ISM PN 3.1 Bike Saddle

Inspired by the PN 3.0 model, the 3.1 Bike Saddle from ISM features enhanced padding and a tapered design offering you a comfortable seat for your ride.  

ISM Saddle that’s Perfect for Racing

The PN 3.1 features tapered edges and a 120mm rear end. This means it provides excellent clearance for the hamstring and thigh muscles, ensuring an unrestricted pedalling motion for putting as much power down as possible. It also facilitates freedom of movement as you change position on a climb or when diving into a bend.

Pressure Relieving Saddle Design

As with the entire ISM range, this saddle has the distinctive nose-less design to remove pressure from the perineum, encourage maximum blood flow and prevent numbness. This results in a much healthier, enjoyable riding experience.

  • Use: Triathlon, Time Trial, Road 
  • Rails: Chromoly (CrMo) 
  • Length: 255mm 
  • Width: 120mm 
  • Padding: 40-Series Foam 
  • Tapered-edge mould design for incredible comfort 
  • ISM Category: Performance Narrow
  • Size: 255mm
