The guy I sold the Green Schwinn Twinn too had another rusty tandem he wanted to fix up for someone. He bought mine instead and was going to give me the old one, but now the person he gave the first one to wants a second for her other kids. Its pretty ratty. Anyways, my question is, the back rim was swapped out for an old Sears rim. Now I don't know how off brands were, but Schwinns had the heavy gauge spokes. This bike still has the original front rim but the tires shot. Anyways, my question is, will regular bike rims support the weight of 2 riders on a tandem? I know younger kids are going to be riding it, but I'd like it to be safe regardless. I don't really see a problem, just thought I'd ask and see what your guys opinions are.
