The Kinekt Suspension Seat Post by Cirrus Cycles is a high quality seat suspension system based on a parallelogram design which moves with the whole body as the rider pedals over all types of terrain, providing a better connection from the rider to the surface and with the bike as a whole. These posts can be installed on all seats and styles of bikes. Each one is made to the size of the bike’s seat post diameter which you send to Cirrus when placing your order for a proper fit. With a low setting of one going up to eight for a tighter response to going over bumps and obstacles, it is fully adjustable to each rider;’s preferences. This seat post is adaptable to E-Bikes, Road Bikes, Hybrid & Mountain, Folding and Cruisers too!
