FULL DESCRIPTION

Renthal Ultralite Rear Sprocket 520 Pitch 42 Tooth Silver

The Renthal Ultralite Rear Sprocket is engineered for superior performance in both road and road racing applications. Crafted from the same high-grade 7075 T6 aluminum used in their offroad sprockets, this sprocket offers exceptional durability and reduced weight.

Key Features:

Ultralite Design: Significantly reduces unsprung weight for improved acceleration and handling.
7075 T6 Aluminum Construction: Provides excellent strength-to-weight ratio for demanding use.
Hard Anodised Finish: A deep, integral surface coating that dramatically enhances hardness and wear resistance, ensuring extended lifespan.
CNC Machined: Precision manufactured for perfect fit and optimal chain engagement.
520 Pitch: Designed to work with 520 pitch chains.
42 Tooth Count: Provides a specific gear ratio for enhanced performance.
Silver Color: Offers a clean, high-performance aesthetic.

Renthal's hard anodising process is a critical element, creating a surface that stands up to the rigors of high-speed riding and frequent gear changes, offering increased longevity over standard sprockets.
