CeramicSpeed OSPW RS Alpha Disc SRAM Red/Force AXS Pulley Wheels Argent Special Edition The OSPW RS Special Edition marks the first limited colour release of the RS platform. Argent delivers a clean silver finish paired with Silver ALPHA Disc Pulley Wheels with a distinctive graphic element that complements modern road bikes and groupsets. CeramicSpeed OSPW Modern RS Architecture The OSPW RS brings a sharp, angular design language that aligns with contemporary bike and drivetrain aesthetics. The reinforced moulded carbon fibre cage balances strength, durability and low weight, allowing the system to integrate seamlessly into the overall bike design rather than standing apart from it. CeramicSpeed OSPW ALPHA Disc Pulley Wheels The system is equipped with ultra durable ALPHA Disc Pulley Wheels. Their two piece construction combines a narrow wide composite tooth profile for reduced noise and extended wear with a solid aluminium disc that increases stiffness and prevents debris from lodging between spokes. This design was extensively proven in cyclocross racing under extreme mud conditions. CeramicSpeed OSPW Active Debris Remover Technology ADR is a patent pending bearing protection system designed to keep debris out of the pulley bearings. A sealed dust cover sits securely in a dedicated groove, fully enclosing the bearing, while a surrounding bladed groove structure actively ejects dirt as the pulley rotates. The result is long term durability and consistent performance in all conditions. CeramicSpeed OSPW Shifting Performance Optimised pulley geometry and low friction bearings deliver fast, precise and efficient shifting under load. The OSPW RS is engineered to maintain drivetrain efficiency while improving longevity in demanding real world riding. CeramicSpeed OSPW Compatibility and Build This Special Edition OSPW RS is fully compatible with the latest 2024 SRAM RED AXS road groupset. Like all CeramicSpeed OSPW systems, it is developed, designed and hand built in Denmark to the highest quality standards.
