PN 1.1 Saddle
The ISM PN 1.1 features an extra narrow, 110mm rear width to provide riders of all types with a variety of positioning options out on the road. This profile allows you to scoot back on the saddle to tackle a climb, perch on the nose to power through a flat section, and change positions as needed without any worries related to thigh and hamstring clearance. The result is less chafing, less numbness, and more fun on every ride.

I was choosing between this and and the PN 3.0 model. Because I was unsure about the concept, I chose the less expensive option. Dunno if it was the right choice, but I love it and will likely buy another (perhaps the 3.0 model). It did take a little time to adjust but less than anticipated. First thing I noticed was that I spent much more time in the drops! Not a conscious thing, it just happened. Related to that, I started riding with my pelvis tilted forward which made the aero position more comfortable for my old arthritic spine as well as allowing my to push down more power. The contact points are different so it took a few longer rides to adapt, but the absence of numbness to an organ which should NOT be numb was very welcome on long rides!

This seat completely changed my riding experience. After 4 years of racing, countless saddle sores & bike discomfort I was genuinely ready to throw in the towel on ever finding a comfortable seat. I was tired of throwing money at the problem and had resolved to suck it up. This was a last ditch effort that actually worked. No numbness, significantly less chafing and no saddle sores after 300+ miles ridden. Cannot recomendable highly enough. Setup was easier than advertised and surprisingly plush/comfortable given its odd shape. Have found it superb for TT efforts and riding in the drops. Equal comfort climbing to boot. Safe to say a second ISM chair is on the way! Call me a convert.

Most comfortable saddle
- Familiarity:
- I've put it through the wringer
I have now made extensive use of this saddle. I've done several centuries and a few rides of 60+ miles. I can say this is by far the most comfortable saddle that I've ever used. I feel little or no pressure on any sensitive area. I recommend that everyone give this saddle a shot.

May be right for some, but not for me

Tried this after reading and watching videos about it, in my lengthy quest to find a reasonably comfortable saddle. This one does do what it's designed to do - instantly relieves pressure on soft tissues which aren't meant to bear weight. I expected a week or so of the kind of sit bone pain experienced during the first days of one's first road bike saddle, but that wasn't the problem. It significantly affected tendons connecting the innermost leg to the body, and the muscles supporting the soft tissues. I tried every saddle position and was still left with inflammation and bruising. It was the same for my husband. I suspect our problem was due to narrowly spaced sit bones. If yours are normal or wide, you should try this saddle. Keep in mind that body weight or aesthetic perceptions of body shape don't determine sit bone spacing. There are skinny, hipless pros with normal sit bone spacing. Also keep in mind that your seatpost setback is relevant to fore/aft positioning; the recommended 3" back was too far for my 35mm setback. And definitely lower the saddle per recommendation. If you get the positioning right and it fits your bone width, it could solve any saddle comfort issues.

After about 200 miles sits bone discomfort became prohibitively painful. Initially it felt amazing. Medial thigh friction was observed but was not prohibitive personally. Numbness felt from other saddles abated. The search continues.

A Comfortable Ride
- Familiarity:
- I've used it several times
I have now ridden about 300 miles on this saddle and I find it to be very comfortable. I do not feel any pressure on my rear, even after more than 2.5 hours of riding. I did need a little time to get used to the thickness of the shortened nose but the cutout relieves pressure. I give it 4 stars now but would look to reevaluate the saddle after some 60+ mile rides.

I"m like you, I was puzzled between this and the PN 3.0. Definitely better than the prior saddle. And yea, aero is more tolerable. This isn't the first prong saddle I've used, but it's the first ISM.
