Prologo Dimension Tri 143 Tirox Black Saddle with PAS Channel for Triathlon

The Prologo Dimension Tri 143 Tirox Black Saddle represents the pinnacle of ergonomic design and innovation in cycling components. Crafted with meticulous attention to detail, this saddle offers a perfect blend of comfort and performance tailored specifically for triathletes. Its increased sitting area by an extra 2cm provides enhanced support during long rides, reducing fatigue and allowing athletes to maintain optimal posture throughout their training or competition.

Designed as a truly unisex option, the Dimension Tri saddle balances anatomical precision with lightweight construction. Weighing only 179g, it combines durability with advanced features such as the wide 143mm width and a shortened nose to minimize pressure in sensitive areas. The saddle’s shape ensures stability and comfort when riding in aggressive positions, making it ideal for those who demand both speed and endurance.

One of the standout features of this saddle is its patented PAS (Perineal Area System) channel. Running along the center of the saddle, this channel reduces pressure on soft tissues, improves blood flow, and helps prevent numbness and discomfort. The TiroX rails, made from aerospace-grade alloy steel, provide the perfect balance of stiffness and lightness, ensuring excellent power transfer with every pedal stroke.
