Behold the comfortable, lightweight, race-hungry Tundra M3 with K:ium rails… made for the Snake! What exactly do we mean by Snake? Snake is one of the three animals used by Fizik to symbolize their Spine Concept flexibility system. The “Snake” uses the entire length of the saddle, flexes easily and naturally to accommodate changing positions, and genital compression isn’t an issue. Sounds like the relationship you have with your saddle? If so, then you just might be a “Snake.” The fiberglass thermoplastic composite shell is stiff yet flexible, preventing saddle sag. The extended saddle length provides more riding position options and the Wing Flex™ technology allows the shell to flex downward in the critical area where the inner thighs contact the saddle allowing for more efficient, full-range movement while pedaling. This combination offers riders comfort, health and performance benefits. On top of it all, Fizik’s unique integrated clip system is a built-in clip receiver for attaching Fizik accessories, such as bags and lights, for simplicity, practicality, and security.
