The Crupi Quad Pro Rear Disc Brake BMX Hub features the quickest Spring and Pawl Engagement System around with 150 teeth engaging every 2.4 degrees. This type of consistent performance means less resistance and wear on your components and a hub that moves smoother for longer. These hubs require a 6-bolt rotor and Crupi recommends their adapter and 140mm rotor for newer Crupi frame models. All quality weighs in at just 14.95oz.
