Quicker and faster engagement is what race hubs are all about these days. The fastest Spring & Pawl Engagement System in BMX!
Crupi Hubs are made in the USA and may take up to 3 weeks if not in stock.
The Quad Hub features 150 ratchet teeth which engage every 2.4 degrees so what you get it is a super fast engaging hub.
