kinda a random question, but having 6 s.a. 3speeds of my own and now having a shimano 333 3speed hub with coaster brake in it, i was wondering how well did these hubs hold up? vs s.a.? i got a 53 schwinn world that since i cannot build it up all original, i am gonna to possibly use much updated rims with the 333 hub to replace the old unmatching s.a. equipt set of wheels. i heard that they were sort of trouble some and being a 200lb rider, i don't want to do a build up with inferior hubs. and i have always had great luck with s.a. hubs and found them especially easy to rebuild. won't even try a shimano rebuild.
