The Fizik Antares is great if you like a flatter saddle like the Arione, but long for a bit more width, more like the Aliante. In fact, the Antares nestles into the middle ground between the two. In comparison to the Aliante, the sweet spot is bigger, meaning you can shift around on the saddle more and still be comfortable -- on long climbs, in the drops -- as your body position reacts to the road. The Fizik Antares Versus K:ium Saddle is a special version designed primarily for comfort without giving away anything with regard to your performance.
The Versus range of saddles makes use of thicker foam than their standard Fizik counterparts. It is specifically shaped to provide more padding for your sit bones to keep them from getting tender on long rides. For your soft tissue, there's a channel that runs the length of the saddle top. It provides pressure relief and helps to improve airflow. Versus marks the first time we've seen a channel in Fizik saddles. The designs have been in development for quite some time, but they've just determined the shapes to be ideal through long-term laboratory blood flow analysis and thermal mapping of multiple groups of test subjects.
Most saddles are barely 40mm wide at the nose, but the Antares is a bit different. Its nose width is 45mm, giving it added comfort if you're in the drops or if you typically ride with a significant saddle-to-bar drop. Another element that adds to the cush, the comfort, the give, of the saddle is the carbon-reinforced nylon shell. It flexes gently across the entire span between the front and back ends where the rails support the shell rather than being stiff in some places and forgiving in others.
The K:ium (pronounced "Koom," rhymes with zoom) rails is an evolutionary step forward from titanium rails. They're 8% lighter, have greater strength to weight ratio, and damp more vibration. The damping is thanks to the Silicium. The shiny look is thanks to the chrome content. The chrome increases corrosion resistance, which helps with overall durability.
The Fizik Antares Versus K:ium Saddle comes in Black only. The length of the Antares is 274mm, and it's 142mm at its widest. It possesses Fizik's Integrated Clip System (ICS) so you may attach a Fizik light or saddle bag directly to the saddle without the need for straps. The Microtex cover is perforated for airflow, and since it's a synthetic material, it's antimicrobial, fade resistant, and won't stretch or crack.
