Prolog Nago R4 PAS TiroX 137mm road bike saddle

Designed with input from professional riders competing in the Tour de France, the Prologo Nago R4 saddle is engineered to perfection. It offers excellent freedom of movement and pedalling efficiency in all positions thanks to its 245 mm length, T-shape and forward-shifted anatomical centre. This saddle has a narrow width of 137 mm to suit cyclists with a smaller sit-bone width. The semi-round ergonomic shape is ideal for cyclists with average pelvic rotation flexibility.

The Prologo Nago R4 PAS TiroX 137mm is also comfortable thanks to its latest-generation variable-density foam, which ensures good support throughout all phases of pedalling. Prologo’s PAS system features a wide central channel with cut-outs to eliminate all pressure points during exercise. The shell is made from long-fibre carbon, a lightweight and rigid material. The TiroX steel rails offer an excellent balance between weight and strength whilst providing better vibration absorption.
