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.
