OSPW RS Alpha Pulley Wheel System for Campagnolo Super Record WRL - ALPHA Aluminum Pulley, Carbon Ca

The CeramicSpeed OSPW RS Alpha Pulley Wheel System brings precision performance and modern design to Campagnolo Super Record Wireless 12-speed drivetrains. Designed for riders who demand every watt of efficiency, this oversized pulley system combines advanced bearing protection, lightweight carbon construction, and a refined aesthetic that complements Campagnolo’s flagship wireless group.

At the heart of the system are Alpha Disc Pulley Wheels featuring ADR (Active Debris Remover) technology. This patent-pending design shields the bearings from contamination, maintaining smooth operation even in challenging conditions. Each pulley runs on Grade 3 Silicon Nitride ball bearings, which are significantly smoother, harder, and lighter than traditional steel bearings—translating directly to reduced friction and improved drivetrain efficiency.

The reinforced carbon fiber cage keeps weight to a minimum while offering exceptional durability and stiffness. Riders can fine-tune performance with three adjustable spring tension settings for perfect chain control across varying terrain. The narrow-wide composite tooth profile helps shed debris and ensures consistent chain engagement.
