The Fi'zi:k Aliante Versus X K:IUM Road Bike Saddle combines the proven Spine Concept technology with a larger central relief channel. A 20 mm deep channel design allows a greater pressure relief maintaining the stiffness and durability of a solid base saddle.

The Aliante shape is the wides most longitudinally waved of fi’z:k’s trio of pro-cyclist-developed Spine Concept models. The Aliante Versus X K:ium adds the Comfort Channel along the length of the saddle. It features a carbon reinforced Nylon shell for support with optimized stiffness to-weight construction -- with Wing Flex technology which enables flexibility where your thighs meet the saddle -- and an alloy K:ium rail for light weight and strength.
