Re:
I like the ATAC very much, but it had only one position, slammed to the bottom. Otherwise it would show the quill part, much thinner than the rest, which looked terrible.
Nobody mentions the Zoom stems, quite in fashion in the early 90s as a cheap "upgrade" with its fancy titanium-like color... Kalloy-Uno was another popular poor-cyclist upgrade, in millions of anodizing varieties, and with matching handlebars, seatposts and barends.
In Germany quill stems are still quite popular on the hybrid-urban market, since they are much easier to slide up and down, useful for everyday cycling.
