Sprocket Teeth

The amount of teeth on the sprocket should be coordinated with the amount of teeth on the rear hub to achieve the riders ideal gear ratio. If you’re going to change the sprocket with a different amount of teeth, you’ll need to change the amount of teeth on the rear hub as well to maintain the same feel/tension on the chain. A smaller sprocket will create more acceleration whereas, larger one will create more top speed.


The Bore refers to the hole in the sprocket where the spindle goes through for the cranks, it is important to coordinate the spindle with the sprocket bore size

How to mount sprockets onto cranks

Sprockets are fitted onto cranks in two different ways they’re either bolted to the crank arm or pressed on using the spline drive or sprocket drive system. It is important to coordinate the sprocket and cranks as not everything is compatible.


Some BMX sprockets either allow or have a built on bash guard, which is an additional piece of material that hangs past the chain to create a protective layer. So instead of hitting your chain, you hit your guard preventing the chain from breaking incase you jump or fall off a grind.
