The ACTIVE models are a good fit for trekking and touring bikes and also work well on cross bikes or ATBs because they are designed for a stretched position, in which the load on the saddle is shifted from the sit bones towards the centre of the saddle. The ergotec Flex T-Zone adapts the saddle surface individually to the anatomy of the human seat, while the closed ergotec Comfort Cutout Plus features under the sit bones absorb shocks like a trampoline. The ergotec relief ridge and the ergotec Comfort Cutout relieve the perineum and pubic bone. The ACTIVE saddles are available in medium and strong and come in two widths (S and M). All ES ACTIVE saddles are suitable for both conventional and e-bikes.
