With CeramicSpeed's OSPW RS for Shimano 105 7150 series groupsets, CeramicSpeed is 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 CeramicSpeed has been, and where CeramicSpeed is going - always at the forefront.
SHIFTING TIME
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.
Patented ADR technology has been developed in a constant pendulum between CeramicSpeed's R&D department, the CeramicSpeed test lab, and field testing conducted by a select group of CeramicSpeed's professional off-road teams.
ALPHA Disc
For CeramicSpeed's new OSPW RS, CeramicSpeed is offering versions fitted with the ultra-durable ALPHA Disc Pulley Wheel first introduced with CeramicSpeed's OSPW X for Eagle Transmission.
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.
The first iterations of CeramicSpeed's solid disc pulley wheel design were tested in the field during the CycloCross World Cups a couple of years ago. During the 2022 CycloCross season, CeramicSpeed's sponsored team Tormans used the solid disc design extensively and provided valuable feedback on its ability to provide mud clearance in the worst of conditions.
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.
