Renthal Twinring Aluminium Ultra-Light Self-Cleaning Hard Anodized HA - 520 SprocketRef : RT00098A / 1075635002

The RENTHAL Twinring Ultra-Light crown in hard anodized aluminum HA is designed for demanding riders seeking a balance between lightness and robustness. Its bi-component design combines a CNC-machined inner part made of 7075 T6 aluminum, as narrow as a classic crown, with a heat-treated hardened steel tooth to ensure the longevity of the tooth/structure connection.

• Type: Bi-component Twinring, mud-resistant
• Materials: Central part in 7075 T6 aluminum, tooth in steel
• Finish: Hard anodization HA, blue color
• Tooth: Nickel-plated hardened steel, pressed onto the crown
• Pitch: 520 — Teeth: 50
• Machining: High precision CNC

The slim profile and the tooth/structure assembly through pressing reduce the rotating mass without sacrificing the strength of the tooth. The hard anodization and mud-resistant design facilitate maintenance and grip on muddy terrains — a real asset for motocross and roadster practices. Suitable for 520 pitch transmissions and riders who want a lightweight, durable, and aesthetically pleasing crown.
