OSPW X for SRAM Eagle Mechanical

The OSPW X for SRAM Eagle Mechanical is engineered to bring professional-grade efficiency to the XX1, X01, GX, and NX Eagle mechanical derailleurs. By replacing the standard 12-tooth pulleys with a 14-tooth upper and 18-tooth lower combination, this system reduces the chain's articulation angle, significantly lowering drivetrain drag. The cage is constructed from a lightweight, high-strength carbon-fiber-reinforced polyamide, ensuring that shifting remains crisp and reliable under heavy loads. Handbuilt in Denmark, this system is proven to reduce friction by 30-40% compared to the stock SRAM configuration.

Key Features

• Optimized Efficiency: Reduces overall drivetrain friction by 30-40%, providing a smoother pedaling feel and marginal gains on every climb.

• Narrow-Wide Tooth Profile: Both pulley wheels feature a specific narrow-wide design that mirrors the Eagle chain's architecture for secure chain retention in rough terrain.

• Custom Carbon Fiber Cage: A durable, stiff, and lightweight cage assembly designed to withstand the rigors of mountain biking while improving shifting precision.

• 3 Spring Tension Settings: Allows you to choose between lower tension (maximum watt savings) or higher tension (maximum chain security for aggressive trails).

• Wide Compatibility: One of the few CeramicSpeed OSPW systems that works across the entire mechanical Eagle range (XX1 down to NX).
