With our OSPW RS for Shimano Road groupsets, we're lifting the OSPW into the future with a distinctly modern and angular design. The updated design brings balance and refinement to the OSPW System allowing it to blend seamlessly into the contemporary design trends of bikes and groupsets - making up the whole of which the OSPW System is part.
With an added level of customization (multiple Logo and Pulley Wheel options) combined with new innovative tech features the OSPW RS meets consumer demands for personal expression and premium ride experience. The OSPW RS is a statement for where we've been, and where we're going - always at the forefront.
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.

Technologies:
- Alpha Disc: The Alpha Disc features a two-piece construction. A separate narrow-wide tooth profile produced in a composite material that offers prolonged wear protection and noise reduction. As well as a solid aluminum 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.
- Active Debris Remover (ADR): ADR is 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.
