PN 1.0 – $249.88
Utilizes our Performance Narrow 1 shape/chassis. The PN 1.0 is ready to take on any road and was our first foray into narrower designs. While originally slated as a competitive road bike saddle, it has proven to be equally loved by triathletes and time trialists. The PN 1.0 is 110mm wide, offering superb thigh and hamstring clearance for riders who prefer a slack road position or aerobar athletes looking for hamstring clearance as their hips rotate forward. Like all ISM saddles, the PN 1.0 is nose-less and our patented design eliminates pressure from the soft tissue/perineum, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride.

Customer Reviews of The PN 1.0 Saddle
I’ve ridden the PN 1.0 for almost 6 years now on my TT rig. Depending on the course, my empirical data from longer rides and bike fits show this saddle is worth 5-10 watts compared to more conventional saddles for a given heart rate. Every year I try other saddles and I’ve not found a more ergonomic or comfortable option for riding in the bars. The design allows lots of flexibility for dialing in an excellent aero position. The durability is noteworthy. I logged over 6,000 miles on the PN 1.0 and only show some light scuffing at the inner thigh contact points with zero detectable break down of the padding.
I do a lot of time trials including 10, 25, 50, 100, 12 Hour and this year in July I also had a 24 Hour TT planned. Because of the discomfort last year I was using a sanitary towel to try and remove some of the pressure. I then lent an ISM Racing saddle from my local bike shop and this certainly relieved the pressure but I found it a little wide. I reviewed the saddles on the ISM website and ascertained that the PN1.0 looked slimmer. I contacted ISM and applied for their demo program and they sent me a PN1.0 saddle to try. I used it the week before my 24 Hour TT on a 45 mile ride and it seemed ok. The proof would be the following week on my 24 Hour Time Trial which I achieved 374.025 miles and the saddle did its job. I can therefore recommend this saddle 100%. I am now looking forward to receiving my new saddle.
