Does anyone know the ERD of old Weinmann 2120 650B rims?
I scored a set of 650B wheels off an old Schwinn Mirada, and I'm thinking about rebuilding the rear with a cassette hub. I can't find any reference to the rim specs, and I guess I'll eventually have to measure the ERD myself, but it would be good to have a number to compare to my measurement. And I'd like to avoid removing the original Schwinn 40-584 tires - I can probably still ride them for awhile, but the gum sidewalls are a bit crackly.
