Designed for sporty (e)-city / trekking drivers, this steplessly lowerable parallelogram suspension seatpost significantly increases riding comfort. The D.2 ST-Ri, which won the Eurobike Award 2018, features a approved parallelogram suspension design and a finely tuned steel spring. This results in 30 mm spring travel that reliably absorbs road shocks. This means top seating comfort – no matter if 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: It can be lowered with a push on the ergonomic operating lever, which is installed on the handlebar. In order to avoid fatigue, frequent riders can adjust the seat height continuously. The steel 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 maximizes riding pleasure with 80mm dropper travel.
