When we look at the profile of the Prologo Nago Evo TI 1.4 saddle we cant help but admire its clean lines low profile nose & slender body. Wrapped tightly in a smooth microfiber cover the Nago Evo TI 1.4 screams fast right out of the box. The Nago Evo TI 1.4 is built around a featherweight carbon frame -- the skeleton of the saddle that supports the foam & attaches to the rails. This is molded with varying densities so that vibration reduction is built-in & so that the saddle flexes slightly under power. Multi-durometer foam is attached to the frame with firm support beneath your hips & lighter more forgiving foam at the mid-section toward the nose. While this saddle gets titanium rails Prologo saw fit to reinforce them with a nickel coating. This does add a few grams but also increases durability. The Prologo Nago Evo TI 1.4 is 134mm measured at the widest part.
