I know it's not very vintage, but I've gotta go with a threadless adapter.
I need the 21.1mm quill diameter size, and a 1 1/8" top size
It will go below a reversible V-O 17 degree stem, in the 120mm length, linked here: http://store.velo-orange.com/index.p...0-17-rise.html

My question is, does anyone make this item in an alloy? I'd like it to somewhat match the VO finish, I'd like the stem bolt to have a recessed allen head, and I'd like it to be longer than 6". (no comments, please...)

My search so far has been unproductive...

Any online suggestions or, if you have something in your box-o-stems, I'd gladly welcome a PM.

Thanks!
