These pulleys are made from glass fiber filled Delrin for low friction and quiet, long lasting performance. They both have a narrow/wide tooth profile for good chain meshing, retention, and shift performance.
The dust shields are designed to be filled with grease to protect the bearings from water and grit. For the best performance and longest life, it is good to periodically clean and re-fill the dust shields with grease, and wipe off all excess.

Two 14 tooth pulleys with bearings installed
Four dust shields
