That's for me as Pedelecfahrer extremely helpful, because you usually with increased speed drives over poor cycle paths and broken paving slabs and the rear wheel has no suspension. To save energy, but I'm driving on the rear wheel a relatively high air pressure, resulting in a hard tire and thus hard knocks.
The product absorbs this kicks off very well. Have come and yet had no reason for complaint so far about 1,000 km by product.
When buying a bike you should keep in mind that the saddle is positioned by the product approximately 3 cm further back and thus the minimum distance saddle, however - handlebar increased by 3 cm. In the border region rather then a smaller frame size should be chosen.
