If you've ever experienced a saddle sore, you know all too well the grimaces that accompany them. A properly fitting saddle is your first defense against these ride-robbing lesions. The Prologo Scratch Pro Nack Saddle combines the race-ready silhouette of the Nago Evo with a profile of an endurance saddle for all-day comfort. It's especially well-designed for riders who spend the majority of the time in the saddle, even while climbing.

The Scratch Pro Nack has a variable stiffness frame made of injected carbon. Varying the stiffness allows the frame to flex in the middle, which leads to better shock absorption and less rider fatigue. The multi-density foam used on top of the frame follows the same principles. A softer padding lines the midsection while a firmer padding is placed across the paddle (the widest portion), where you sit. Firmer padding not only supports the sit bones, it also reduces 'bouncing,' which robs the power transfer to the pedals. The saddle is set upon Nack rails. These are carbon fiber woven with Kevlar, and they are interspersed with aluminum particles for reinforcement. They are strong and durable.

The round profile of the Scratch Pro Nack is one version of the three profiles Prologo offers. The rounded design provides even contact with the saddle across the sit bones, thereby minimizing hotspots. In conjunction with the round shape, the Easy Stroke Design, or ESD, transitions the widest part of the saddle into deep leg cutouts. This exaggerated silhouette reduces friction points along the inner thighs and helps transfer power more efficiently to the pedals. This endurance saddle was finished off with a tough microfiber cover that resists scratches and tears.

Prologo's Scratch Pro Nack Saddle is 134mm wide and comes in Full White, Hard Black, and Hard Black/white.
