ISM PN 3.1 Black / Grey

Built on our Performance Narrow platform, the PN 3.1 saddle by ISM delivers the same trusted chassis as the PN 3.0, enhanced with additional padding for riders who prefer a softer, more forgiving ride. With a slightly wider 120mm rear section and a shorter overall length, the PN 3.1 provides increased support beneath the sit bones while maintaining a streamlined profile. The result is exceptional comfort that virtually “disappears” beneath you on long rides.

Like all PN models, the PN 3.1 is engineered to offer outstanding thigh and hamstring clearance. It features ISM’s advanced ATMOS molding process, which reduces weight while maintaining structural integrity. True to ISM’s signature design, this saddle is nose-less to relieve pressure from the soft tissue and perineum—promoting healthy blood flow, eliminating numbness, and ensuring a more comfortable, performance-focused ride.
