BMX Sprockets

What Role Does a Sprocket Play?

BMX sprockets are essential for generating forward movement on a BMX bicycle. They are an integral component of your bike’s drivetrain and influence the overall feel of your ride. Sprockets are available in various colour schemes and designs to allow you to customise your setup.

BMX bike sprockets are typically crafted from different types of aluminium or steel. Aluminium sprockets boast a high strength-to-weight ratio, whereas steel sprockets are sturdier, more cost-effective, but heavier. You may also want to consider a BMX sprocket guard, especially recommended for aggressive riders who frequently engage with rails or kerbs.

Which Sprocket Size Suits BMX Best?

The appropriate sprocket size depends on your riding style. Sprocket sizes for BMX are determined by the number of teeth they possess. For a Freestyle BMX bike, the typical front sprocket has between 25 and 28 teeth, although this can vary from 16 to 45. Most contemporary freestyle BMX bikes are equipped with a 25/9 gear ratio.

Adding more teeth to the front sprocket will increase the gear ratio. This alteration makes it more challenging to start moving, but it enables higher speeds and more power. Racing sprockets generally have more teeth, and a 44/16 ratio is a popular preference for many riders.
