Manufacturer reference: 4454 42 C45T
The PBR crown made of C45T tempered and hardened steel is a final drive component designed for demanding riders. CNC machined and then subjected to quenching and induction hardening treatment on the tooth area, it aims to reinforce the part in direct contact with the chain for enhanced durability over time. Ideal for light road and off-road use, it is suitable for machines equipped with a 525 chain pitch.
Designed in collaboration with competition teams, this PBR crown is intended for roadsters and certain sporty trails where robustness and consistency of the rolling gear are essential. Its machining and heat treatment reduce localized wear on the teeth and contribute to a longevity suitable for long rides.
