BMX Sprockets

What Role Does a Sprocket Play?

BMX sprockets are essential for generating forward movement on a BMX bicycle. As an integral component of your bike’s drivetrain, they significantly affect the riding experience. Sprockets are available in various colour schemes and styles, allowing you to personalise your setup.

Sprockets for BMX bikes are typically crafted from either aluminium variants or steel. Aluminium options offer a high strength to weight ratio, whereas steel versions are stronger, more economical, but also heavier. You might also want to consider a BMX sprocket guard, especially for riders who frequently engage in aggressive riding, such as grinding rails or curbs.

Which Sprocket Size Is Optimal for BMX?

The needed sprocket size is determined by your riding style. BMX sprocket sizes are defined by the number of teeth they possess. On a Freestyle BMX bike, the front sprocket typically features between 25 and 28 teeth, although this may range from 16 to 45. Most contemporary freestyle BMX bikes boast a 25/9 gear ratio.

A larger number of teeth on the front sprocket will lead to a higher gear ratio. This signifies a more challenging take-off, but enables you to attain higher speeds and exert greater power. Sprockets intended for racing often have more teeth, with a 44/16 ratio being a favoured option for many riders.
