Description
The ISM PS 1.1 Saddle is one of the most popular saddles for time trial riders and triathletes due to its supportive yet unrestrictive design. Designed specifically for riders who prefer an aggressive aero tuck position, the PS 1.1 offers ISM PS (Performance Short) profile with a 135mm width and 245mm length.
These measurements are complemented by a sloped rear section and the iconic forked frontal zone. The sloped rear section helps to provide maximum hip support without affecting your natural pedaling motion.
ISM's patented nose-less design is preferred by athletes who ride in an aggressive position with their weight shifted forwards because it removes pressure from soft tissue areas. This ensures maximum blood flow, alleviates genital numbness and promotes a healthier and more comfortable ride.
The medium to firm level of padding, rated a 30 on ISM's 65-point scale, maintains comfort during any ride from a short prologue to a full Ironman while the strong chromoly rails maintain stiffness without negatively affecting the saddle's weight.
