ISM PN3.1 Performance Narrow Saddle

The ISM PN3.1 Performance Narrow Saddle is designed for riders who want a balance of race-ready efficiency and enhanced comfort. Built on ISM’s proven Performance Narrow platform, it suits aggressive road, triathlon and time trial positions where freedom of movement and pressure relief are critical.

Performance Narrow Shape: Using the Performance Narrow 3 chassis, the PN3.1 features a slightly wider 120 mm rear section and a shorter overall length. This design offers improved sit bone support while maintaining the narrow profile needed for efficient pedaling and dynamic body positioning.

Enhanced Comfort Padding: Compared to the PN3.0, the PN3.1 adds extra padding for riders who prefer a softer ride without sacrificing performance. The saddle is engineered to feel supportive yet unobtrusive, often described as “disappearing” beneath the rider during long or intense sessions.

Thigh and Hamstring Clearance: Like other PN-series saddles, the PN3.1 provides excellent thigh and hamstring clearance. This allows greater freedom of movement around the saddle, making it ideal for fast cornering, frequent position changes and high-cadence riding.

As with all ISM saddles, the PN3.1 uses a patented noseless design to eliminate soft tissue pressure. This promotes healthy blood flow, prevents numbness and supports a more comfortable, sustainable riding experience over long distances.
