I've never put hundreds of miles on one of them but I have put 50-60 on a few of them on different occasions and never had an issue.. I have a buddy that has the real thing, the Tioga, and he rode one of these and said they are not as nice of course, but descent...

Wonder if you got a lemon? Of if I have not put enough miles on one?

At any rate, the look and the price make them great for flip bikes that need the 'racing' look!!
