The 72mm is now available in 80a RACE Formula. The 72mm is a potent all-around wheel that can handle high speed drifts, but once broken in is a smooth sliding wheel that you can use for fast freeride. With tight lips and solid walls this wheel has a smooth slide and most any speed. Our race formula is stickier but 'thanes up nice once you break through the skin. This version will have more edge grip than the 75a Green SSF.
