ceramicspeed-oversized-pulley-wheel-aero-system-for-sram-red-axs-force-axs-coated-races-alloy-pulley-carbon-cage-black, 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 derailleursDeveloped in coordination with Drag2ZeroRefines aerodynamics by focusing on frontal area impact, as well as smoothing and controlling the trailing windFeatures a 15-tooth upper and 19-tooth lower, aluminum pulley wheels with Grade 3 Silicon Nitride balls to provide absolute optimization of the rear derailleurRobust cage crafted from carbon reinforced polyamide for durability and light weightTwo spring tension settings allow customized setup based on ride conditionsFits cassettes from 10 to 36-toothCoated bearing races increase bearing service life by increasing hardness of race and reducing corrosionOnly compatible with SRAM RED AXS and SRAM Force AXSNot compatible with SRAM Rival AXS
