Injected EVA padding bonds directly to the full carbon shell rather than using adhesive layers between separate foam and base components. The Vento Antares 00 from Fizik applies this manufacturing process to create low-profile cushioning that maintains structural integrity under pedaling loads without the weight penalties that come from thicker padding construction. The slight wave profile provides a reference point for position consistency while the tapered nose-to-wing transition supports fore-aft movement during varied efforts.

The high-modulus carbon shell resists flex under hard pedaling efforts to maximize power transfer rather than absorbing watts through material deflection. Oval 7x9mm carbon rails use Fizik's Mobius closed-loop design that eliminates the stress concentration points found where traditional rail ends attach to saddle bases. This continuous structure distributes clamping forces across broader contact areas rather than creating localized pressure zones that can lead to rail failure or creaking.

The flatter nose section compared to previous Antares generations provides a wider platform when you shift forward during climbs or into aerodynamic tuck positions. This increased surface area prevents the concentrated pressure that develops when balanced on narrow nose sections during extended efforts in forward-rotated positions. The ergonomic cutout channels pressure away from soft tissue based on medical analysis of blood flow patterns and nerve pathway locations rather than using arbitrary cutout shapes.... Read More
