The Zero saddle has been designed with a flat shape perfect for fast road riding. 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.Using Prologo's C3 (Carbon Composite Compound) which is a technology that involves a carbon fibre monocoque construction, offering ultra-light performance that is structurally more solid than conventional materials currently used on the market. This innovative process allows the manufacturing of products that can be as little as 149g and increases the mechanical resistance over 13%. These features combined with the high density padding, allow C3 saddles to achieve a high level of performance and comfort. Making a saddle that has an incredibly light weight but maintains the stability and performance of a heavier saddle.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: 270x132mm* Rail: Nack Carbon 7x9.3mm* Cover: Microfibre* Padding: Light Foam* Weight: 146g
