CeramicSpeed OSPW RS Alpha for SRAM RED AXS (Black)

The CeramicSpeed OSPW RS Alpha for SRAM RED AXS (Black) is a high-end oversized pulley wheel system designed to elevate your drivetrain with CeramicSpeed’s latest RS cage design and durability-focused pulley technology. Built for riders who care about premium feel, clean aesthetics, and a refined performance experience, the OSPW RS Alpha modernises the iconic OSPW look with a sharper, more contemporary cage profile that integrates neatly with today’s aero road frames and SRAM AXS groupsets.

This RS generation isn’t just a styling refresh. The cage structure has been reinforced for increased strength and long-term durability, making it a popular upgrade for riders who train year-round, travel with their bike, or rack up high kilometres. It also brings a higher level of custom expression with multiple logo and pulley options across the RS range, letting you tailor the finish to your build.

ADR (Active Debris Remover): cleaner running in real riding conditions

A key technology in the OSPW RS platform is ADR (Active Debris Remover), a patent-pending feature engineered to keep contamination away from the bearing zone. The design uses a dust cover that locks into a groove in the pulley wheel to enclose the bearing area, paired with a bladed groove structure intended to actively push debris away as the pulley rotates. For Australian riding—where summer dust, wet winter grit, and mixed road debris are common—ADR is designed to support smoother long-term performance and reduce the kind of contamination that can shorten bearing life.

ALPHA Disc pulley wheels: added protection and durability

This Alpha version features CeramicSpeed’s ALPHA Disc pulley wheel concept, originally introduced on OSPW systems built for more demanding environments. The ALPHA Disc uses a two-piece design: a narrow-wide composite tooth profile intended to improve wear resistance and reduce noise, combined with a solid aluminium disc that helps prevent debris getting trapped inside the pulley structure. The solid disc approach was field-tested in severe cyclocross conditions, with sponsored team feedback highlighting improved mud clearance in harsh environments.

Ideal for premium builds and workshop drivetrain servicing

The OSPW RS Alpha is most commonly installed as part of a broader drivetrain service or performance upgrade—often alongside a new chain, cassette inspection, derailleur alignment checks, and a complete shifting tune. Riders in Brisbane and across Queensland frequently pair upgrades like this with professional workshop services to ensure correct setup and consistent shifting performance.
