Ergonomic Shape & Riding Efficiency

V-Shape with Flat Profile

The Dimension NDR features Prologo’s signature V-shaped design, ensuring precise positioning and a stable riding platform. Its flat anatomical profile supports an aggressive, aerodynamic posture, making it particularly well suited for riders with high pelvic flexibility.

- Wider 143 mm seating area for improved bodyweight distribution

- Advanced anatomical center promotes a slightly forward riding position

- Short nose (35 mm shorter than traditional saddles) reduces numbness and pressure during high-intensity efforts

Enhanced Comfort on Rough Terrain

Extra Padding & Natural Pelvic Support

An additional 3 mm of padding improves vibration absorption, while the rounded seating area supports the rider’s natural pelvic rotation. This combination ensures comfort and control on uneven surfaces without compromising pedaling efficiency.

PAS Pressure Relief & Protection

Enlarged PAS Channel

The expanded PAS (Perineal Area System) channel reduces pressure on soft tissues, tendons, and blood vessels, helping maintain consistent blood flow during long rides or maximal power outputs.

Side Protector Technology

Integrated Side Protectors safeguard the saddle from scratches and damage in the event of falls or bike contact, small details designed for real-world off-road use.

Base & Rail Configurations

The Dimension NDR is available in multiple configurations to match different riding styles and priorities:

- Nack rails (carbon fiber, Kevlar, aluminum filaments) with a long-fiber carbon base for maximum stiffness and minimal weight

- Tirox rails (light alloy steel) with an injected carbon base for enhanced vibration absorption

- T4.0 rails (special chromoly steel) with a reinforced nylon base for maximum mechanical strength and comfort

Each version delivers an optimal balance of durability, performance, and ride quality.
