i actually found the stand out at the curb as trash. I remember these stands from back in the 1970’s. They were sold through an ad in the back of bicycling magazine and it was either Steve’s Cycle Center on Salem Avenue in Dayton or International Pro Bike Shop in the back of Kettering Bike Shop that distributed them. There were 2 models - a basic model with a rubber coated hook that clamped the down tube over a cradle and the “deluxe” one you see here that clamped with a foot pedal that clamps or releases pressure on the hook when you step on the foot pedal. I think these used to sell for between 60 and 90$ BITD.
