CeramicSpeed Uncoated Ceramic-Alloy Derailleur Pulleys for SRAM Eagle 12/14-Speed

Description

The CeramicSpeed Ceramic Alloy Derailleur Pulleys for SRAM Eagle 12-Speed are a direct swap for your stock jockey wheels — swapping in Grade 3 Silicon Nitride ceramic balls running in hardened steel races, housed in an anodized aluminum body. The result is a measurable reduction in drivetrain friction that you feel in the pedals on every ride.

Each pulley runs 14 teeth with a narrow-wide tooth profile designed to engage SRAM Eagle 12-speed chain precisely. CeramicSpeed’s own testing puts the efficiency gain at 34.4% over stock pulleys — a figure derived from their standard uncoated bearing configuration. The ceramic balls themselves are tested to be smoother, harder, and lighter than both standard steel and conventional ceramic alternatives, and they’re assembled in dust-free clean rooms before a final quality check. Available in Black or Gold anodized finish.
