I just went to install a NOS Sugino High Column Nut that I've been hoarding and discovered this particular one won't fit a standard 22.2mm diameter stem. Anyone know of a source for a Sugino High Column Nut to fit a 22.2mm stem?
Also, the NOS one I have fits a stem with a quill diameter of 21.15mm (according to the package). If anyone has a use for this feel free to make an offer.
