The Cema Ceramic Derailleur Pulley Wheels are designed to replace the original jockey wheels on compatible Shimano and SRAM rear derailleurs. Featuring CNC-machined aluminium pulley bodies and full ceramic bearings, they provide a low-friction alternative to conventional derailleur pulleys. Their precision construction supports smooth chain movement through the derailleur during pedalling and shifting.

Full Ceramic Bearings: The bearings use zirconium oxide ceramic balls and races, eliminating the need for conventional grease and contact seals. This construction minimises internal bearing friction while providing resistance to corrosion and wear. The ceramic components support smooth rotation and consistent performance during regular cycling.

Precision Pulley Construction: The CNC-machined aluminium bodies provide a durable structure for the guide and tension pulleys. Their tooth profiles are designed to maintain chain engagement and support accurate shifting across compatible road, gravel and mountain bike drivetrains. Replacing the original pulleys with this set allows riders to upgrade the derailleur's rotating components while retaining the existing derailleur assembly.
