Aluminium Alloy Oval Chainring for Road and Folding Bicycles 52T to 60T 110/130BCD

Replacing or upgrading the chainring on a road bike or folding bicycle requires a component that matches specific bolt patterns and drivetrain speeds. This aluminium alloy oval disk is designed for both 110mm and 130mm Bolt Circle Diameter (BCD) standards, making it a versatile option for many bikes. It accommodates 7, 8, 9, and 10 speed chains, so it suits a wide range of setups. Each chainring is CNC machined from aluminium alloy and treated with an anode anti-oxidation process. Tooth options from 52T to 60T allow you to tailor gear ratios to your riding preference.

Features and Construction

This chainring is built around practical engineering choices that enhance compatibility and durability over time. The oval shape is standard for highway riding applications, and the aluminium alloy material keeps weight low without sacrificing structural integrity.

Material and Build

The chainring is made from aluminium alloy and finished with CNC machining for precise tooth profiles. An anode anti-oxidation treatment provides a protective layer that resists surface corrosion from moisture and road conditions. The exact thickness or weight is not provided, but the combination of materials and processing is typical for performance-oriented bicycle chainrings.

Size and Practical Fit

This disk fits both 110mm and 130mm BCD crank sets, so it can be used on many road bikes and folding bicycles. It supports chains designed for 7, 8, 9, or 10 speeds. Tooth count options are 52T, 54T, 56T, 58T, and 60T, giving flexibility for riders who prefer lower gearing for climbing or higher gearing for flat speed.

Uses and Placement

This chainring is intended for installation on the front crankset of a bicycle. Its dual BCD compatibility increases the number of cranks it can fit, making it a convenient replacement part.

Event or Professional Use

For cycling mechanics or enthusiasts upgrading a bike before a race or long ride, this chainring offers a straightforward replacement that does not require specialised tooling beyond standard chainring bolts. The oval shape is commonly used in road cycling to smooth pedal stroke.

Everyday Home Use

Home mechanics maintaining a folding bike or road bike can install this chainring as a direct replacement for a worn or damaged original part. The wide tooth range lets you adjust the bike's character without replacing the entire crankset.

Benefits and Buying Value

The main advantage of this product is its combination of aluminium construction, CNC finishing, and anti-oxidation treatment at a competitive specification. It covers two common BCD sizes in one unit, reducing the need for multiple chainrings.

Reuse and Low Maintenance

The anode anti-oxidation treatment helps protect the aluminium surface from corrosion during normal use. Regular cleaning and lubrication of the chain will keep the chainring functioning as intended. No specialist care regime is required beyond standard bicycle drivetrain maintenance.

Why Choose This Product

This chainring is a practical, source-supported choice for anyone needing a road or folding bike chainring that fits both 110mm and 130mm BCD and works with 7-10 speed chains. The tooth range from 52T to 60T allows custom gearing. The CNC machining ensures accurate fit, and the anti-oxidation finish adds a layer of surface protection.
