Ceramic Speed

Oversized Pulley Wheel Aero System for SRAM Red AXS/Force AXS - Coated Races, Alloy Pulley, Carbon C

CeramicSpeed's OSPW Aero system has been developed in close collaboration with one of the world''s leading aerodynamicists. The development process behind the OSPW Aero spanned over two years, where extensive wind tunnel testing influenced multiple design iterations. The end result is an entirely new cage structure wrapped around our existing mechanically optimized design.

• Coated bearing races increase bearing service life by increasing hardness of race and reducing corrosion
• Developed in coordination with Drag2Zero
• Features a 15-tooth upper and 19-tooth lower, aluminum pulley wheels with Grade 3 Silicon Nitride balls to provide absolute optimization of the rear derailleur
• Fits cassettes from 10 to 36-tooth
• Locally reduces drag by an average of 40% compared to stock derailleurs
• Not compatible with SRAM Rival AXS
• Only compatible with SRAM RED AXS and SRAM Force AXS
• Refines aerodynamics by focusing on frontal area impact, as well as smoothing and controlling the trailing wind
• Robust cage crafted from carbon reinforced polyamide for durability and light weight
• Two spring tension settings allow customized setup based on ride conditions
