Used for 4 rides before realising it doesn't suit me. Technical details of the item below. Kium is some sort of metal alloy.
Fizik Antares R3 Versus Evo Kium Road Saddle
With full-channel comfort and advanced technology, materials and craft, Antares R3 Versus Evo is a performance road saddle for riders who want a medium saddle profile and a pressure relief channel. Designed for Fiziks Chameleon style riders.
Antares R3 Versus Evo features a composite Carbon-reinforced nylon shell – with Wing Flex technology which enables flexibility where your thighs meet the saddle – 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-length comfort channel that reduces pressure on the rider’s sensitive soft tissue and ensures that all weight is correctly supported across the whole surface of the saddle.
