After years of anticipation, Supercross BMX has finally unveiled its OS20 version of the award-winning ENVY RS7 platform. The Majority of the popular ENVY RS7 features were carried over to this OS20 model with the addition of a direct disc brake mount and slightly redesigned geometry to account for the larger wheels.
The OS20 RS7 features:
- Tapered Headtube
- Fixed Disk Post Mount
- Threaded BB
- 15mm Dropouts
- Internal Brake Routing
- 160 mm rotor but you can still run a smaller 120mm rotor with a separate adaptor
The OS20 RS7 design is based around the regular 20" Supercross BMX Fork. Any Supercross 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 fork and want to go to OS20 all you need to do is swap the frame and wheels, and you're set to go!
