ISM proudly introduces the PN 3.1. Starting from our PN 3.0 chassis, we added more padding for riders who prefer a slightly softer ride. With a 120mm rear end and and tapered edges, the PN 3.1 is so comfortable, it will “disappear” underneath you.Similar
ISM’s Performance Narrow saddles feature a 110mm width to allow for more rider body movement around the saddle. The PN 1.0 has a firmer padding, for competitive cyclists and road racers. 25-series foam-and-gel padding
