Sillín ISM PN 3.0

The ISM PN 3.0 Saddle is built for triathletes and time trial riders who want firm support and maximum efficiency in an aerodynamic position. Part of ISM’s Performance Narrow series, the PN 3.0 uses a 120 mm narrow profile and ISM’s signature split-nose design to reduce soft tissue pressure and improve blood flow during long efforts.

Compared to the softer PN 3.1, the PN 3.0 uses 30-series padding for a firmer, more responsive feel. This makes it a favorite among athletes who prefer solid support when putting down consistent power over long training rides and races.
