NEW for 2021!  The ISM PN4.1 is the newest offering in the Performance Narrow category of 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 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.

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.

Key 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

Commonly Used For: 

  • Gravel bikes
  • Road Bikes

Tech Specs:

  • Category: Performance Narrow
  • Length: 255mm
  • Width: 125mm
  • Padding: 40-Series Foam
  • Rails: Chromoly

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.

Holds up well!
Size: 4 Pack, Size: 4 Pack
We used these brackets to hold up our snowboards on the wall (as seen in photos, apologies for the bad quality) and they held up very well. The brackets were a little hard to get into the wall, but that may have been the area we put them in. But for the most part the installation was simple, they looked nice, served its function, and are worth the money

Just what I needed.
Size: 6 Pack
A little on the pricey side, but really sturdy and well made. I needed an odd size set of brackets to fit a shelf in an awkward spot. I wasn't sure I'd find brackets with arms long enough for my needs without using some ugly white hardware-store shelf brackets. These look great, are very heavy duty, and just what I needed. I debated the purchase because of their initial cost, but once I got them I realized their quality warranted the premium price. Overall I'm very happy with them.
