The Antares R3 Open is one of the leading road saddles for riders who prefer a medium saddle with an ergonomically shaped cutout to avoid pressure and numbness. It is handcrafted for full comfort using advanced technologies and materials. Like all fi'zi:k road saddles, the Antares R3 Open is lightweight, flexible, and dynamic. The design is created by professionals for professionals and is ridden by professionals. The mobility of the spine and pelvic rotation are directly related to saddle comfort and determine which saddle and components fit individually. "Chameleon riders" with moderate body movement and low pelvic rotation while pedaling are supported by the neutral, dynamic saddle profile to find their individual power spot without sacrificing comfort. The ICS on the underside of the saddle allows for quick attachment and detachment of accessories using the ICS system, such as the fizik saddle bag or the blinking light. A simple, easy, and fast system for the secure, tool-free attachment of accessories.
