ISM Saddles is an American saddle brand founded in Tampa, Florida, built around a single core idea: eliminating the discomfort and health issues caused by traditional bike saddle design. Patented since 1999, ISM's unique nose-free design supports the rider's pubic rami bones rather than compressing soft tissue, nerves, and arteries — enabling full blood flow and pain-free riding regardless of how aggressively the rider rotates their hips forward.

Their range spans two categories: performance saddles (available in narrow, long, short, recreation, and mountain variants for road, triathlon, and MTB athletes) and comfort saddles (city and fitness models for casual and commuter riders). ISM is equally at home on a police patrol bike as it is at an Ironman finish line, with a strong following among triathletes, age groupers, and professional athletes including Ironman and Olympic-level competitors.

Because of the nose-free geometry, ISM saddles require a specific setup — positioned further rearward and approximately 5mm lower than a traditional saddle — making proper installation essential for optimal comfort and performance.
