I got a 11.5cm that I can trade if required, it came with the bike its promax alloy with 38mm hight and possible 84degrees 4bolt front.
Are we talking
a) 1 1/8" threadless
b) 1" threadless
c) 1 1/8" threaded (25.4 quill) or
d) 1" threaded (22.2 quill)

I've mentioned it before - I bought some nice stems quite cheaply recently from
