ISM is excited to present the PN 3.1 saddle. Building on the PN 3.0 chassis, we've added extra padding for riders who like a slightly softer feel. With a 120mm rear end and tapered edges, the PN 3.1 is so comfy that you'll hardly notice it under you. Similar to other PN saddles, it offers excellent thigh and hamstring clearance, allowing for more body movement around the seat. This is great for taking fast corners. Like all ISM saddles, the PN 3.1 is nose - less, designed to relieve pressure on soft tissue, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.

This saddle isn't suitable for cyclists with a high seat position or those who ride far forward on the saddle. The recommended seat height requires a 32 - 37 degree knee bend. If you ride with a minimal bend or straight leg, choose a different ISM saddle.


Using the ISM PN 3.1 saddle is straightforward. Just mount it on your bike following the standard procedure. When riding, make sure your seat height allows for a 32 - 37 degree knee bend for the best comfort and performance. Don't use this saddle if you have a high seat position or tend to ride very far forward on the saddle.
For maintenance, keep the saddle clean. You can use a mild soap and water to wipe it down regularly. Avoid using harsh chemicals as they might damage the padding or the finish. Check the rails and the mounting points periodically for any signs of wear or looseness. If you notice any issues, tighten the bolts or replace the parts as needed. With proper care, your ISM PN 3.1 saddle will serve you well for a long time.
