Aero-Optimized Oversized Pulley System for Pure Racing Speed

Description

The CeramicSpeed OSPW Aero Pulley Wheel for SRAM Red/Force AXS is engineered to be the fastest pulley system ever produced. Wind-tunnel testing shows a 40% friction reduction compared to stock derailleur pulleys, giving riders a measurable speed advantage in time trials and triathlons. Co-developed with renowned aerodynamicist Simon Smart, it delivers class-leading efficiency trusted by world champions.

Oversized Wheels for Optimal Efficiency: This system features a 15-tooth upper and 19-tooth lower pulley, designed to optimise chain articulation and reduce drivetrain resistance. The oversized aluminium pulleys ensure smoother rotation and more stable chain engagement, creating an ultra-efficient drivetrain feel during high-intensity racing and long-distance efforts.

Handbuilt CeramicSpeed Bearings: Each pulley wheel is equipped with handbuilt, coated CeramicSpeed Bearings for unmatched smoothness and longevity. These bearings offer extremely low rolling friction and enhanced durability, allowing riders to maintain top performance across thousands of kilometres. The coated races further reduce drag and extend bearing life under demanding conditions.

Customisable Tension and Wide Compatibility: The OSPW Aero system includes two spring-tension settings, allowing riders to fine-tune their setup for terrain or race style. It is compatible with SRAM Red and Force AXS derailleurs, including the 2020 11-speed Red eTap with clutch, as well as the latest Force AXS D2 models. This makes it a versatile upgrade for modern aero-focused drivetrains.

Chosen by elite athletes worldwide, the OSPW Aero system delivers the perfect combination of aerodynamics, durability and ultra-low friction for riders seeking every possible performance gain.

Features
  • Aero Co-Developed Design: Engineered with aerodynamic expertise for major drag reduction and maximum drivetrain efficiency during high-speed racing.
  • Oversized Pulley Efficiency: 15T upper and 19T lower aluminium pulleys improve chain articulation, cutting friction and boosting power transfer.
  • Coated Ceramic Bearings: Handbuilt pulleys use coated CeramicSpeed bearings for ultra-low rolling resistance and long-distance durability.
  • Custom Tension Settings: Two spring-tension modes let riders fine-tune shifting response based on terrain, race style, or drivetrain feel.
  • Wide AXS Compatibility: Works with SRAM Red/Force AXS systems, including 2020 Red eTap clutch derailleurs and newer Force AXS D2.
