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.
Crupi Hubs are made in the USA they may take up to 3 weeks to arrive if not in stock.
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.
