I've done a search and seen a few people in this thread riding fixed. . . I'm looking to buy a $500-$1K singlespeed/fixed gear, and was wondering if anyone could recommend one that will put up with a 6'3", 260 lb. guy with, I guess, pretty strong legs. Is there a best frame type? Perhaps more importantly, has anyone had good/bad experiences with any brands of wheels, cranks, etc.? BTW, I'm, um, one of those people who just tend to break stuff.
