Product Description

The 612 Ergowave Active has been specially developed to meet the needs of racers on road and mountain bikes. The saddle - with its wave-like shape and raised rear - provides a perfect rear hold and an optimal pressure distribution down to the deep structures of the body. Meaning, the power transmission to the pedal is considerably improved. The deeper nose combined with the deepening in the middle creates more room and free space for the dam area. The flat yet slim SQlab MaxContact saddle nose and the tight padding of the 612 were optimally adapted to the needs of the road bike. With SQlab Active saddle technology, the saddle follows the pedal movement, comfort increases, the intervertebral discs are mobilised and the pressure on the seat bones is minimised.

SQlab Ergowave
The new form of the SQlab step saddle for sporty sitting positions on mountain bikes and road bikes. Provides optimum pressure distribution around the sit bones - for even better performance and comfort. SQlab Active saddle technology comfort
The Active saddle allows a physiologically correct pelvis movement in horizontal plane, which relieves the intervertebral discs and minimises the pressure on the seat bones. The sporty active saddles are equipped with three different elastomer dampers, which are individually adjusted to the body weight and can be replaced as required. SQlab MaxContact
The flattened, narrow saddle nose offers a much larger contact surface and thus a greater pressure distribution than conventional saddles

Good saddle
Guter Sattel
Translated from German To the original

Not exactly cheap for me as a fitness driver. But the problems I had with the old saddle are gone. My tours range from one and a half to three hours. I would buy it again - I am very satisfied.

Nicht ganz günstig für mich als Fitness-Fahrer. Aber die Probleme die ich beim alten Sattel hatte sind weg. Meine Touren bewegen sich zwischen eineinhalb bis drei Stunden. Ich würde ihn wieder kaufen - bin sehr zufrieden.

Road bike saddle
Translated from German To the original

The saddle feels very hard and takes some getting used to, like any new saddle. When I got used to it, but once, I could see a huge improvement over the original saddle. How the product will prove itself over time will show itself over the years.

Der Sattel, fühlt sich sehr hart an und braucht eine gewisse Angewöhnungszeit, wie jeder neue Sattel. Als ich mich, aber einmal daran gewöhnt hatte, konnte ich, eine riesen Verbesserung, gegenüber des Original Sattels feststellen. Wie sich das Produkt, über die Zeit bewährt, wird sich über die Jahre zeigen.

Not suitable for MTB
Für MTB nicht tauglich
Translated from German To the original

2 saddles in use, neither of them survived long. With the first saddle, the two fastening struts bent after about 3-4 months. The replacement (guarantee) survived only a few months: there are 2 breakages under the saddle next to the two struts. I never had any more problems with the genital area, but just not really suitable for MTB. My weight: 80 kg

2 Sättel im Einsatz, beide haben es nicht lange überlebt. Beim 1. Sattel haben sich nach etwa 3-4 Monaten die beiden Befestigungsstreben verbogen. Der Ersatz (Garantie) überlebte es auch nur wenige Monate: es gibt unter dem Sattel neben den beiden Streben 2 Bruchstellen. Mit dem Intimbereich hatte ich nie mehr Probleme, aber eben, für MTB wirklich nicht geeignet. Mein Gewicht: 80 kg
