>>1392373I have 2 ISM saddles on my bikes (PR and PN)
Bought them mainly because I ride a very aggressiv and aero position on both of my road bikes and on my old selle italia saddles I was feeling a lot of pressure and some pain when riding in said position. Didn't really get all too much dick numbness but I had problems relaxing into a deep aero position and couldn't hold it well either.
With the ISM saddles I have no problem whatsoever. No numbness no pressure nothing. They are very popular with triathletes and TT racers for that reason. You can rotate your hips forward without feeling uncomfortable and once you get used to being able to do that it's hard to go back to a normal saddle. Everytime I ride a bike with one it feels fucking weird because I don't know how to sit on it properly anymore kek.
It takes some time to set them up though. Since you sit way different on the ISM saddles you have to adjust your saddle height, ISM has a short guide on that. You can't sit on them like you'd sit on a normal saddle either, if you try it'll be very uncomfortable and weird. They also have some illustrations on how you're supposed to sit on their saddles as a guideline.
That being said they are expensive as fuck. From my experience it doesn't really matter which model you get. I bought both of mine used for cheap which is why I have two different models, they both work the same. The PN series 'looks' the best and I'd take on of them again because they are more narrow which I found is better.
