Descriptions
Upgrade your drivetrain with the TOOPRE Ceramic Bearing Rear Derailleur Pulley Wheel, designed for smoother chain movement, improved shifting stability, and a lightweight riding experience.
This pulley wheel is made from CNC-machined aluminum alloy and features a metal bearing with ceramic balls for smooth, low-friction rotation. Compared with ordinary nylon pulley wheels, the metal ceramic bearing design provides better durability, higher transmission efficiency, and more stable long-term performance.
The TOOPRE pulley uses a circlip fixed structure, making it suitable for both guide pulley and tension pulley positions on compatible rear derailleurs. It is available in 11T and 13T sizes and comes with reducer sleeves for wider compatibility with different derailleur mounting shaft diameters.
With anodized color options and laser-marked branding, it not only improves drivetrain performance but also adds a stylish look to your bike.
