Our longest distance, lowest profile, widest cutaway Butterfly with something extra: Poron XRD. Designed to take comfort up a notch for endurance riding, the Butterfly Century is engineered with a layer of Poron XRD shock absorbing material between the saddle's base and foam layers. This reduces road shock and allows for a thinner layer of foam and narrower overall saddle profile, without loss of rider comfort. A thin layer of gel and a larger center cutaway provides greater soft tissue relief. And finally, the Century has a seamless, synthetic Fibra-tek cover that reduces the incidence of high-cadence chafing. Made by hand in Italy.
