Prologo Nago R4 Tirox 137mm road bike saddle

Available in a cut-out version, the Prologo Nago R4 saddle also comes in a full-cover version for cyclists who prefer a classic saddle. This features three completely independent sections made with variable-density foam for comfort. Beneath the central section, the Active Base system combines all the benefits of a closed saddle – protecting your cycling shorts from the rain – with those of an open saddle.

The Prologo Nago R4 Tirox 137mm offers good freedom of movement and pedalling efficiency thanks to its 245 mm length, T-shape and forward-shifted anatomical centre. The semi-round ergonomic shape is ideal for cyclists with average pelvic rotation flexibility. The shell, made from long-fibre carbon, is lightweight and rigid. This saddle is based on TiroX rails made from lightweight alloy steel, a material that offers an excellent balance between weight and strength whilst being less rigid and more comfortable.
