OSPW RS – Shifting Time

With the introduction of the Oversized Pulley Wheel system (OSPW) in 2015, CeramicSpeed has set standards in modern cycling. And with the Racing Sport (RS) models, the Danish-based manufacturer of high-quality hybrid bearings is once again at the forefront when it comes to taking the next step towards the future. A visibly updated design, innovative technical functions and more customization options are intended to provide a premium riding experience with the OSPW RS system, which combines the efficiency-enhancing properties of its predecessor with even greater balance and sophistication.

Active Debris Remover (ADR)

ADR is a patent-pending 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.

ADR has been developed in a constant pendulum between our R&D department, the CeramicSpeed test lab, and field testing conducted by a select group of our professional off-road teams.

New design: improved quality and strength

The new design for the OSPW RS isn't solely a visual update. The cage itself has been reinforced to offer new levels of strength and durability.
