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.
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
Coated bearings for longer lasting wear
Robust cage crafted from carbon reinforced polyamide for durability and light weight
Two spring tension settings allow customized setup based on ride conditions
