ZoomISM
PN 4.1 Saddle
The ISM PN4.1 is the newest offering in the Performance Narrow category of bike saddles. Same shape as the popular PN4.0, only with increased padding for those looking to soften their ride. We engineered the PN4 chassis with sit bone contact points of 125mm to accommodate a range of pelvic/body positions related to road and gravel cycling.
Like the other PN bike seats, the PN4.1 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 PN4.1 is nose-less and designed to remove pressure from soft tissue, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.
Features:
- 125mm wide to accommodate a greater range of sit bone width
- Tapered-edge mold design for incredible comfort
- Auto-racing inspired air vent chassis
- Performance Narrow Shape
- 255mm Length, 125mm Width
- Chromoly Rails
