The ISM PN 1.1 saddle provides all the race-proven benefits of the famed Attack saddle but adds a little more cushion to the highly-vaunted narrow performance shape. The incorporation of 40-series padding means a more plush gel foam layer underneath the synthetic leather cover for cyclists looking for a softer ride. The front arms are curved slightly downward to encourage the hips to roll forward for more power output and for more comfort on bikes with high saddle to bar drop. ISM’s signature nose-less design has been scientifically proven to reduce pressure encourage blood flow and prevent numbness.
