All ISM saddles are nose-less for the purpose of removing pressure from soft tissue areas and ensure maximum blood flow for a healthier and more comfortable ride. The ISM PN 1.1 Saddle has a narrow performance shape, but geared towards those who prefer a bit more padding in a race sized seat. The narrow shape allows for maximum thigh and hamstring clearance. The front end of the ISM 1.1 has a downward slope. This is incredibly useful for a triathlete or time trial rider with an aggressive saddle to handlebar drop height. The riders hips are free to roll forward into a higher power output position.
The front arms of the PN 1.1 feature a contoured downward slope
Built on the shape and platform of ISM's successful Attack saddle, but with slightly more padding
Useful for triathletes using thin shorts, or anyone who simply prefers additional padding in the Performance Narrow shape
I purchased this bike as part of a new bike build. The seat is most comfortable in the aero position which is good for a triathlon bike. This is my first open nose saddle and that has taken some getting used to but has been more comfortable the more time I spend in the saddle.
