Fi'zi:k Aliante R3 K:ium Saddle. A favorite among the professional peloton, and with good reason, the Fi'zi:k Aliante R3 K:ium Saddle strikes an optimal balance between comfort and weight. Italy's Fi'zi:k introduced the first Aliante in 1999 and in the subsequent years it has become one of their most loved and preferred saddles. 2014 marked a milestone in the evolution of the Aliante with the launch of an all new, sleek profile. It's built off the 'Bull' family of Fi'zi:k's Spine Concept system, so it's designed around cyclists who are less flexible and therefore need more cushion for soft tissue areas as they roll forward on the saddle. The K:ium rails are constructed of an alloy lighter than titanium, and they're plenty stiff so they won't deform under power.
