Introducing the Jon Fromm Signature Prime Frame from 50/50. Jon was heavily involved with the development of the Prime frame so it was only fitting to thank him with the first model.
Jon’s Prime walls are bright white with a printed logo in metallic gold. We used electroplating to create the brilliant gold axles, and anodizing on the Core to complete the look.
The frames utilize the Core System 2. Optimized for antirocker but incredible for flat
