Steel vs Alloy — What to Consider
Steel sprockets outlast aluminium alternatives significantly, making them the preferred choice for riders prioritising durability and value over weight saving. The trade-off is slightly greater weight and rotational inertia compared to alloy sprockets.
Frequently Asked Questions
What chain pitch does this suit? This sprocket is designed for 520-pitch chains. Always confirm your existing chain pitch before purchasing.
Is steel better than alloy for rear sprockets? Steel offers superior wear resistance and longevity, making it the better choice for street and everyday riding. Alloy sprockets are lighter but wear faster.
Should I replace my chain and front sprocket at the same time? Yes. Replacing the full drivetrain together ensures even wear and maximises the service life of all components.
