Hour six is as comfortable as minute 30 on Fizik's Kurve saddle. Featuring a concept that's more suspension than perch, Fizik uses a multi-layer, multi-material Reflex composite base with soft and firm areas. Combine this with rails that are shaped in a continuous loop and moved out from under the rider, and it effectively creates a hammock that conforms to the body. There's nothing resisting your movement, so pressure is evenly distributed at all times for maximum comfort. No worries if it's too soft or too firm; the amount of flex is customizable by changing an insert in the nose. This Bull model is the same shape as their Aliante saddle, and is compatible with Fizik's Integrated Clip System.
