Prologo Nago R4 PAS Saddle

The shorter 245mm length is designed to encourage a more aggressive, forward-leaning posture. By reducing the overall footprint, it helps you maintain a stable position while pedaling efficiently without the nose of the saddle getting in the way of your inner thighs.

Yes, the Tirox rails feature a standard 7x7mm round profile. This makes them compatible with the vast majority of seatposts on the market, including those with standard two-bolt or single-bolt clamping mechanisms.

Variable-density foam provides firmer support where your sit bones need it most, while offering softer cushioning in areas where you need more comfort. This targeted approach prevents the saddle from feeling too squishy or too hard, balancing performance with long-ride comfort.

The PAS (Perineal Area System) channel is specifically engineered to eliminate pressure spikes in the perineal zone. By removing material from the center, it promotes better blood flow and reduces numbness, which is particularly helpful during long hours in the saddle.

The long-fiber carbon base is significantly stiffer and lighter than standard nylon or plastic shells. This rigidity ensures that your power transfer is more direct, while the carbon fibers still allow for a degree of controlled flex to absorb road vibrations.
