RIDERACE 13T Ceramic pully wheel

The Riderace ceramic 13T pulley wheel is a precision-engineered bicycle component designed to optimize rear derailleur performance and drivetrain efficiency. Featuring a lightweight, CNC-machined alloy body with an outer diameter of 41\text{ mm} and an inner diameter of 6\text{ mm}, it incorporates high-performance ceramic bearings to significantly reduce rotational friction and wear. With its 13-tooth configuration, this jockey wheel ensures smoother chain articulation, improved shifting precision, and enhanced durability for cyclists seeking a reliable upgrade

Key Features

• Optimized Tooth Count: The 13T configuration provides better chain wrapping, smoother articulation, and improved power transfer.
• Low-Friction Ceramic Bearings: Equipped with sealed ceramic bearings that significantly lower rotational friction compared to standard steel bearings.
• Lightweight Alloy Construction: Precision CNC-machined from durable aluminum alloy to maintain a rigid structure while keeping total weight to a minimum.
• Broad Compatibility: Engineered to fit a wide range of rear derailleurs, including major Shimano and SRAM systems, typically utilizing adapter bushings for 4mm, 5mm, and 6mm bolt sizes.
