Often times, first editions aren't the best. Books are the exception. The Prologo Nago Evo TR is based on the popular Prologo Nago saddle, but is the evolution of that shape into something greater. The TR version simply takes it a step further.
The Nago Evo saddle's overall dimensions are 280x134mm. With a mostly flat saddle shape, the Nago Evo will force most people up on their sit bones and take pressure off the Perineal area. Further reducing pressure is the Prologo Active Density padding. The saddle base—in the TR's case a 27% carbon fiber injected polyamide nylon structure—is designed to flex at different sections more than others. The padding is a ultra soft on the nose for comfort when Time Trialing, more firm in the Perineal area with a thinner base for flex to decrease pressure, and a firm density at the sit bones for correct pelvic support. The TR version of the saddle features the aforementioned increased amount of carbon content over the base model's 18%, heat-treated solid Titanium rails for increased stiffness, and a more supple microfiber cover versus the base model's microfiber. These differences, though seemingly minor, add up to create a saddle that transfers more power to the pedals and is more comfortable on long rides than it's competitors. Look closely at the Contador's bike and you'll see the Prologo Nago Evo TR perched atop his seatpost.
