The ISM PN3.1 Saddle

ISM proudly introduces the PN 3.1. Starting from the PN 3.0 chassis, ISM added more padding for riders who prefer a slightly softer ride. With a 120 mm rear end and 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 offerings 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.
