Transition with ease.

The restrictions set by governing bodies on saddle placement has led to a cohort of time trialists and triathletes spending countless miles perched precariously and uncomfortably on the narrow tip of traditional road saddles, trying to eek the most power out of a flat time trial course. This position is fast, but may be putting unhealthy pressure on sensitive nerves and tissues. ISM addresses this issue with the ISM PN 1.1 Saddle and its signature split fork, stocky-nosed design.

The PN 1.1 may look a bit alien next to a regular saddle, but it's built for comfort and function in a time trial position. Based on ISM's line-topping Attack saddle, the PN 1.1 features a blunted nose and cutout split to provide a more supportive platform than traditional pointy-nosed saddles, even when you're scooted up on the rivet to squeeze out those few extra watts. This saddle provides a bit more padding than the Attack to counter the minimal chamois found in most triathlon-specifc shorts, and the unique split design reduces pressure on soft tissue and nerves to increase overall comfort and reduce numbness.

The ISM PN 1.1 features an extra narrow, 110mm rear width to provide riders of all types with a variety of positioning options out on the road. This profile allows you to scoot back on the saddle to tackle a climb, perch on the nose to power through a flat section, and change positions as needed without any worries related to thigh and hamstring clearance. The result is less chafing, less numbness, and more fun on every ride.

A Comfortable Ride

  • Familiarity: I've used it several times

I have now ridden about 300 miles on this saddle and I find it to be very comfortable. I do not feel any pressure on my rear, even after more than 2.5 hours of riding. I did need a little time to get used to the thickness of the shortened nose but the cutout relieves pressure. I give it 4 stars now but would look to reevaluate the saddle after some 60+ mile rides.
