Our V2 perches are made from ulta strong cold forged aluminium with a nylon sleeve which allows the perch to rotate under impact.  This combination makes them so good that we offer 3 full year warranty for the perch without no questions asked. "If you break it we will replace it". Some other nice features are on-the-fly adjuster, a heavy-duty lever cover and a 9mm lever thickness in the clamp area make it the best selling perch in Germany!
