SKU: CN515B

The Z42 525-pitch sprocket is the ideal choice for riders looking for a perfectly balanced final drive ratio between acceleration and top speed, delivering responsive yet controlled performance both on the road and on track.

With 42 teeth, it offers an excellent technical compromise for improving traction out of corners without excessively sacrificing maximum speed. This setup is highly appreciated in sport-oriented builds where precision and smooth power delivery make the difference.

Machined from solid Ergal 7075 T6, a high-strength aerospace-grade aluminum alloy, and finished with deep hard anodizing, it ensures long-term durability, wear resistance, and structural stability even under heavy mechanical stress.

High-precision CNC machining guarantees perfect concentricity, reduced unsprung mass, and more direct, efficient power transmission.
