CeramicSpeed Ceramic Alloy Derailleur Pulleys - SRAM 1-11 Speed Info
The CeramicSpeed Ceramic Alloy Derailleur Pulleys for SRAM 1-11 Speed were developed specifically to match the tooth profile demands of SRAM's 1x drivetrains — and then improve on the stock units in the areas that matter most: longevity and friction. The pulley bodies are CNC-machined aluminum with cutouts under the teeth for both mud clearance and weight reduction. Pressed into each pulley are CeramicSpeed's hybrid ceramic bearings — ceramic balls running in hardened steel races.
CeramicSpeed uses Grade 3 Silicon Nitride balls, which the company states are 400% smoother and 128% harder than standard steel balls, and 58% lighter. Compared to standard ceramic balls, they're over 100% smoother and 15% harder. The balls are assembled in dust-free clean rooms and verified before final assembly. The result is a bearing designed to last three to five times longer than conventional sealed units — and a set of pulleys that, in third-party friction testing, measured a frictional drag of just 0.033 watts. Installation requires only a 2.5mm Allen key; the existing SRAM spacers are reused, and the upper pulley's slightly narrower profile reduces the precision needed for centering.
