Renthal BMX chainwheel

Renthal BMX chainwheel


The Renthal SR4 chainrings are legendary in their stiffness and longevity. The Ultralite™ chainring is 5mm thick for super-stiff, direct power transefer. Weight is reduced to the absolute by removing all unnecessary material, for the highest possible stiffness at the lowest possible weight. CNC machined from 7075 T6 aluminium , the hard anodised surface treatment massively increases the lifespan of the chainring.

Renthal® Ultralite™ BMX chainrings are designed to ride faster, jump further and last longer.

• Computer aided Ultralite™ design enables the ultimate combination of strength and lightness
• High strength 7075-T6 aluminum alloy provides excellent durability
• Hard anodised surface coating for increased longevity
• Precision CNC machined to extremely tight tolerances
• Single speed speed compatible
