The Kurve saddles are comfortable not because of inches of padding but because of a correct profile and a flexible upper moving as you move and absorbing vibration out of the road.
There are 3 Kurve saddles, the one for you is determined by Fizik's Spine Concept:
Fizik Spine Concept: The idea that the flexibility of a rider's legs and back dictates how they sit on the bike and therefore what saddle would be comfortable for them. The measure for this is whether you can touch your toes and if not how close you can get. The most flexible riders, those who can touch their toes, should look at the Snake range of saddles. For those a bit less flexible, if your lower back is approximately 90 degrees to your legs when trying to touch your toes, the Chameleon range is for you. The Bull saddles are for those who sit most upright on their bike or are the least flexible. Use the image below as a guide:
Re:Flex Base
The entire base of all Kurve saddles is a sensory receptor that responds to the body in motion, mirroring its every twist and turn. The Re-Flex construction is made of thermoplastic composite materials using long filament composites in specific alignments. The result is reactive: the saddle follows the movement of the rider’s contact points, optimising the interaction between rider and saddle.
Wing Flex™:
The Wing Flex™ shell flexes downward in the critical area where the inner thighs contact the saddle. Whether the rider has big or small thighs, or a wide or narrow pelvis, the saddle adapts perfectly to the rider.
Mobius Rail™:
The design of the Kurve saddle employs a new type of aluminium supporting rail, The Mobius Rail™. Mobius is a circular rail construction that has no beginning and no end. Made from cold forged 2014-T6 alloy aluminium it provides the rail and shell with greater flexibility and support. Unlike a traditional saddle rail, the potential pressure points caused by the rail insertion areas are eliminated.
Tuner
There are 2 different tuners – soft and hard. This interchangeable tension system allows the rider to customise their flex. The rider can personalise the saddle tension by simply changing a screw-on insert.
