STEEL REAR SPROCKETS
• Manufactured using only the high-
est quality 1045 high-carbon steel
and most are heat treated for added
strength and wear resistance
• Computer designed weight reduction
holes are included where possible
• Most are zinc plated and some have
a baked-on durable paint process for
corrosion resistance
WORKS TRIPLESTAR REAR SPROCKETS
• Use only the highest quality aerospace grade 7075-T6 alumi-
num 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
