The Fi'zi:k Men's Antares R3 Open Sadle is a performance road saddle for riders who want a medium saddle profile and a cut-out to avoid pressure and numbness. It features a composite Carbon-reinforced nylon shell and a light, strong, corrosion-resistant K:ium rail. A Comfort Core foam layer beneath the neat, durable Microtex cover provides comfort, which is enhanced by the full anatomic cut-out that avoids pressure on the rider’s sensitive soft tissue and ensures that all weight is correctly supported across the whole surface of the saddle.
