Promax have dropped a chainring that is possibly the most reasonably priced CNC machined chainring on the BMX race market. Manufactured from high-end aluminium, the Promax 4-bolt 104 BCD chainrings are designed to handle the torque and stress of modern BMX racing and are fully capable in other single speed applications.
These are a great upgrade for the club racer looking to change up the standard gearing on their race bike without breaking the bank, and without compromising quality.
