Quicker and faster engagement is what race hubs are all about these days. The fastest Spring & Pawl Engagement System in BMX!  The Quad Hub features 150 ratchet teeth which engage every 2.4 degrees so what you get it is a super fast engaging hub. 
 
We still provide 4 cog spacers which allow you to position the cog where it provides the best possible chain alignment.  Hubset comes with a 16t cog but is designed to work with any Shimano compatible cog and any Shimano type tool will remove the cog.
Fixed independent leaf spring/pawl system acting simultaneously when engaged
Less resistance and less wear = a smoother rotating hub
Axles are 10mm axles but with a 20mil front option also now available
