Finally, A Saddle You Can Count On.

Have you been riding on the same old saddle for years now? Upgrade to an all-new saddle for the year of the ride, with comfort and durability that will last you for many adventures to come. The ISM Seat PN4.1 is the newest offering in the Performance Narrow category of saddles. This means that no matter if you prefer to ride gravel or road, you're in luck. Enhance your rides with the saddle designed to have you coming back for more.

With the same shape as the popular PN4.0, this seat features increased padding for those looking to soften their ride. The PN4 chassis has been engineered with sit bone contact points of 125mm to accommodate a range of pelvic and body positions needed to perform at road and gravel cycling. Like the other PN saddles, 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. Fitted with Chromoly rails for durability and 40-series foam padding for ultimate comfort, you're in for a treat.

If you've ridden with ISM saddles before, you know to expect the nose-less fit that makes for a more relaxed seat – no more uncomfortable numbness in your gentlest places. The ISM PN 4.1 Saddle is designed to remove pressure from soft tissue, ensuring maximum blood flow and a healthier, more enjoyable ride. With a tapered-edge mold construction and auto-racing-inspired air vent chassis, you'll want to hop on the bike time and time again.

  • Tapered-edge mold design for incredible comfort
  • Auto-racing inspired air vent chassis

Better than last versions

I had the 3.0 and it was too hard. This 4.1 version is very very nice. It does not rub my thighs and fits my bike without having to change my seat post. Also it is a little wider and i don't slide off the seat going up the hills.
