The radius profile has the roundest shape due to the rear section and maximum padding. The radius profile is designed for an upright posture. Normally, bicycles in this category have handlebars that are slightly higher than the saddle. The unique three-piece construction eliminates compression and tension normally found in conventional hard saddles with stretched uppers. This is achieved by applying a waterproof microfibre material directly to a flexible frame. This way, a softer foam can be used, which provides more comfort overall.
