NEW for 2020! The ISM PN4.0 is the newest offering in the Performance Narrow category of saddles. Similar in design to the award-winning ISM PN3.0, we increased the sit bone contact points 5mm to accommodate arange of pelvic/body positions. Rider response told us some cyclists wanted a125mm saddle to allow for more relaxed pelvis tilt related to road and gravelcycling.

Like the other PN saddles, the PN4.0 offers superb thigh and hamstring clearance. This allows for more rider body movement around the seat and is great for diving into fastcorners.

Like all ISM saddles, the PN4.0 is nose-less and designed to remove pressure from soft tissue, ensuring maximum blood flow, no genital numbness, and ahealthier, more enjoyableride.

This saddle is not recommended for cyclists who ride with ahigh seat position or those who ride very forward on the extreme front of the saddle (the front arms or the nose of atraditional saddle). The recommended seat height for these saddles calls for a32-37 degree knee bend for the rider. If you ride with aminimal bend or astraight leg adifferent ISM saddle is recommended foryou.
