Renthal 409U-530-41P-HA Ultralight Rear Sprocket Pitch Hard Anodized Sprockets - 530 41T

The Renthal 409U-530-41P-HA Ultralight Rear Sprocket is a 41-tooth, 530-pitch chainwheel engineered for serious street, track day, and road riders who demand race-proven performance and minimal unsprung weight. CNC machined to extremely tight tolerances from high-strength 7075-T6 aluminum alloy, this sprocket delivers a significant weight reduction—66% lighter than a comparable steel sprocket—without sacrificing durability.

Key Features:

• 7075-T6 Aluminum Construction: The same premium alloy used in Renthal's off-road chainwheels, providing an exceptional strength-to-weight ratio
• Hard Anodized Finish: An integral surface coating that significantly increases surface hardness and wear resistance for extended sprocket life
• Advanced Tooth Profile: Computer-engineered tooth geometry ensures precise concentricity, accurate fitment, and optimal load dispersion for maximum power transfer
• Self-Cleaning Mud Grooves: Grooves between every tooth on both sides help prevent dirt and debris buildup, maintaining consistent chain engagement
• Race-Proven Design: The Renthal Ultralight rear chainwheel is the choice of more factory race teams than any competing brand, trusted across World Superbike and National Superbike paddocks
• 530 Pitch / 41 Teeth: Designed as a direct-fit 530-pitch rear sprocket for compatible motorcycle applications

Renthal's combination of a high-strength base material and an exceptionally hard-wearing anodized surface treatment results in significantly longer chainwheel life compared to standard aluminum sprockets. The 409U-530-41P-HA is an ideal performance upgrade for street riders and track day enthusiasts looking to reduce rotating unsprung mass and improve drivetrain responsiveness.
