ISM proudly introduces the PN 3.1. Starting from our PN 3.0 chassis, we added more padding for riders who prefer a slightly softer ride. With a 120mm rear end and tapered edges, the PN 3.1 is so comfortable, it will “disappear” underneath you. Similar to the other PN saddles, the PN 3.1 offering 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 PN 3.1 is nose-less and designed to remove pressure from soft tissue, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride. This saddle is not recommended for cyclists who ride with a high seat position or those who ride very forward on the extreme front of the saddle (the front arms or the nose of a traditional saddle). The recommended seat height for these saddles calls for a 32-37 degree knee bend for the rider. If you ride with a minimal bend or a straight leg a different ISM saddle is recommended for you.
