SuperSprox CST-249-15-2 Front Chain Sprocket for 420 Chain, 15-Tooth Steel Design

The SuperSprox CST-249-15-2 front chain sprocket is engineered for durability and precision performance. Crafted from hardened SCM-435 steel, this sprocket offers exceptional strength and resistance to wear, ensuring long-lasting service in demanding conditions. The CNC-machined construction guarantees a perfect fit with smooth chain rotation, reducing drivetrain friction and enhancing overall efficiency. Fully recessed and drilled to minimize rotational mass, it contributes to improved acceleration and handling. Gas impregnated carburized teeth further enhance durability and help reduce chain drag, promoting smoother power transfer and extended chain life. The sprocket features grooved surfaces that prevent dirt buildup beneath the chain, which can otherwise accelerate wear and reduce lifespan. Designed specifically for 420 chains, this 15-tooth sprocket is an ideal upgrade for riders seeking reliable, high-performance drivetrain components. Whether for racing or everyday riding, the SuperSprox CST-249-15-2 combines toughness with precision engineering to deliver consistent performance and longevity.
