The Prologo Nago Evo saddle with the Active Density technology offers excellent rider comfort. The Nago Evo is distributed into 3 zones becuase of the Active Density. The seating area of the saddle is firm and rigid. This ensures you're both comfortable and efficient when pedalling. The central portion of the saddle, which is prone to pressure, is more flexible and less rigid. This decreases the pressure on your soft tissue, improving your comfort. The front of the saddle has soft padding but is still rigid. When you're really going flat out, the soft padding will alleviate some of the pressure but you don't have to sacrifice efficiency.
This saddle has a semi-round rear part, making it highly suitable for riders who move a little while they ride and whose hips rock a little from side to side. The semi-round shape provides plenty of support for those riders while maintaining sufficient freedom of movement compared to a flat saddle.
This is an S-shaped saddle, meaning it’s raised at the back and lowered in the middle. This S-shape makes it possible for people with an inflexible spine to assume a proper riding position. This has to do with how easy these riders find it to rotate their pelvis. People with an inflexible spine often have more trouble rotating their pelvis, meaning they could use some extra support.
