Rear Sprocket Aluminum 38t 520 Yam

Features:

• Use only the highest quality aerospace grade 7075-T6 aluminum for high strength and light weight and computer designed weight reduction holes are included for even less weight
• Exclusive tooth-and-valley design gives you 24% more chain contact area for a better transfer of power to the rear wheel and a larger area to distribute the chain impact stress resulting in a virtually indestructible sprocket
• A hard anodized coating is applied to provide a super durable finish to an already great sprocket
