Pn 3.0

The ISM Pn 3.0 is a noseless saddle engineered specifically for riders who spend long hours in an aggressive or aero position. Its split-nose design removes pressure from soft tissue, making it a popular choice for triathletes, Time trialists, and endurance road cyclists grinding through multi-hour efforts on routes like the Pune–Mahabaleshwar climb or Chennai's flat coastal stretches.

Use Cases

Daily training. Reliable use across Indian training conditions — heat, humidity, and rough tarmac.

Race day. Performance-grade construction for competitive efforts.

Long rides. Built for full-day rides across Western Ghats, Sahyadri, or Nilgiri climbs.

Our Take

ISM's Pn 3.0 addresses a problem that heat makes worse: perineal pressure builds faster when core temperature rises above 35°C. The split-nose format distributes load to sit bones rather than soft tissue, which is genuinely useful on India's longer climbs and brevet routes through Coorg or Ooty. Give it at least six rides before forming an opinion — position on the rails matters more than on a conventional saddle.

Sizing for Indian Riders

ISM saddles fit differently from conventional designs — you typically sit further forward, so measure sit-bone width (cardboard method, add ~25mm) and consult ISM's fit guide before ordering. Indian riders with sit-bone widths in the typical 130–155mm range generally find ISM's standard width appropriate. In sustained heat, chamois cream is strongly advised regardless of saddle choice.

Compatibility Notes

The Pn 3.0 uses standard 7×7mm rail clamps and fits seatposts sized 27.2mm, 30.9mm, or 31.6mm. If your seatpost uses carbon-rail clamps, confirm torque specifications with the manufacturer. ISM recommends a more forward saddle position than conventional saddles — factor this into your bike fit before locking in cleat and bar adjustments.

Pairs Well With

The Pn 3.0 works best alongside padded bib shorts or bib tights for long-distance sessions, a layback or aero seatpost suited to your frame, chamois cream for hot Indian riding conditions, and a compact saddle bag that clears the split-nose profile without rubbing.
