When Fizik introduced its first saddle, the Arione, it rocked the saddle world. Now they have done it again with the Kurve saddles. But rather then reinvent the saddle, Fizik takes a cue from the best saddles of old and updates the technology to work with modern materials. They’ve put a premium on comfort above all else, and the result is the Kurve platform. The Fizik Kurve saddles feature a two part system that is designed to give you unprecedented comfort on the bike.
It starts with a 3 layer carbon fabric base (or shell) that has adjustable tension (read: flexibility/firmness) so you can tailor the saddle feel to your preferences. The 3 layer fabric, called Re:Flex Dynamic Interface, is designed with only 1 layer beneath more critical parts such as your sit bones and perineal nerve so that it flexes easily under those areas. The second part of the system is the Mobius one-piece, forged, aluminum rail. The Mobius rail is designed as a spring held in compression by the base and the “Tuner” you choose (more on that in a moment). You therefore have the flexing of the base and the springing of the rail complementing each other to provide comfort. The Mobius rail holds the base at the very ends of the saddle. This is a key design point. Most other saddles, including Fizik’s, have the rails attached to the base underneath the sit-bones area, which consequently increases pressure there. By supporting the saddle at the very front and rear of the base, the entire saddle is able to flex and move with your body.
The Kurve saddles are tunable to your preferences by placing soft or hard “Tuners” at the nose of the saddle. The Tuners control the tension of the base. Higher tension equals less flex. Lower tension equals more. This is old technology and Fizik is keen to borrow it from sister company Brooks and implement it in a modern design.
The most common Fizik technologies have also found their way in to the Kurve saddles. Wing Flex technology allows full unhindered movement for your legs and a supple microtex cover provides that little extra bit of softness over the base. Padding is kept to a minimum since comfort is derived primarily through the flexing of the base.
Though the price may scare some away, the reviews around the cycling world so far have only given high praise. With an understanding of the Kurve saddle design, it’s not hard to see that most everyone could benefit from riding one. They currently come in Bull, Chameleon, and Snake models. Each corresponds to the Aliante, Antares, and Arione, respectively.
