Description

ISM PN 4.0 SaddleThe ISM PN 4. 0 is the newest offering in the Performance Narrow category of saddles. Similar in design to the award winning ISM PN 3. 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 PN 4. 0 offerings superb thigh and hamstring clearance.

The ISM PN 4.0 is the newest offering in the Performance Narrow category of saddles.  Similar in design to the award-winning ISM PN 3.0, 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 PN 4.0 offerings 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 PN 4.0 is nose-less and designed to remove pressure from soft tissue, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.

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.

Key Features

  • 5mm wider than the PN 3.0 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

Ok substitution for the value
Size: Single Slat, Color: Chrome
Bought these for my 2004 M3, quality is good, fitment is OK, some gaps around the edges but you cant tell unless you look very closely. About as expected for the cost.

Last about a year ishhh
Size: Single Slat, Color: Glossy Black&M-Color
Plastic mold isn’t as straight as it should be, the clips don’t line up like oem. Product is wiggly. Had on car for over half a year. Hasn’t faded. Just wish the fitment was better. Update: the grill lasted about 1 1/2 years, it began to fade, and I had a slat crack, no evidence of impact. I ended up buying a better made product and replaced this grill.
