ISM PN 3.1 Road Bike Saddle

The ISM PN (performance narrow) 3.1. road saddle keeps you comfortable in the saddle during time trials, triathlons and long-distance road riding. Starting with ISM’s PN 3.0 chassis the PN 3.1 features more padding for a slightly softer ride; with a 120mm rear end and tapered edges the PN 3.1 is super-comfortable and offers superb thigh and hamstring clearance, allowing for more body movement around the seat. Like all ISM saddles the PN 3.1 is nose-less and has been designed specifically to remove pressure from soft tissue ensuring maximum blood flow with no numbness.

Mr KimThe width is reduced, which improves the power transfer. In addition, the material is improved in the previous model.
Mr NascimentoNice size and comfortable, big difference to simple narrow road bike. 165 lb Male, 5'7", tribike. Fast shipping!
SimonAlready using the 2.1 and needed another for my n+1 so went for this one as price was excellent from Merlin. It doesnt disappoint. All the ism comfort and this one is more compact in looks than the 2.1
