An ideal saddle for medium and short distance riding where a frequent change in position is necessary. The flat shape in conjunction with the rigid saddle shell give a very direct ride feeling.The flat shape is most suited for cyclists with good lumber flexibility and allows easy movement of seating position, making it ideal for experienced riders that like to change position to really put the power down.The Zero 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.**Specs*** Size: 278x134mm* Rail: Nack Carbon 7x9.3mm* Cover: Microfibre* Padding: Light Foam* Weight: 188g
