I think I am starting to get it.... Forget trying to find tires that fit these old rims. They are not to be had anymore.
This seems to be getting more complicated. Do I need to replace everything that is mounted on my back rim in order to upgrade to the hook type of rim? Cassette, bearings, hubs? Do I get new rims fully assembled? I'm sure what ever I get I won't be able to use my Suntour Cassette. What is the best way to approach this.
Thanks again,
