CyclingCeramic derailleur pulleys for Shimano GRX XTR 11 & 12-speed and SRAM XPLR MTB

Designed for demanding gravel and MTB drivetrains, the CyclingCeramic 14-tooth Narrow pulleys optimise the performance of Shimano GRX, XTR 11- and 12-speed groupsets, as well as SRAM XPLR and 12-speed MTB groupsets. Their specific narrow-wide design ensures optimal chain retention, even on rough terrain, for a more stable and efficient drivetrain.

Fitted with high-end ceramic bearings, these sprockets drastically reduce friction and improve pedalling smoothness. Gear changes become more precise, faster and quieter, even under heavy load or during technical sprints. Their optimised tooth profile ensures perfect chain guidance, minimising vibrations and energy loss.

Machined from aerospace-grade aluminium, they offer rigidity, lightness and durability. Each pulley is hand-assembled in France and undergoes individual quality control. The low-friction sealing system effectively protects the bearings against mud, dust and moisture, ensuring consistent performance whatever the riding conditions.
