Pn 3.1

A poorly chosen saddle can end a ride before it should. The ISM Pn 3.1 is built around ISM's signature dual-nose design, which redistributes pressure away from soft tissue — a genuine advantage for Indian riders logging long hours on climbs from Lonavala to Ooty or grinding through Pune's weekend training routes in peak summer heat. Cobbled Climbs is the authorised retailer for Time in India.

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

The ISM Pn 3.1 suits riders who spend serious time in an aggressive, forward-leaning position. In India's 35°C+ riding conditions, pressure relief matters as much as padding density — and ISM's cut-out channel design addresses both. Whether you're chasing a brevet finish or building base miles on Delhi's early-morning roads, this saddle rewards commitment. Allow five to six rides before forming a firm opinion.

Sizing for Indian Riders

ISM saddles run on the narrower side compared to conventional designs, reflecting their forward-weight-bias geometry. Indian riders should measure sit-bone width — sit on firm cardboard, mark the dimples, measure between centres, then add approximately 25mm. Most riders fit comfortably within ISM's standard width offering. In humid conditions like Chennai or Kolkata, a snug but pressure-free fit prevents chafing better than oversizing.

Compatibility Notes

The ISM Pn 3.1 uses standard round rails compatible with most 7×7mm seatpost clamps. Match your seatpost diameter to your frame — common sizes include 27.2mm, 30.9mm, and 31.6mm. If fitting to a carbon seatpost, use manufacturer-recommended torque settings to avoid rail damage. Minor fore-aft and tilt adjustments significantly affect comfort; take time to dial in position across several rides.

Pairs Well With

Pair the ISM Pn 3.1 with high-quality padded bib shorts for long-distance comfort, a layback or setback seatpost to fine-tune your position, chamois cream for hot multi-hour rides in Indian summer conditions, and a compact saddle bag for essentials on Coorg or Western Ghats rides.
