You're here because you've been getting some form of saddle discomfort - numbness, chaffing, soreness. And you've had a friend tell you to take a look at ISM saddles. But you aren't ready to commit to a single saddle, and the number of ISM models is daunting. - No worries! The PS series is right smack in the middle in terms of widths, and works for most riders, triathletes and road cyclists alike. The PS 2.0 is the saddle we would recommend to anyone who is unsure of where to begin. Demo the PS 2.0, and you’ll get a better idea if you would like a narrower (PN), longer (PL), or wider (PR) chassis.
