Box One Quantum Drivers
Each Quantum driver is a full, one-piece chromoly driver supported by three large roller bearings. Inside the driver are six pawls, each with two teeth that engage a 60-tooth ratchet ring, which means the hub has just 6 degrees of engagement. Please note, these drivers are designed only for use with Quantums and are not compatible with other hubs.
