Ceramicspeed OSPW System For Sram Red/Force AXS Coated/BLack 15+19T

Pure Efficiency. Proven Speed. Danish Precision.

Developed, designed, and hand-crafted entirely in Denmark, the CeramicSpeed OSPW System for SRAM AXS represents a major technological leap in drivetrain efficiency. Built with uncompromising attention to detail, this Oversized Pulley Wheel System delivers exceptional friction reduction, extended durability, and a measurable competitive advantage for riders seeking every available watt.

Using the highest-quality materials and CeramicSpeed’s signature oversized architecture, the OSPW System unlocks up to 40% lower friction compared to stock pulleys—translating to watt savings starting at 1.6 watts. Inside each pulley lies our world-class CeramicSpeed bearings, engineered to last 3–5 times longer than standard alternatives. The result is a smoother, quieter, and more efficient drivetrain built for road and triathlon performance at the highest level.

The system is compatible with both short cage and WiFli eTap AXS rear derailleurs cages, supporting cassettes up to 32T. Designed exclusively for 12-speed SRAM eTap AXS, it is not compatible with 11-speed systems.
