Taking even ISM by surprise, the popularity of their PN 1.0 saddle has seen cyclists beyond the originally slated road bike design, including triathletes and time trialists, lap up its performance benefits. The distinguishing factor of the PN 1.0 is the narrow rear section. At 110mm wide, it is ISM’s narrowest seat, offering superb thigh and hamstring clearance. This enables for more rider body movement, and is loved by climbers that rest far back on their seats.
The front arms of the PN 1.0 feature a contoured downward slope. This can aid in allowing the rider to roll their hips forward for high power output, or for increased comfort with a high amount of saddle-to-handlebar drop.
Like all ISM saddles, the Attack is nose-less and designed to remove pressure from soft tissue, ensuring maximum blood flow, no genital numbness, and a healthier, more enjoyable ride. The PN 1.0 features a medium level of padding, similar to ISM’s Breakaway and Road models.
