Description

The ISM 4.0 Saddle

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 5 mm to accommodate a range of pelvic/body positions.  Rider response told us some cyclists wanted a 125 mm saddle to allow for more relaxed pelvis tilt related to road and gravel cycling.

Like the other PN saddles, the PN4.0 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 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

  • 5 mm 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
  • Triathlon bikes
  • Time Trial bikes

How to Install an ISM Saddle

A well assembled ISM saddle fits better than any other saddle, so take the time to mount this saddle. On this page you will find several instructions and videos about mounting the saddle.

Have a saddle mounted?

Expert saddle fitting is available from us or from one of our dealers at an additional cost of €25. This includes fitting, advice and any subsequent adjustment.

Assembly videos and assembly instructions

An overview of assembly videos can be found here.

How long should my first ride be?

It is wise to let the first ride be shorter than usual. Build up this distance slowly. Because it is a different saddle than a conventional saddle, the body will have to get used to it first.

What should I do when ISM feels too wide?

If this is the case, it is recommended that you move the saddle slightly backwards. It could also be that the saddle is too high, in this case lower the saddle step by step.

What if my saddle can't go further back?

This is where people sometimes run into problems. What needs to be done. This requires a setback-style seatpost, some bikes have a double-sided option. The setback position is often used here with ISM saddles.

What should I do if I still have problems?

In this case, you can always call or contact us. For more information about this, please refer to this page.
