What Our Gearhead(R) Experts Are Saying: "I've run the OSPW RS ALPHA on both Shimano and SRAM bikes, and the performance gains are instantly noticeable. Shifting feels crisp and precise, while the larger pulleys reduce drag and just make the drivetrain feel smoother. The ADR system is genius-it keeps grit out of the bearings even in sloppy conditions. Plus, the Niro finish looks incredible on modern builds."When we demand every watt counts, we turn to CeramicSpeed's OSPW RS ALPHA Niro Special Edition. Designed for both Shimano and SRAM's latest road groups, this oversized pulley wheel system combines sleek aesthetics with next-level drivetrain efficiency. The Niro finish pairs perfectly with the black ALPHA Disc pulleys, giving our bikes a bold, refined look that matches their cutting-edge performance. At the heart of the OSPW RS ALPHA is CeramicSpeed's Active Debris Remover (ADR) technology, a unique dust cover and bladed groove design that keeps bearings clean and spinning freely, even in gritty conditions. The ALPHA Disc pulleys feature a two-piece construction with a narrow-wide composite tooth profile for quiet, consistent engagement and an aluminum disc shield that blocks debris while adding strength. The reinforced cage provides new levels of durability, ensuring longevity through seasons of hard riding. The OSPW RS ALPHA Niro transforms drivetrain performance with customizable spring tension and buttery-smooth pulley rotation. Road, gravel, or cyclocross-this system blends modern design with CeramicSpeed's unmatched bearing technology to keep us pedaling faster, smoother, and longer.
