I have for sale an unused stem. Technical parameters:
Steerer tube diameter - 31.8 mm.
Handlebar diameter - 25.4 mm.
Stem length - 105 mm.
Weight - 180 g.
Stem angle - unknown.
The stem is fully functional and has never been mounted on a bicycle. It has no hidden defects. The minimal, very shallow marks visible on the stem body are caused by years of storage. The stem looks much better in person than in the photos.
