Technology:

Trifecta Suspension
The background to the eye-catching Trifecta Suspension design is the use of a high pivot, i.e. a main pivot point that is not located near the bottom bracket but higher up on the seat tube. This has the advantage that the rear wheel does not move forwards when you compress the suspension, but backwards and thus does not brake your movement, but goes along with it. This also makes the rear triangle a little longer, which increases stability under heavy compression. It allows you to ride faster and more controlled on rough terrain. The finely tuned anti-rise forms a counterpart to the sagging of the fork under heavy braking and ensures consistent chassis stability. The idler pulley with chain guide counteracts pedal kickback and is optimally positioned for efficient pedalling with ideal anti-squat. As far as the transmission ratio is concerned, the Rate Control Linkage bell crank enables separate tuning of the different spring travel ranges by means of relatively small links, i.e. without relying exclusively on strong progression. This way you get adequate support in the middle travel and still don't have to fear hard hits.

One-Ride Geometry
With the aim of offering the same riding experience to everyone regardless of body size or figure, FORBIDDEN have developed the One-Ride geometry. This system is characterised by the fact that the weight distribution is adapted to each frame size, which manifests itself in different chainstay lengths for each size, for example. The real seat angles become steeper with frame sizes, which improves the riding position on larger frames, when compared to comparable frames. The head tube length also increases more than usual with each size in order to better cover more unusual body sizes.
