CeramicSpeedOSPW RS Alpha Disc for Shimano 9250/8150

The CeramicSpeed OSPW RS Alpha Disc Northern Lights edition brings a new level of technical sophistication and aesthetic flair to Shimano Dura-Ace 9250 and Ultegra 8150 drivetrains. This system features a modern, angular cage design that harmonises with the sleek, clean lines of the latest Shimano groupsets, providing a balanced and integrated look. The Northern Lights special edition finish adds a captivating iridescent glow to the drivetrain, inspired by the atmospheric beauty of the Arctic. Beyond its striking appearance, the oversized pulley design reduces chain wrap tension and friction, ensuring that your high-end Shimano setup operates with the maximum possible efficiency.

Patented Protection for Precision Bearings

To maintain its world-class smoothness, the OSPW RS system incorporates Active Debris Remover technology to shield its hand-built hybrid ceramic bearings. This system uses a unique bladed groove structure and a specialised dust cover to actively eject road grime, dust, and water as the pulleys rotate. By preventing contaminants from entering the internal housing, the ADR system ensures your bearings remain fast and silent over thousands of kilometres. This level of protection is essential for maintaining the crisp, lightning-fast shifting performance that Shimano Di2 users expect, even when riding in less-than-ideal weather conditions.

Reinforced Strength and Alpha Disc Technology

The structural integrity of the OSPW RS has been significantly upgraded with a reinforced cage that offers superior stiffness and durability compared to standard components. This rigidity ensures precise chain tracking and immediate response during gear changes under heavy sprinting or climbing loads. The system features solid Alpha Disc pulley wheels, which utilise a two-piece construction with a composite tooth profile for reduced noise and prolonged wear. By eliminating traditional spokes, the solid disc design prevents road debris from snagging, resulting in a robust, low-maintenance upgrade that enhances both the longevity and the performance of your premium road bike.
