CeramicSpeed Ceramic Titanium Coated Derailleur Pulleys - SRAM 11 Speed

Every watt saved in your drivetrain is a watt that moves you forward — and the CeramicSpeed Ceramic Titanium Coated Derailleur Pulleys for SRAM 11-Speed are built to recover as many of those watts as possible. CNC-machined titanium bodies replace the aluminum or plastic of stock pulleys, running CeramicSpeed's Grade 3 Silicon Nitride ceramic hybrid bearings pressed into coated hardened steel races. The result is a pulley set designed to spin with dramatically less friction than standard offerings, while lasting significantly longer between service intervals.

The ceramic balls themselves are the core of the case. CeramicSpeed's Grade 3 Silicon Nitride balls are manufactured to tighter tolerances than standard steel balls — smoother surface finish, greater hardness, and lower mass — and they're assembled into races in clean-room conditions. The titanium pulley bodies add durability well beyond what alloy provides, with cut-outs beneath the teeth that clear debris and trim weight without compromising structure. These pulleys are designed to fit all 11-speed SRAM derailleurs directly.
