The new EVO derailleur pulleys are designed to optimize drivetrain performance. Developed with full-ceramic bearings, they guarantee exceptional smoothness by reducing friction to an absolute minimum and eliminating maintenance needs. They represent the ideal solution, as an alternative to oversized cage (CCD) systems, for a first bike upgrade and to experience the extreme fluidity of Nova Ride components.

Features and Innovations:

Optimized Performance: Thanks to the low friction coefficient of the 100% ceramic bearings, these pulleys ensure uncompromising performance, optimizing drivetrain smoothness and extending its service life.
Superior Durability: The combination of 7075 aluminum pulleys and full-ceramic bearings offers exceptional wear resistance over time. The system requires no lubricants or grease, is not subject to oxidation or rust, and is extremely easy to clean.
Quick Installation: The component is designed for fast mounting and intuitive adjustment, ensuring immediate integration without the need to modify the chain length.

Installation and Maintenance:

Chain: Installation does not require modifying the chain length (the same number of links as the original configuration can be maintained). To ensure maximum performance, however, 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 dedicated aluminum covers, designed to maximize lifespan and minimize concerns related to technical interventions. The system operates completely dry: no grease is required.
Cleaning: Thanks to the entirely ceramic composition, the bearings are totally immune to oxidation. In case of debris accumulation between the covers and bearings during use, a simple wash with water or degreaser is sufficient.
Important Warning: As these are bearings designed to run dry, NEVER apply any type of lubricant.
