CeramicSpeed OSPW Pulley Wheel Aero System for SRAM Red AXS/Force AXS - Coated Races Alloy Pulley Carbon Cage Black. CeramicSpeeds OSPW Aero system has been developed in close collaboration with one of the worlds 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.

Locally reduces drag by an average of 40% compared to stock derailleurs

Developed in coordination with Drag2Zero

Refines aerodynamics by focusing on frontal area impact as well as smoothing and controlling the trailing wind

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

Gaiola robusta fabricada em poliamida reforçada com carbono para maior durabilidade e leveza

Duas definições de tensão da mola permitem uma configuração personalizada com base nas condições de condução

Fits cassettes from 10 to 36-tooth

Coated bearing races increase bearing service life by increasing hardness of race and reducing corrosion

Compatível apenas com SRAM RED AXS e SRAM Force AXS

Not compatible with SRAM Rival AXS
