PRODUCT DETAILS
All new for 2025, Crupi's Quad CL hub sets. Featuring an all new shape. CenterLock hubs are a major advancement in BMX hub technology making these hubs more universal. All Crupi Quad CenterLock hubs will feature the CenterLock spline mount so these hubs can be used with or without a disc brake rotor. For those who want to move up to Disc brakes, you just need to add a CenterLock rotor or adapter to your hub and you are good to go!
- Easier, quicker and a more secure disc rotor installation. CenterLock hubs utilize a single lockring to secure the rotor, making installation and removal much faster and simpler than fumbling with multiple 6-bolt screws. The single lockring provides a strong and secure interface between the rotor and hub.
- 28H rear hubs now come with 6mm Allen screws so tensioner spacers are no longer needed and they fit beautifully into frames with enclosed dropouts.
-
No change in the engagement system. Potentially the fastest Spring & Pawl Engagement System and least amount of drag in the BMX industry! The Quad CL Hub features 150 ratchet teeth which engage every 2.4 degrees so what you get it is a super-fast engaging hub. (You won't know it's not instant engagement!)
-
We provide 4 cog spacers which allow you to position the cog where it provides the best possible chain alignment. Hub set comes with a 16t cog but is designed to work with any Shimano compatible cog.
- For 2025 2.0 Crupi frames and newer, use the Crupi Disc Adapter kit with the 120mm rotor. For 2024 and older Crupi frames, we recommend the Elevn Disc adapter kit with a 120mm rotor
- 28H set weighs 16.6oz
