Fizik Aliante R5 Saddle with K:ium Rails
The Fizik Aliante R5 saddle with K:ium rales uses a flex zone to keep the pressure low while you ride hard.
The Twin Flex shell technology of the Fizik Aliante R5ium K:ium Saddle offers full-length pressure relief from the saddle's nose through the flank. The outer shell is Carbon Nylon reinforced while the inner "flex zone" uses carbon and Kevlar for pressure relief, and reinforced with a Microtex cover. K:ium alloy rails keep the weight to a minimum and resist seatpost clamp forces.
