OS20 Race Frames

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.

There's not a huge offering in OS20 race frames, but if they are available here in Oz, then we have them listed here. The OS20 frames have slightly longer rear ends to accomodate the larger diameter wheels and while there are some standard Pro frames that will fit the OS20 wheel/tyre package, by running a bigger wheel on a standard pro frames can force your bottom bracket up too high, leading to a funky handling race rig. Best to build a OS20 with a specific OS20 race frame to keep that BB nice and low.

Find all of the compatible OS20 race parts over on this page, such as OS20 tyres and tubes. Plus our recommended forks.
