OSPW RS ALPHA for Shimano 7150 Argent Special Edition

The Argent Special Edition is characterized by its silvery-grey cage finish and matching Silver ALPHA Disc Pulley Wheels. Unlike the standard version, which often features a black-on-black look, the Argent edition uses a distinct graphic element to highlight the modern, angular lines of the RS cage. It features a 13-tooth upper and 19-tooth lower pulley setup. The system is built with Active Debris Remover (ADR) technology and solid aluminum ALPHA discs to ensure the bearings remain protected from road grime and mud, making it equally capable for road, gravel, and cyclocross.

Key Features

• Argent Aesthetic: A unique silver-themed finish on both the cage and the solid disc pulleys for a premium, custom-build appearance.

• ALPHA Disc Technology: The solid aluminum disc design eliminates the "fan effect" of traditional spokes, increases lateral stiffness for faster shifts, and prevents debris from entering the pulley.

• Active Debris Remover (ADR): A patent-pending bladed groove system that dynamically extracts dust and moisture from the bearings as you peddle.

• Further Drive Technology: Optimized tooth profiles specifically designed for Shimano's 12-speed chains to reduce mechanical noise and vibration.

• Lifetime Warranty: Because the ADR technology is so effective at protecting the bearings, this system comes standard with handbuilt ceramic bearings backed by a lifetime warranty.
