Cyclami Derailleur Pulley 

The Cyclami Derailleur Pulley is a precision cycling drivetrain component designed to guide the chain smoothly through a compatible rear derailleur system. Cyclami pulley wheels are available in different tooth sizes and configurations, including ceramic-bearing options and oversized designs, so the correct variant should be selected according to the specific derailleur model and drivetrain setup. CNC-machined aluminium alloy construction provides a balance of low weight, rigidity and durability, while ceramic bearings support smooth pulley rotation and reduced friction. The pulley is suitable for performance-focused road, MTB and other compatible bicycle applications. Its precision tooth profile helps maintain stable chain engagement during gear changes, while an anodized finish on applicable models adds surface protection and a distinctive appearance. It is a practical choice for replacing worn derailleur jockey wheels or upgrading a compatible drivetrain setup.
