SRAM’s 1x Eagle component system boasts a twelve-speed cassette. We have 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, and greater durability, too, going longer between replacement intervals.

The upper and lower pulleys both have a narrow-wide tooth design. Both pulleys have 14 teeth.

When you go with these, you need to choose between four options. Machined aluminum pulleys with our CeramicSpeed Balls in stainless steel-races. These win efficiency tests everywhere, dominating the manufacturer’s pulleys. The second has aluminum pulleys with our CeramicSpeed Balls in Coated races. Third is machined titanium pulleys with our Standard Bearings. Fourth is machined titanium pulleys with our standard CeramicSpeed Balls installed in coated, hardened-steel races.
