Sold as a single set of 4 wheels
Blood Orange Jammers all come in at 82a hardness with an icey slide and easy kick out. The only difference then is the choice of sizes.
69mm for your longer hills, faster roll speed, and a little bit more speed carry in the straights.
66mm for you shorter hills, faster acceleration, for multiple slides on a hill, or longboard freestyle and dance.
60mm Street deck all terrain blasting wheels. You could probably still hit 30pmh on these, but their main jam is being able to get back to slide speed real fast.
