Saddle: ISM Attack
Progression: Anatomical tongs for the aero position, slender rear section for upright riding

ISM’s anatomical design has revolutionized triathlon saddles. They have been the solution to undercarriage discomfort for many triathletes, but they do have a drawback. The ultra-wide design can chaff some riders’ thighs, especially when pedaling out of the aerobars. The Attack was created to rectify that problem. The tongs are still very broad and ISM says they will stay that way. Narrow design will impair blood flow they say, but the rear section of the Attack is much narrower than their other models. This change may reduce or eliminate the most common criticism of these exceptionally comfortable triathlon saddles.
