Reference: 1540-520-48GPRD — RENTHAL Twinring aluminum Ultra-Light mud-resistant hard anodized HA - 520

The RENTHAL Twinring combines lightness and robustness for demanding riders. Its inner part made of 7075 T6 aluminum, CNC machined with a flat profile as narrow as a classic sprocket, reduces mass without sacrificing geometry. The hardened steel teeth are hot-pressed onto the bi-component structure, providing increased wear resistance; the electrolytic nickel treatment enhances its protection against corrosion.

• Type: Bi-component Twinring (aluminum + steel teeth)
• Chain pitch: 520
• Number of teeth: 48
• Finish: Red hard anodization (mud-resistant)
• Machining: High precision CNC

Designed for enduro and roadster bolts, this sprocket facilitates mud evacuation thanks to its anti-clogging profile and is suitable for demanding use on wet or rough terrain.
