ISM PS1.0 Performance Short Saddle

The ISM PS1.0 is built for riders who prefer a stable, locked-in position on the bike. Its Performance Short chassis is optimized for aggressive road, time trial and triathlon positions where consistent posture matters more than frequent movement on the saddle.

Aero-Optimized Shape: Featuring sloped front arms and a slightly raised rear section, the PS1.0 provides excellent hip support when the rider’s body is rotated forward. This shape is especially effective for aerobar use and flat, fast courses where holding one position delivers maximum efficiency.

Balanced Padding for Performance: The saddle uses ISM’s proven 15-series padding, offering a firm yet supportive feel. This balance helps maintain comfort during sustained efforts without sacrificing power transfer or responsiveness, making it well-suited for race-focused riding.

Nose-Less Pressure Relief Technology: Like all ISM saddles, the PS1.0 uses a patented nose-less design to eliminate pressure on soft tissue. This promotes healthy blood flow, prevents numbness and supports longer, more comfortable rides in aggressive positions.

The ISM PS1.0 is ideal for athletes who settle in and stay focused. Its stable platform, pressure-free design and race-inspired graphics make it a dependable choice for time trials, triathlons and fast road efforts.
