Race Face Turbine Chainring 64 Bcd 24T

Race Face Turbine Chainring 64 BCD 24T. The Race Face Turbin chainring is the result of two years of engineering work and rigorous testing. Made from super stiff and lightweight 7075 aluminum alloy, the Turbine rings are made for performance and durability in even the worst conditions. An all new asymmetrical tooth profile allows for more upshift and downshift zones, for instantaneous, smooth and quiet shifting...even under load. The rings are also three times stiffer than previous rings, meaning that shifting is sharper and faster.
