Bicycle stem wedge - for Tuf Neck and Pro Neck stems.
Material: 4130 chromoly steel
Finish: Black Oxide
Fork steer tube inner diameter size: 21.1mm
Threading:M10 x 1.0 (this is metric fine thread - NOT the original SAE threading of Tuf/Pro Neck stem wedges - it is meant to use with an Asian made hollow Potts Mod bolt)
NOTE: This is a stepped wedge. It will NOT fit a fully ramped quill.
ALSO NOTE: A M10 bolt may be slightly larger than the hole in your Tuf/Pro Neck stem. You should test an M10 bolt on your stem BEFORE buying.
