The wait is over - Forbidden’s full-blown downhill machine has officially arrived. After years of development and countless prototype runs on the World Cup stage, the Supernought is here with one goal: pure, uncompromised speed.
Built around Forbidden’s class-leading high pivot design and delivering a massive 205mm of rear travel, this bike is engineered to stay composed through the nastiest terrain you can throw at it. Roots, rocks, square-edge hits - it handles it all with control and confidence.
The Supernought isn’t just fast, it changes the way you ride. You'll find yourself pushing harder, cornering faster, and hitting lines you used to avoid. It’s that good. And it’s built with one thing in mind: getting you down the hill faster, smoother, and with a bigger grin on your face.
Intended Use: DH Race
Suspension: 205mm Rear / 200mm Front
Wheel Size: 29" or Mixed (MX)
