The ISM PN4.1 Gravel Road Saddle

The ISM PN4.1 is the newest offering in the Performance Narrow category of saddles.  Same shape as the popular PN4.0, only with increased padding for those looking to soften their ride.  We engineered the PN4 chassis with sit bone contact points of 125 mm to accommodate a range of pelvic/body positions related to road and gravel cycling.

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

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