NEW for 2020! The ISM PN4.0 is the newest offering in the Performance Narrow category of saddles. Similar in design to the award-winning ISM PN3.0, we increased the sit bone contact points 5mm to accommodate a range of pelvic/body positions. Rider response told us some cyclists wanted a 125mm saddle to allow for more relaxed pelvis tilt related to road and gravel cycling.
