Fizik | Arione R3 K:ium

The classic long-and-flat Arione shape, built for riders who like room to move.

The Fizik Arione R3 K:ium is a performance road saddle built around the classic Arione profile: long, flat, and narrow through the nose, giving riders plenty of space to shift position and find their preferred power point.

Its composite carbon co-injected nylon shell uses Fizik’s Wing Flex technology to allow controlled movement where the thighs contact the saddle, while K:ium rails keep the construction light and durable. A Microtex cover finishes a race-focused design that became one of Fizik’s defining road saddle shapes.
