    • ISM PN4.0 Bike Saddle

  • ISM PN4.0 Bike Saddle

    Designed for high-quality performance, this Bike Saddle from ISM is 5mm wider than ISM's 3.0 model, so it can fit a wider range of sit bone sizes. This saddle also features 30-series foam padding and stainless-steel rails for a comfortable, secure ride.  

    The ISM PN4.0 is in the Performance Narrow category of saddles. Similar in design to the award-winning ISM PN3.0, ISM increased the sit bone contact points 5mm to accommodate a range of pelvic/body positions. Rider response told ISM that some cyclists wanted a 125mm saddle to allow for more relaxed pelvis tilt related to road and gravel cycling.

    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 fast corners.

    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 a healthier, more enjoyable ride.
