Utilizes our Performance Narrow 4 shape/chassis. The PN 4.0 is nearly identical in design to the award-winning PN3.0 model. The difference is we added 5mm of width to accommodate those with wider sit bones. Similar to our other PN saddles, the PN 4.0 offers superb thigh and hamstring clearance and utilizes the latest ATMOS molding manufacturing process to reduce weight. Like all ISM saddles, the PN 4.0 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.

Attention: 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.
