Dimension TRI is Prologo’s saddle designed specifically for triathlon and time trials. A lightweight, high-performance saddle that allows riders to maintain an aerodynamic position and apply maximum power to the pedals—even over long distances.
Ergonomic Design
With compact dimensions (245 x 143 mm) and competitive weights (178 g for the Nack version, 225 g for the Tirox), this saddle is engineered for triathlon and time trial performance.
Its V-shape ergonomics provide excellent positioning and promote a more forward-leaning posture, improving comfort throughout every phase of pedaling.
Technologies
The updated PAS (Perineal Area System) channel, now optimized in both width and depth, improves blood flow and eliminates numbness and excessive pressure in the genital–prostate area. Track and wind tunnel tests, conducted with some of the world’s top professional teams, showed a 5–8% performance improvement.
The variable-density foams, increased by 15% in the upper and nose areas, enhance support surface area, evenly distributing pressure and offering greater comfort—especially in the antero-ischial region during full-aero positioning.
Bases and Rails
The rail is available in two versions. Nack (Nano Carbon Fiber): Made from carbon fiber, Kevlar and aluminum filaments, it is the perfect choice for those seeking maximum stiffness and lightness. Tirox (light-alloy steel): offers excellent vibration absorption and an outstanding strength-to-weight ratio.
The saddle base is made of long-fiber carbon for the Nack rail version, or carbon-reinforced nylon for the Tirox rail version.
