I need to find 2 correct size wheels for a 1972 Schwinn Varsity. If I stand a spoked wheel on it's bare rim, how tall should it be? I want original sizes so the original brakes work correct. I'll need to buy tires too.
Varsitys used 27 inch Schwinn S6 steel rims with 27 x 1 1/4 tires unless it is a child s Varsity. There were millions of them made. Might be the most common bike part out there. The ETRO number for the rim size is 630. Almost any bike COOP or bike flipper will have some. There will be many on E-Bay on any given day. Tires are still readily available and almost any bike shop in the world should have some. I just had a flood in my basement and threw out 20+ wheels like this last week. Roger
A bit more than 630mm as the bead seat is just below the top of the rim. No wheels even automobile are measured to the outside diameter of the rim. They are measured to where the tire sits on the rim. If you want I can convert the metric to inches but no one uses that number. If you want factory rims they were called 27x1 1/4 inch S-6 tubular straight sided rims. 630 mm equals 24.8 inches and that is where the tire sits. Approximately the inside diameter of the rim. I just measured a 1972 SS rim and to the inside if the rim it is about 24 3/4 inches and to the outside of the rim it is about 25 1/4 inches. Hard to measre as the hub is in the way. Roger
