The Fizik Aliante saddle has become the go-to choice for comfort combined with light weight. Kium alloy rails are lighter and stronger than titanium. The Aliante features a slightly wider 142mm width and soft padding. A carbon reinforced frame contains a central carbon kevlar hammock to add a little give to the central portion of the saddle. The Aliante is a staff favorite at Excel Sports Boulder and several of us have ridden many thousands of miles on the Aliante model.
