All CeramicSpeed Bearings are hand-built in Denmark. Super-smooth CeramicSpeed grade 3 Silicone Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove.
The balls are held in place by a reinforced polyamide cage. Every bearing is optimized with a low-viscosity CeramicSpeed All Round Grease to minimize friction and increase bearing life. Non-contact seals complete the bearings, keeping dirt and moisture out. CeramicSpeed Bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cross, and MTB. The benefits are super low friction, better power transfer, and increased bearing life.
During the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads, and are 100% smoother.

SRAM's 1x Eagle component system boasts a twelve-speed cassette. We built pulleys that can handle the load better than stock. These CeramicSpeed Pulley Wheels work with less drag, adding to the power transmitted to the rear wheel while offering greater durability, going longer between replacement intervals.
These pulleys are also fully compatible with the SRAM Eagle AXS derailleur.
The aluminum pulleys with standard bearings are 34.4% more efficient than stock and use our low-drag, long-life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The upper and lower pulleys both have a narrow-wide tooth design with 14 teeth each. As the upper and lower pulleys have different tasks, they have different shapes. You'll find they are thus marked, and have directional arrows.
These pulleys should be installed with stock SRAM pulley spacers. Save those from your old pulleys before installing CeramicSpeed.
The kits come with CeramicSpeed Oil in a 15ml dropper bottle and grease in 5ml syringe. The bearings come pre-oiled. The grease can be used on the pulley bearings when riding in particularly harsh environments.
