Description:

Engineered for ultimate drivetrain performance, the CeramicSpeed Oversized Pulley Wheel (OSPW) System for Shimano 9250 & 8150 Series delivers pro-level efficiency with striking design and unmatched durability. Featuring a Titanium Coated bearing upgrade, this OSPW system is built to handle the demands of high-performance road riding and racing.

Compatible with Shimano Dura-Ace 9250 and Ultegra 8150 12-speed electronic derailleurs, this system replaces the stock cage with a lightweight carbon-reinforced polyamide cage and oversized 13-tooth upper and 19-tooth lower pulley wheels. The result? Reduced friction, improved chain articulation, and longer-lasting components.

Key Features:

Titanium Coated Bearings: Premium CeramicSpeed bearings with a titanium coating for exceptional wear resistance, low friction, and extended longevity.

Oversized Pulleys: 13T upper and 19T lower wheels reduce chain articulation and drivetrain friction for enhanced efficiency.

Carbon-Reinforced Cage: Lightweight and robust for optimal shifting performance under high torque and load.

Compatible with Shimano 9250 & 8150: Specifically designed for Shimano Dura-Ace R9250 and Ultegra R8150 12-speed rear derailleurs.

Proven Watt Savings: Tested to reduce friction by up to 40% compared to standard pulley systems.

Long-Term Performance: Designed to deliver more drivetrain efficiency over time, even under harsh riding conditions.
