Hey everyone. Have you replaced the S7 rims on a Schwinn Middleweight? (Typhoon, American, Heavy Duti, etc.) Can I go to a modern rim size and still use rim brakes? I have done a few conversions to 26" but I always used coaster/drum brakes. Recommendations for rim brakes that would work with a middleweight frame and 26" rims are appreciated. Thanks.
