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.
