NEW for 2021!  The ISM PN4.1 is the newest offering in thePerformance Narrow category of saddles. Same shape as the popular PN4.0, only with increased padding for thoselooking to soften their ride.  Weengineered the PN4 chassis with sit bone contact points of 125mm to accommodatea range of pelvic/body positions related to road and gravel cycling.


Like the other PN saddles, the PN4.1 offerssuperb thigh and hamstring clearance. This allows for more rider body movement around the seat and is greatfor diving into fast corners.


Like all ISM saddles, the PN4.1 isnose-less and designed to remove pressure from soft tissue, ensuring maximumblood flow, no genital numbness, and a healthier, more enjoyable ride.
