There were some 1-1/8" quill stems used on MTB's back in the early '90's and I had one on a '92 Trek 7000 rigid fork, hardtail MTB. As Cross Creek noted, they weren't exactly a thing of beauty. AFAIK, there were no elegant, graceful 1-1/8" quills, at least I never saw one.

Maybe it's just me but I can't understand going to all that trouble and expense for a trivial thing like the "appearance" of a quill stem.
