OS20 Parts
If you've clicked on this page you're a definite deep BMX race fan, and you run the OS20 set up because you love the stability that the sightly bigger 451mm rim/tyre size gives you. OS simply stands for "over-sized" twenty inch wheels that some racers prefer for the above mentioned stability and the extra rolling diameter of the bigger wheel. Paired with specific OS frames, which have slightly longer rear ends to accomodate the larger diameter wheels, you can find forks in this collection that are slightly longer as well to provide the necessary tyre clearance. And it goes without saying that in this section you'll also find compatible tyres and tubes.
