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 a range of pelvic/body positions. Rider response told us 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.
Key Features:
- 5mm wider than the PN3.0 to accommodate a greater range of sit bone width
- Tapered-edge mold design for incredible comfort
- Auto-racing inspired air vent chassis
Commonly Used For:
- Gravel/Road bikes
- Time Trial bikes
Tech Specs:
- Category: Performance Narrow
- Length: 255mm
- Width: 125mm
- Padding: 30-Series Foam
- Rails: Proprietary Stainless Steel Alloy
This saddle is not recommended for cyclists who ride with a high seat position or those who ride very forward on the extreme front of the saddle (the front arms or the nose of a traditional saddle). The recommended seat height for these saddles calls for a 32-37 degree knee bend for the rider. If you ride with a minimal bend or a straight leg a different ISM saddle is recommended for you.
