Most saddles with channels or cutaways rely on material being removed from the shell, but this can lead to excessive flex and premature failure. fi’zi:k’s VERSUS X saddles are designed for performance riding, making power transfer and durability very important. In order to build a saddle with a deep channel that remains stiff and strong, VERSUS X saddles use a unique shell design with carbon-reinforced nylon construction. The VERSUS X shell is as stiff as a conventional saddle but with the added comfort benefits of a deep channel. On top of the shell is foam padding specially developed for the VERSUS X. Each VERSUS X saddle has a different combination of foam densities to fit the characteristics of different saddle shapes. VERSUS X technology is available in fi’zi:k’s Arione, Antares and Aliante shapes, with each shape suiting a different riding style. fi’zi:k’s Spine Concept categorizes riders according to their flexibility, from the most flexible Snakes to the least flexible Bulls. The different saddles are shaped accordingly. With the different shapes of the Spine Concept plus the VERSUS and VERSUS X channel options, fi’zi:k has a saddle to suit any rider.
