Ares KIum Rails Road Saddle

What Our Gearhead® Experts Are Saying:

"This saddle hits the sweet spot for endurance and aggressive riders alike. The long profile gives you room to shift your weight, and the Wing Flex zones are a game-changer if you’re looking for natural movement without losing power."

The Fi'zi:k Ares Kium Rail Road Saddle offers a race-bred platform tailored for serious road cyclists and endurance-focused riders. Measuring 300mm in length and 132mm across, the Arione provides a broader contact area and ample real estate for dynamic position changes during extended efforts or technical rides.

Its carbon-reinforced nylon shell keeps weight low while ensuring long-term rigidity and control under load. Wing Flex side panels give the saddle adaptive flex where your inner thighs interact with the edges—offering unimpeded movement while maintaining structural integrity through the pedal stroke. The Kium rails, a proprietary titanium alloy, add strength and vibration dampening with less weight than standard steel.

A Microtex suede cover enhances durability and water resistance, while high-density foam padding balances comfort and responsiveness. With over 85mm of rail adjustability, the Arione is easy to fine-tune to your cockpit setup. Ideal for riders who demand both versatility and race-level support, the Ares Kium Rail Saddle remains a staple on road bikes from crit racers to fondo grinders.
