The Vento Antares R3 uses a low-profile road shape with a carbon-reinforced nylon shell and hollow Kium rails. Wingflex side edges accommodate leg movement, while double-density foam is firmer beneath the sit bones and softer toward the nose.
This black selection is 140mm wide and 268mm long, with a listed 7 x 7mm rail profile. It uses conventional foam, separate from the Adaptive 3D-printed version. Compare the dimensions and clamp requirements with the saddle you are replacing.
