    Exactly what I needed to adapt my old Dad bike with a 21.1 mm quill stem to be able to use more modern stems and handlebars. Couldn't find many options out there for 21.1 quill stems.

    Perfect eBay transaction. Gives my old steel steed a new, more adjustable life. That’s a 1976 Schwinn Super Letour 12.2 the quill stem is going (actually already) on.
