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 RailsThe Dimension Tri saddle is available in two versions: Nack rail (nano carbon fiber) with a long-fiber carbon base – designed for cyclists seeking maximum performance and minimum weight. TiroX rail (light alloy steel) with an injected carbon base – ideal for those prioritizing greater comfort and enhanced vibration absorption.
