Prologo Dimension NDR NACK

Dimension NDR is the flat saddle designed and developed for off-road use. While it guarantees exceptional comfort and high performance on rough terrain, it also proves to be perfectly suited for road cycling. Its ergonomic shape and reduced weight make this saddle extremely versatile and ideal for all disciplines, with no distinction between male and female riders.

Dimension NDR is developed and used by top professional teams around the world in cross-country and marathon mountain biking as well as in road cycling. It’s designed to meet the demands of all types of cyclists.

Anatomical Shape

The 3 mm extra padding ensures better vibration absorption, while the rounded seating area supports the rider's natural pelvic rotation. The shorter nose (35 mm shorter than traditional saddles) eliminates numbness and pressure peaks during high-intensity efforts.
The V-shape design of the Dimension NDR ensures more precise positioning on the saddle surface. The advanced anatomical center allows for a more forward seating position. The wider seating area (143 mm) enables better bodyweight distribution. Its flat anatomical shape supports a more aggressive and aerodynamic riding posture, making it ideal for riders with high pelvic flexibility.

Technologies

The Dimension NDR features an enlarged PAS (Perineal Area System) channel, which reduces pressure on soft tissues, tendons, and blood vessels, helping maintain proper blood flow. The Side Protector provides added protection from scratches and damage in the event of a fall — small details that make a big difference.

The combination of a short nose and the PAS system ensures pressure relief and uninterrupted blood flow, providing comfort even in aerodynamic positions or during maximum power efforts.

Base and Rails

The Nack rail (Nano Carbon Fiber) is composed of carbon fiber, Kevlar, and aluminum filaments, ideal for cyclists seeking maximum stiffness and lightness.
