The Gobi is a mountain specific saddle for riders who fall in the middle of Fizik's flexibility range. The shape is relatively flat with pedal friendly WingFlex technology. The shell has a built in, controlled flex designed for both comfort and pedal efficiency. Tailflex works the same way, with an engineered flex zone that's anatomically designed for comfort. The majority of the support is located beneath the sit bones, and a subtle hollowed area relieves pressure on the soft tissue areas.The Gobi M1 is built with braided carbon fiber rails and then wrapped with another layer of carbon fiber cloth for additional durability. The rails are oval 9mm tall by 7mm wide. This strengthens the rails while assuring compatibility with almost any seatpost. They are also roughly 80 grams lighter than their Kium siblings. Fizik finished the saddle with its tough Microtex cover, then added slick thigh glides that make position adjustments easy.
