Ceramicspeed OSPW RS Alpha Northern Lights Edition

Taking its inspiration from their Nordic heritage, the dynamic colourway channels the stunning natural light phenomenon found in the cold north. The radiant surface adorns the ALPHA Disc Pulley Wheels featuring patented technology, ADR (Active Debris Remover), and hybrid ceramic bearings for an exceptionally durable performance. The Northern Lights design thereby adds a striking visual expression to these masterfully engineered pieces.

Patented ADR technology
Patented ADR technology is a technical feature that is based on a unique combination that makes it virtually impossible for debris to enter the bearing. It consists of a new dust cover design that sits safely anchored in a groove in the pulley wheel, thereby completely enclosing the bearing. This is paired with a bladed groove structure that surrounds the dust cover, which dynamically extracts debris from the pulley wheel when it's rotating.

ALPHA Disc
For the new OSPW RS, CeramicSpeed is offering versions fitted with the ultra-durable ALPHA Disc Pulley Wheel first introduced with the OSPW X for Eagle Transmission. The ALPHA Disc features a two-piece construction. A separate narrow-tooth profile is produced in a composite material that offers prolonged wear protection and noise reduction. As well as a solid aluminium disc that eliminates the potential of external objects getting stuck between the spokes of the pulley wheel, while adding strength and stiffness to the Pulley Wheel design.
