- The Dimension Nack saddle is at the cutting edge of Prologo's vision. It's the result of intricate and careful analysis of every little detail, to make this the most advanced and anatomically comfortable saddle that has ever been made. The Dimension Tri saddle has been adapted for Tri by increasing the sitting area by an extra 2cm, for improved comfort. The Dimension name alone exemplifies just how important this project is, Prologo's task for this saddle was to create an innovative product in terms of design, size, comfort and performance. Thus, Comfort, performance, lightness and prevention of perineal area problems are its strengths. The Dimension has also been designed to be a truly unisex saddle, providing pressure relieving benefits to both female and male riders. The design and size are engineered specifically for comfort when on the drops and for aggressive riding. It's not just comfort that this saddle has to offer though. Top-end performance and lightweight components mean this saddle is just about ready for anything. At only 159g it's a lightweight and ergonomic saddle for high-end users. The increased 143mm width, helps to distribute the weight of athletes over a larger surface, ensuring greater comfort over a longer period of time, and a short nose (3-3.5cm shorter than a traditional saddle) to eliminate any sort of contact and pressure in the front area, especially when on the drops. The wide anatomical PAS channel runs through the saddle along its central axis, reducing the contact and compression of soft tissues and tendons. The PAS system, is a channel in the base of the saddle. The hole or channel helps to maximises blood flow and supports the pelvic area while also preventing pressure peaks. This is a system researched, designed and developed to eliminate pressure and numbness to areas that need it most. The PAS Technology is achieved by a particular anatomical design of the foam and base. The performance and durability are guaranteed thanks to the unchanged integrity of the base. The Dimension saddle uses a Nack rail which is a monocoque carbon structure. Prologo's R&D department has engineered the clamping area by using a specific nano carbon fibre technology named BRC (Braided Carbon Rail) in order to support an extremely high level of stress when the seat clamp is tightened. The Nack rail is Prologo's top level rail combining unbeatable stiffness with extraordinary lightness CPC: Connect Power Control: Prologo patented technology. The specially designed CPC surface features a mat of hollow cones of various heights and diameters, arranged for maximum benefits to the rider. These include optimised grip, shock absorption and air cooling. It also enhances blood flow through a massaging action, reducing numbness and tendon related discomfort. **Specs** * Size: 245x143mm * Rail: Nack Carbon 7x9.3mm * Cover: Microfibre * Padding: Light Foam * Weight: 159g
