ISM PN 3.1 Saddle

About ISM PN 3.1 Saddle
ISM Saddles have been the most used saddle in Ironman since 2013, and the popularity is due to the best comfort when on long rides and races while still maintaning the most areodynamic & efficient position.

Utilising ISM's Performance Narrow 3 shape/chassis. The PN3.1 uses the same chassis as the PN3.0, but with added padding for those seeking a softer ride. With a slightly wider 120mm rear and shorter length, the PN 3.1 offers more support under the sit bones and is so comfortable, it will “disappear” underneath you. 

Similar to ISM's other PN saddles, the PN 3.1 offers superb thigh and hamstring clearance and utilises the latest ATMOS molding manufacturing process to reduce weight. Like all ISM saddles, the PN 3.0 is nose-less and designed to remove pressure from the soft tissue/perineum, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.

About ISM
ISM was founded by avid cyclist and swimmer Steve Toll in Tampa, Florida, after setting out to solve the discomfort many riders experience with traditional bike saddles. In 1997, Steve developed the original concept for a more comfortable saddle design, which was patented in 1999.

Since then, ISM has become renowned for producing some of the world’s most comfortable bike saddles, trusted by both professional athletes and everyday riders alike. Their innovative designs have supported Ironman victories, Olympic medals and podium finishes across the globe, helping cyclists ride further and perform at their best in greater comfort.
