Noseless Triathlon Bike Saddle - 250x130mm Supportive Aerodynamic Design

Product Description
The ISM PS 1.0 is a high-performance noseless cycling saddle designed especially for triathlon, time trial, and aggressive aero riding positions. Built around ISM’s Performance Short chassis, the PS 1.0 is one of the brand’s most popular performance saddles for riders who spend extended time rotated forward in an aerodynamic position.

Its distinctive split-nose design is engineered to reduce pressure on sensitive soft tissue compared with traditional saddle shapes. The slightly raised rear section provides strong hip support when the pelvis rotates forward, while the sloped front arms help reduce unwanted contact and chafing.

The PS 1.0 uses ISM’s firmest 15-Series foam and gel padding, making it a performance-focused choice for riders who prefer a supportive, stable platform rather than a heavily cushioned saddle.

This saddle is a take-off item and may show light handling marks, small scuffs, or minor signs of installation/removal. Any wear present is expected to be cosmetic only unless otherwise noted.
