriented stem that no serious track rider would use. That said in slightly rough condition it should fetch the insane price of $150-250. I would list at $80 starting with $200 buy it know price and see what happens..
