The Prologo Dimension R2 Nack Saddle featured here at Escapa is Prologo’s high-performance ergonomic saddle, positioned at the top of the Dimension family lineup—one of the most popular on the market in recent years. A versatile, compact saddle perfect for road, dirt, and XC/Marathon mountain biking, designed for professionals and the most demanding amateurs who are always seeking maximum performance and high-end components.
Anatomical Shape
The Dimension R2’s V-shape ensures minimal movement and more precise positioning on the saddle’s surface. Its advanced anatomical center facilitates a more forward-leaning position. Its flat anatomical shape, which promotes an even more forward-leaning and aerodynamic riding position, makes it ideal for riders with excellent pelvic flexibility.
Technologies
The Dimension R2 features a completely redesigned nose, 40 mm wide (6% wider than the previous model), and a more rounded side profile. The new design is intended to further increase the saddle’s comfort, especially during peak pedaling pressure. The PAS (Perineal Area System) channel, open in the center of the saddle, is designed to eliminate pressure peaks and numbness. The new EVA foam has allowed us to reduce the thickness of the rear padding by 1 mm—20% less than the previous model. This reduction in padding has helped lower the overall weight while maintaining the saddle’s support and comfort.
Base and Rail
The rail can be made of Nack (nano carbon fiber), a blend of carbon fiber, Kevlar, and aluminum filaments, ideal for cyclists seeking maximum stiffness and lightness. The base is made of long-fiber carbon for Nack rails. These materials offer an excellent balance between stiffness and comfort.
