      BMX Sprockets Buying Guide

      Browsing the market for BMX sprockets is a time consuming task as there are so many factors with sprockets that can get lost in translation, however in this guide we show relevant points to focus on for you and your riding style and what you should keep an eye out for in order to get the best out of your sprocket purchase!

      BMX Sprocket

      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.

      Bore

      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 BMX 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.

      Bash-guard

      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.

      Conclusion

      Final points to summarise are that there are many sprockets out there with different benefits for the type of riding style you ride with, although by following this guide it can give you a helping hand with purchasing the correct sprocket for your BMX!
