Our suspension seatpost absorbs vibrations, potholes and cobblestones for a smooth ride every day. Paired with a Brooks saddle, it’s the perfect combination for rough city roads and even country lanes.
Discreet and lightweight (420 grams), it maintains your bike’s sleek lines while offering comfort on a par with a touring bike. No flashy springs or complex mechanisms.
MDU technology is a high-performance foam composed of millions of tiny air bubbles. The foam absorbs energy rather than reflecting it back. Unlike a spring, which tends to bounce, MDU quickly stabilises the seat. The further you sink into the saddle, the greater the resistance becomes. This prevents the "bottom-out" effect (the sudden jolt at the end of the travel). This technology ensures comfort whilst remaining lightweight. MDU excels at filtering out road "noise" thanks to its microcellular structure, which acts as an acoustic filter. This suspension offers firmer, more stable support, which prevents energy loss whilst protecting your lower back.
Available in Silver and Black, it matches your Jitensha’s accessories. Compatible with all Jitensha.
