OSPW RS 5-Spoke for SRAM Force E1/Rival E1

The OSPW RS 5-Spoke is engineered for riders who prioritize raw efficiency and crisp shifting. This model introduces Further Drive Technology, which uses an updated tooth profile and cage geometry to optimize chain flow and reduce mechanical noise. It features high-grade aluminum 5-spoke pulleys paired with CeramicSpeed's handbuilt ceramic bearings. A standout feature is the Active Debris Remover (ADR), a patent-pending design that uses a bladed groove to dynamically fling mud and water away from the bearings while you ride, ensuring the system remains "clog-proof" even in adverse conditions.

Key Features

• RS (Racing Sport) Design: A reinforced, angular cage that provides superior shifting precision and resistance to chain torque.

   

• Active Debris Remover (ADR): Integrated bearing protection that extracts grit and water through centrifugal force during rotation.

   

• Further Drive Technology: Enhances the interface between the chain and pulley for quieter operation and reduced energy loss.

• Customizable Tension: Includes two spring tension settings, allowing you to tune the system for maximum watt savings or high-tension chain security.

   

• Handbuilt Ceramic Bearings: Standard with ceramic balls that are 58% lighter and significantly harder than steel, reducing drag by up to 40%.
