The P3 model from Portuguese component manufacturer Gelu is by far the lightest option available in a triathlon / time trial specific saddle, featuring full carbon construction with 7x9 oval saddle rails and a 3K weave, high gloss finish. Yet far from being merely lightweight, the P3's design is intended to provide as much comfort as possible when riding in an aggressive, aerodynamic position. The saddle shell is engineered to flex slightly under load and is equipped with a long, wide relief channel with corresponding wide nose. This shape allows the rider to easily modify their position by sliding forward and backward when riding - an important feature for long, hard efforts. The P3 may also be a good option for riders needing a slightly wider base for comfort.
