CeramicSpeed OSPW Aero ALPHA v3 derailleur cage for SRAM Red D1/E1 + Force D1
The CeramicSpeed OSPW Aero ALPHA for SRAM RedD1/E1+ForceD1 v3 is an aerodynamically optimized oversized pulley wheel system that reduces drivetrain friction and increases power transfer efficiency. It is designed as an upgrade for road and triathlon bikes where riders seek every possible performance benefit.
The current V3 version features a redesigned cage interface for faster and more consistent mounting, while maintaining the high efficiency, aerodynamics, and durability of the entire system. Thanks to the combination of airflow-optimized shaping, top-tier bearings, and protective technology, it is also suitable for demanding conditions and intense racing use.
