Fizik's Aliante R5 Kium saddle blends the ideal combination of flex, form, fit, and strength to create a seat you'll enjoy riding for miles and miles. The carbon Nylon reinforced TwinFlex shell provides the strength and form of the Aliante, while the Kium rails add toughness and corrosion resistance with little weight penalty. The Microtex cover is rugged enough for daily use, too, so you get all the miles you can handle and then some. Its curvy design is more than just pretty looks: the wide rear of the saddle provides a perfect platform for your body weight, while the tapered middle and front are ideal for your natural pedal stroke. Take on your pavement ambitions astride the Aliante.
