ISM Performance 4.0

The ISM PN4.0 is the latest offering in the Performance Narrow saddle category. Similar in design to the award-winning ISM PN3.0, ISM has increased the sit bone contact points by 5 mm to accommodate a range of pelvic and body positions. From rider feedback, they learned that some cyclists desired a 125 mm saddle to allow for a more relaxed pelvic tilt while riding on the road and gravel. Like the other PN saddles, the PN4.0 provides excellent thigh and hamstring clearance. This allows for more body movement around the saddle, making it great for diving into fast corners. Like all ISM saddles, the PN4.0 is nose-less and designed to relieve pressure from soft tissue, ensuring maximum blood flow, no numbness in the genital area, and a healthier, more comfortable ride.
