ISM PN1.1 Triathlon Saddle

Of course not everyone can enjoy the same bike saddle, this is because everyone is differtent from each other. Some people wanted more comfort but a lower price.

The ISM PN1.1 is the first bike saddle of the new generation ISM seats. The ISM PN1.1 has the stuffing of the 40-series (the number is a new way to show the softness of the ISM seats). This is the same stuffing as in the Prologue. It is ideal because at triathlons you usually use a thin shammy. The point of the ISM PN1.1 is that it points a bit down at the back so the rider are a little bit more unlimited with tilting the hip. The famous ISM slot did already help that process. This puts no pressure on the noble parts, which gives you no problems with bad bloodflow or insensibillity.

The ISM PN1.1 is suitable for time trial bikes and road bikes. Makes your ride enjoyable and comfortable again.

Every ISM Seat is different from all the other bike seats from other brands. It is different in many aspects like:

  • ISM seats are bike seats where you really sit on. The ISM racebikesaddles are flat, most of the other saddles are convex. Because this seat is flatter the place where your sacrum is on the seat is really comfortable.
  • The upperside of the bike saddle is cm lower than then other bike saddles.
  • The racing bike saddles has some extra because this seat is in fact noseless, but the saddle has to follow the rules of the UCI and the US.
