Supercross OS20 SX450 Frame chromoly

The OS20 SX450 features:

- Campy Integrated Headtube

- Side Mount Disk Brake Mount

- Threaded BB

- 3/8" Dropouts

- External Brake Routing

Available in 3 different sizes to fit all riders and 3 stock colors (Jet Black, Show Chrome and RAW ) and more to come.

If one of the stock colors isn't what you want, we still do custom Powdercoat and Ceracoat to make the SX450 truly yours! Give us a call, and we will get you hooked up. 

When we designed the geometry of the OS20 SX450 we based it on the regular 20" Supercross BMX Fork. Our 20" Carbon Race forks will work with the OS20 wheel, so no need to buy a OS20-specific fork. If you already have a 20" Supercross and want to go to OS20 all you need to do is swap the frame and wheels, and you are set to go!
