The Oversized Pulley Wheel (OSPW) RS (Racing Sport) represents the evolution of CeramicSpeed’s oversized pulley wheels, combining advanced technology, modern design, and maximum efficiency. This innovative system is the result of years of research and development, positioning itself at the forefront of drivetrain technology, designed to meet the needs of cyclists seeking a high-performance and exclusive riding experience.

Active Debris Remover (ADR) Technology

ADR is a patent-pending technology that prevents debris from entering the bearings, thanks to an innovative combination of:

• Sealed dust cover, perfectly anchored in the pulley to ensure complete protection.
• Bladed groove structure, which dynamically expels debris while the pulley is in motion.

This technology has been developed through rigorous lab testing and validated in the field by professional off-road teams.

ALPHA Disc Pulley – Maximum Durability and Performance

The OSPW RS is available with the ALPHA Disc pulley, first introduced with the OSPW X for Eagle Transmission.

• Narrow-wide tooth profile in composite material, ensuring increased wear protection and noise reduction.
• Solid aluminum disc, preventing foreign objects from getting lodged between the pulley spokes, enhancing stiffness and durability.

The first versions of this technology were tested during the Cyclocross World Cups, with Team Tormans providing crucial feedback on its ability to clear mud even in the most extreme conditions.
