Elevate your electronic shifting performance with the CeramicSpeed OSPW RS Alpha Disc System V2. Purpose-built for high-level road and gravel competition, this revised V2 system provides precise seamless setup for modern SRAM RED D1/E1 and Force D1 12-speed AXS rear derailleurs.

Featuring an injection-molded carbon-reinforced cage and hand-built hybrid ceramic bearings, the 15/19-tooth oversize setup significantly diminishes chain articulation friction. Driven by FURTHER DRIVE Technology, it incorporates the Alpha Disc design—a solid aluminium core that prevents debris jamming paired with composite Narrow/Wide teeth for ultra-quiet operation. Reinforced by the patent-pending Active Debris Remover (ADR) seals, this drivetrain upgrade is protected by CeramicSpeed's official Lifetime Warranty.



Highlights

V2 Extended Compatibility: Fully optimized to fit SRAM RED (RD-RED-E1-D1) and Force (RD-FRC-D1) 12-speed rear derailleurs.
 
Alpha Disc Debris Prevention: Solid aluminium disc structure eliminates object jamming, while durable composite teeth dampen drivetrain noise.

Active Debris Remover (ADR): Patent-pending groove dust cover encloses the bearing to prevent dirt ingress.

Handmade Ceramic Hybrid Bearings: Crafted with premium ceramic balls inside stainless steel races for lowest drivetrain drag.

2-Stage Adjustable Spring Tension: Carbon polyamide cage allows customized chain tension adjustments suited to your riding conditions.
