RENTHAL SR4 120 BCD chainring

The Renthal SR4 chainrings are legendary in their stiffness and longevity. The 5mm thick Ultralite chainring uses an I-Beam section tooth support bed, 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.The SR4 120 features an offset tooth bed, which significantly improves chainline when switching from a double chainring set-up to a single ring. The chainring is also threaded to accept standard SRAM hardware, for ease of conversion.Renthal® SR4 chainrings are designed to ride faster, jump further and last longer. Features: - 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 - Threaded to accept standard SRAM hardware - Precision CNC machined to extremely tight tolerances - Single speed, 8, 9 and 10 speed compatible Specifications: - 120mm BCD (bolt circle diameter) - 7075 T6 aluminium - Hard anodised finish
