ChroMoly alloyed steel is significantly stronger than materials used in other Cassettes including top-end OEM Cassettes and will last longer. The single block design offers 3D structure to optimize strength and distribute forces. This allows Prestacycle to remove more unnecessary material, making our cassettes lighter tha
