ISM PN 4.0 125mm Stainless Alloy Rails Saddle

Revolutionary in its approach, ISM designs products that relieve pressure on the perineum and soft tissue. Versatile and elegant, the saddle ISM PN 4.0 with stainless steel rails is equally suited to triathlon and time trials as it is to long road rides.

Designed in collaboration with athletes, the saddle features the Performance Narrow chassis. Comfort is further enhanced by the 125 mm rear seat area, which reduces chafing, and the redesigned edge profile. The seat also provides significant clearance for the thighs and hamstrings, allowing for a full range of motion.

Particularly well suited to aerodynamic positions and cornering at speed, the PN 4.0 causes no numbness thanks to constant blood flow. Whether setting a new record or enjoying long hours in the saddle, this model is the perfect candidate. In this version, it features robust stainless steel rails.
