I'm selling an excellent condition Hope 50mm stem. I bought a 50mm and a 60mm and the 60mm fit my setup a little better.

I used the stem for a 20min. ride and it's in great condition other than a few scrapes on the top from my LED light (see red arrows). A touch-up pen will fit it if it really bothers you.
