The Zero II from Prologo boasts a carbon fibre base & oval carbon rail that's not only amazingly low in weight but also ultra-tough for years of long-lasting use. Thanks to its active density padding, you can spend many hours in the saddle with outstanding comfort & control as it shares your body weight equally throughout the saddle. What's most impressive is the rails have been treated with the production process called Braided Carbon Rail (BCR) to obtain the perfect fusion & uniformity of several layer types & fibres & materials. As a result of its production process, this saddle has the perfect balance structure & resistance to penetration so you can push yourself to the max & take your riding up a notch.
