Renthal Ultra-light 520 front sprocket is precision CNC machined, nickel-chrome molybdenum steel, case hardened.
Renthal Ultra-light 520 rear sprocket is manufactured to close tolerances from 7075-T6 aluminum alloy, then hard anodized for wear resistance, durability, and a beautiful, high-quality finish.
The EK SRX2 gold chain features lightening holes in the inside plates, Quadra X-Ring seals, and a very nice gold finish on the inner and outer plates. The Quadra X-Ring seals are designed for reduced friction when compared to regular O-ring chains.
