Mike, Dave, et al,
Here's more info on Ambrosio - TTT
(from "All About Components, Part 3", Bike World magazine, August 1973)
"A current fad is for stems to pull tight with an allen key fitting at the top of the expander drawbolt, instead of a regular hexbolt. These usually fit 7mm hex key wrench. T.T.T. began this trend about 10 years ago (the company was known as Ambrosio then), with their "Gran Prix" model."
and
"The two most popular makes of alloy handlebars among present racers are Cinelli and T.T.T. (also sold as Ambrosio)."
Stem models available included Gran Prix, Record (very similar to Cinelli 1A), and Adjustable.
This answers a few questions... the company "TTT" of 1973 was known as "Ambrosio" 10 years earlier (1963), and "TTT" stems and bars were also sold as "Ambrosio" as late as 1973.
By 1978 the I-Pro catelogue only lists TTT "Record" stems, a close design to the Cinelli 1A.
Anyone else have further info?
