Ok, so if you want a bmx wheel set (with out cassette) there are alot of choices, but the ones that really caught my eye are the Atomic Labratories Trail Pimp and Trail King wheel sets. These are incredible! Remember i am saying cassette-less wheels, if you were to get cassettes then by all means get the chris king hubs with some Alex or Sun rim, but otherwise i havent seen anything better than the atom lab wheels, they are insane for mtb too..
