weinmann type stems

Anybody know the formal name for these types of stems with the nut at the top, or if anyone makes a stem in this style still?

I've seen them called "spearpoint stem" or "lugged stem," but I'm not sure either term is widely used enough to be worth remembering.

They first appear in the 40's or so. Reynolds made one of that basic type, cast in aluminum. They are really modeled on hand-made stems brazed up from steel tubing; GB made them from both Reynolds 531 and Accles&Pollock Kromo tubing; and then, in the 50's, GB made a cast aluminum (hiduminium, actually) version that was based on the steel ones. Most aluminum stems from the 50's through to the early 70's were more or less of this style; brand names I've seen on them include GB, Reynolds, Pivo, AVA, Philippe, Compe, Jun, and... oh, I don't know, there were a lot of them.

Lugged stems, in a style similar to what you showed, but made for threadless type forks, are made today; they're steel, handmade, and expensive.

Looks to me like the OP's stem has a steel shaft -- the top looks yellowish, and the bottom looks like chrome.

interesting - and thanks for the details! I found a similar ttt that I am happy with at a swap meet today (guess there really were a lot of them, and not just the French...). I was specifically looking for one with the back end of the clamp sticking out slightly, and was provided .



I have seen the lugged stems you mentioned (Rivendell/Nitto ones?) though none seem to have the nut at the top or the extended top part in the back. Either way, my search is over - thanks for the help!
