The Nago Space is a unisex semi-round saddle that is ideal for medium to long distance, road and off road riding. It offers unbeatable versatility for riders who like a choice of riding position. The Prologo Space technology has many benefits. It provides the maximum ergonomics, by using a wider central tunnel than is normally found in standard PAS saddles, helping to eliminate pressure spikes and numbness. The Space saddles have an increased width of between 141/143mm to 147mm, making it much more comfortable when on the bike.The Nago saddle uses Prologo's ESD technology. Ergonomic Shape Design is where Prologo have identified a new ergonomic design for the centre of the saddle, which allows more space for your legs and an overall better cycling position. Further to this, the ESD reduces the friction of the quadriceps against the body of the saddle.The saddle also has Active Density Technology which combines 3 foam densities with a variable stiffness base. It's structured in different areas using 3 related foam densities.**High Density** - This is on the rear of the saddle and it gives a stable support of the ischial bones.**Medium Density** - This is in the middle of the saddle and it reduces the pressure on the pelvic area.**Low Density** - This is at the front of the saddle and it reduces pressure peaks in the body.**Specs*** Size: 273 x 141* Rail: Tirox 7mm* Cover: Microfibre* Padding: Light PU* Weight: 222g
