Find a freestyle BMX sprocket with the right amount of teeth

BMX Sprockets are required to create forward motion on a BMX bike. How much speed you can get, is determined by how many teeth you have on the front sprocket. Larger front sprocket gives more speed, but requires more power to pedal. On a Freestyle BMX Bike the most common number of teeth on the front sprocket are between 25-28.

On a Freestyle BMX the sprockets can be mounted with a bolt. This is known as a bolt-drive. Some sprockets are mounted on a spline-compatible crank. Sprockets mounted on a spline-compatible crank allows more torque than bolt-drive. The reason is that the spline gives about 48 contact points between the sprocket and the crank opposed to the one offered in a bolt-drive.

A sprocket with 48 contact points might sound like the obvious choice, but a lot of Freestyle BMX riders prefer a bolt-drive mounted sprocket, since it actually gives the rider the ability to tighten the sprockets.

We have a wide variety of different sprockets that are compatible with both bolt-drive and spline-compatible cranks. These are delivered with a adapter for the purpose. Read more about this under the specific product description.

To guard the BMX sprockets or not to guard?

If you are a very aggressive rider who regularly bites the rail or pavement, you might want to consider one of our guarded sprockets.

We have a few guarded sprocket that comes with a extra layer of protection, since a piece of metal protects the teeth, and therefore and in many cases expands the lifetime of the sprocket. A bit more expensive for sure, but it only takes one unfortunate crash and the extra money will be well spent.
