Dimension R2
Dimension R2 is Prologo’s new high-performance ergonomic saddle, positioned at the top end of the Dimension family, one of the most popular ranges on the market in recent years. A compact, multidisciplinary saddle measuring 245x143 mm, it's perfect for road, gravel, and XC/marathon MTB use. Designed for both professionals and demanding enthusiasts, it targets riders seeking maximum performance and premium-level components.
Prologo’s ongoing pursuit of peak performance—combined with continuous improvements in design and materials—has made it possible to further evolve an already cutting-edge saddle and create the lightest Dimension ever. Weighing just 135 grams, it is 13% lighter than the previous Dimension 143 model.
Anatomical Shape
The V-shape design of the Dimension R2 minimizes unwanted movement and ensures precise rider positioning on the saddle. Its forward-positioned anatomical center allows riders to comfortably sit further toward the front. The flat anatomical profile promotes a more forward and aerodynamic position, making it ideal for riders with excellent pelvic flexibility.
Technologies
The Dimension R2 features a completely redesigned nose, now 40 mm wide—a 30% increase over the previous model—and with a more rounded side profile. This new design was developed to further enhance comfort, especially during intense pedaling efforts. The PAS (Perineal Area System) is an open central channel designed to eliminate pressure peaks and numbness, improving blood flow and comfort.
A new EVA foam allowed Prologo to reduce the rear padding thickness by 1 mm, a 20% decrease compared to the previous model. This weight reduction was achieved without compromising support or comfort.
Base and Rails
The base is made of long-fiber injected carbon, a material offering an excellent balance of stiffness and comfort. The Nack rail (Nano Carbon Fiber) is made from a blend of carbon fiber, Kevlar, and aluminum filaments, ideal for riders seeking maximum stiffness and lightness.
