ISM PN4.0 saddle

The ISM PN4.0 saddle is the latest addition to the Performance Narrow saddle category. Similar in design to the award-winning ISM PN3.0 saddle, we have increased the seat bone contact points by 5mm to accommodate a range of body and pelvis positions. Feedback from riders told us that some wanted a 125mm saddle to allow for a more relaxed pelvic tilt associated with road and gravel cycling.

Like other PN saddles, the PN4.0 offers superb thigh and hamstring clearance. This allows the rider to move more around the saddle, which is ideal for diving into fast turns.

Like all ISM saddles, the PN4.0 is noseless and designed to eliminate pressure on soft tissues, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.
