The 72mm Release allows you to let it all out. With a 42mm contact patch and radius edges, finding the release point has never been so easy. It's a "true" center-set wheel so it doesn't matter which way you put it on. At the heart of it all is the Crown Core. With three points and two valleys to separate the wheel into distinct sections, chatter and vibrations are eliminated. Made out of material 10x stronger then traditional cores, the Crown doesn't deform under weight maximizing your potential roll speed.
