Why choose an aluminum chainring ?

Aluminum is the preferred material for most modern road bike chainrings thanks to its excellent balance of strength and weight. It offers several advantages:

• Lightweight construction

• Excellent stiffness for efficient power transfer

• High corrosion resistance

• Long service life with proper maintenance

At only 33 grams, this chainring helps keep your bike light while maintaining dependable performance.

Compatibility

This chainring is compatible with cranksets featuring:

• 9-speed drivetrains

• Triple chainring configuration

• 5-bolt mounting pattern

• 80 mm BCD (Bolt Circle Diameter)

• Inner chainring position

Please check your crankset specifications or measure the bolt circle diameter before ordering to ensure proper fitment.

A cost-effective replacement

Replacing only the worn chainring is often much more economical than replacing the entire crankset. If your crank arms are still in good condition, this 30-tooth inner chainring is an affordable way to restore smooth shifting and reliable drivetrain performance.

Installation is straightforward using the appropriate tools, allowing you to extend the life of your existing crankset without the expense of a complete replacement.
