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
- 13-tooth upper and 19-tooth lower, aluminum pulley wheels with Grade 3 Silicon Nitride balls
- Robust cage crafted from polyamide and carbon fiber for durability and light weight
- Coated bearing races increase bearing service life by increasing hardness of race and reducing corrosion
- Compatible with Dura Ace 9200 and Ultegra 8100 series (Fits 11-30 and 11-34 Shimano 12spd Cassette options)
- Four spring tension settings allow customized setup based on ride conditions
- CeramicSpeed products with coated bearings include a lifetime warranty
- CeramicSpeed coated bearings include a lifetime warranty
