Designed for sporty (E)-City/trekking drivers, this continuously lowerable parallelogram suspension seatpost significantly increases riding comfort. The D.2 ST-Ri, which won the Eurobike Award 2018, features a proven parallelogram suspension design and a finely tuned steel spring. The resulting 30 mm spring travel reliably absorbs road shocks. This means top seating comfort – regardless of whether you are riding on bumpy dirt roads or in urban areas. The D.2 ST-Ri’s dropper function increases riding control and safety when stopping at traffic lights or riding downhill: the spring support is lowered by means of an ergonomic handlebar operating lever. In order to avoid fatigue, frequent riders can adjust the seat height continuously. The Bowden cable of the mechanically controlled D.2 ST-Ri runs protected within the frame. The D.2 ST-Ri is the perfect combination of suspension and dropper seatpost and maximises riding pleasure with 80mm lowering.
