Next-generation pulley wheels, designed to optimize transmission performance. Made with full-ceramic bearings (entirely ceramic), they ensure exceptional smoothness by reducing friction to an absolute minimum. The component is developed to run dry and requires no maintenance.

Installation and Maintenance:

Chain: It is not necessary to modify the chain length (the same number of links as the original configuration can be maintained). However, to ensure optimal performance, it is recommended to consider replacing the chain at the time of installation, depending on its wear condition.
Longevity and lubrication: The robust design features full-ceramic bearings protected by special aluminum covers, designed to maximize durability over time. The system operates entirely dry: no grease is required.
Cleaning: The composition is completely immune to oxidation. In case of debris or dirt buildup between the covers and bearings, a simple wash with water or degreaser is sufficient.
Important warning: NEVER apply any type of lubricant to the dry bearings.
