Spitfire Formula Four OG Classic Skateboard Wheels - white/orange (99d)
OG shape ( basically conical full)and graphic but with the upgraded Formula four , the 99 is great but it would be nice to get these in 101 too for the extra slide abilities

Spitfire Formula Four OG Classic Skateboard Wheels - white/green (99d)
Ordered the 55. Thought they would be too big. (Usually skate 53/54 conicals.) the 55 OG’s looked huge. Returned and got 52’s now these look small. Haven’t used them yet. Probably let my son ride them, he does skate 52mm wheels. Also wish they came in a 101 option. But I like F4 wheels in both durometer.
