Aero-Optimized Tri Saddle with PAS Precision

Overview

The Prologo Dimension Tri Nack 143 Saddle is purpose-built for triathlons and time trials. Designed to support aggressive aerodynamic positioning, it allows riders to maintain high power output comfortably, even over extended race distances.

Optimized PAS Channel For Blood Flow: The redesigned PAS channel features modified width and depth to improve blood circulation and reduce numbness. It minimizes excessive pressure in sensitive areas, helping you stay focused and efficient in the aero position.

Proven Performance Gains: Track and wind tunnel testing with leading professional teams have demonstrated measurable gains of 5–8% in performance. The saddle is engineered to enhance power delivery while maintaining stability during sustained efforts.

Enhanced Variable Density Padding: Variable density foams, increased by 15% at the upper section and nose, expand the support surface area. This design distributes pressure more evenly and improves support in the antero-ischial area when riding in maximum aerodynamic posture.

Ultra-Light Nack Rail Construction: The Nack rail is made from nano carbon fiber for maximum rigidity and minimal weight. Combined with a long-fiber carbon base, it delivers exceptional stiffness and race-level efficiency.

The Prologo Dimension Tri Nack 143 Saddle delivers aerodynamic comfort, optimized pressure relief and elite-level performance for serious triathletes and time trial specialists.
