Frame Quill Clamp
This tool is used to clamp a bicycle frame from the inside of the seat tube. The clamp tool can be installed into the frame and then into a bike stand or it can be left in the stand and the frame is slid up onto it and clamped in place. The tool can accept frames with seat tube inside diameters ranging from 26.6 mm to 27.4 mm. The top collar prevents frames from dropping from the bike stand.
