The articulated wishbone suspension with Horst Link has been used a lot, and brought to everyone's lips, by Specialized with its FSR. Later it was used by many brands, just to name a couple: Norco, Transition, Rocky Mountain, Mongoose.

Basically, the rear axle is located on the chainstays, near the wheel axle.

It is called Horst because it was invented and patented by Horst Leitner, an Austrian engineer who was personally involved in motocross competitions. This is one of the most adopted kinematics ever and in 1993 Specialized acquired the exclusive use of the system by acquiring the patent with all rights from Leitner. But then history saw many brands use practically the same system with slight modifications that circumvented the patent.

famac@famac.ind.br I am passionate about everything that has 2 wheels: in my youth I practiced competitive cycling on the road and on the track with good results. At the age of 18 I moved to cross country competing at national/international level as U23. Once I passed Elite, I made the choice to take things easier from the training point of view, and that's how my love for gravity disciplines was born, training as an FCI MTB instructor and guide. Now I have made my passion my profession by managing 3 MTB centers on the island of Elba (Elba MTB), creating the FANTAmtb and telling in an ironic but professional way, everything that revolves around MTB thanks to 365mountainbike and 365TV (YouTube 'PULITI dentro BIKER fuori').
