This innovation, which has won the Eurobike Gold Award 2018, is at the same time a mechanically controlled dropper post for stepless seat height adjustment and high safety during stops, as well as a sensitive suspension seat post with 30 mm spring travel. Ambitious (E)-City and trekking bikers experience highest riding comfort with this first-class parallelogram seat post on gravel or cobblestone in an urban environment! This suspension comfort can be optimised exactly to the rider’s weight by means of the steel spring available in four spring hardnesses for riders weighing 45 to 130 kg. Using the ergonomic handlebar operating lever, the rider effortlessly lowers this dropper/suspension seat post by 80 mm before the descent, and benefits from optimum riding control and secure footing, e.g. when stopping at traffic lights, because of the lower centre of gravity. The external cable routing facilitates maintenance work.
