Description
The CeramicSpeed Ceramic Alloy Derailleur Pulleys for Shimano 11-Speed are one of the simplest ways to reduce drivetrain friction — swap two components, and your rear derailleur runs measurably smoother on every pedal stroke. Built from alloy with CeramicSpeed bearings inside, these pulleys are designed to outlast standard OEM options while cutting the resistance that builds up where your chain changes direction most.
The narrow-wide 12-tooth profile helps reduce chain articulation and keeps engagement clean and consistent. Upper and lower pulleys are marked with directional arrows for straightforward installation, and each kit includes an alloy spacer kit and CeramicSpeed Oil to get you running correctly from the start.
