If you have an intermediate degree of spinal flexibility (approximately 90 degrees between your straight legs and your back when bending over as far as you can, keeping your legs straight a shoulders' width apart), you are a chameleon.

Versus X took the pressure relief chancel concept of fi'zi:k's successful Versus saddles and expanded it further with a channel design that has a width up to 30mm and depth up to 20mm for optimal pressure relief. For 2016 the foam compound is softer and the edges of the channel are more rounded to improve comfort and relieve the sensation of pressure.

K:ium Rails

K:ium is a fi'zi:k proprietary rail formulation. It's the combination of a particular metal alloy, a specific tubular design and a special finishing process which increases fatigue performance on the rail surface. Fact: 8% weight reduction compared to solid titanium. k:ium features a high strength-to-weight ratio grade and high corrosion resistance.

Wing Flex

Wing Flex shell has engineered flexibility along the edges where the inner thighs contact the saddle. By allowing this area to flex, the rider can achieve a full range of leg movement in a wide range of riding positions. Wing Flex allows the saddle to adapt to the rider rather than the rider having to get used to the saddle.

Integrated Clip System

Integrated Clip System is an integrated interface in the saddle's base to allow quick attachment and removal of Integrated Clip System accessories such as the Fi'zi:k saddle Pa:k and Blin:k light . It is a clean, easy, fast and secure attachment that does not require any tools.

About Fizik

Fi’zi:k is the premium, racing brand of Selle Royal S.p.a. It's name is synonymous with the shape and form of the human body; hence the intuitive association with products that are contact points between riders and their bikes.The humble origin in 1998 stemmed from a vision to improve rider performance by creating superior saddle comfort. Today’s Spine Concept™ provides a guideline to help riders find their most comfortable saddle. Integral to this comfort is the design collaboration with professional athletes and the fact that each saddle is 100% “fatto a mano” (hand-made) in Italy.
