Fi'zi:k launched the first Aliante in 1999. During the intervening fifteen years, it has become one of the most loved and favored saddles in the world, by both pros and enthusiasts alike. 2014 marked a milestone in the evolution of the Aliante with the launch of an all-new sleek profile. Boasting a TWIN FLEX Carbon shell, it offers unprecedented comfort and a low weight. Going from Curvy to Skinny, the new Aliante delivers a sharp aesthetic.Aliante R1 is for The Bull: Rigid Spine. If you have a relatively low degree of spinal flexibility (more than 90 degrees between your straight legs and back when bending over as far as you can, keeping your legs straight, and shoulders' width apart), you are a Bull. Your degree of spinal flexibility will top out quite quickly when attempting to adopt the performance position. For this reason, you will rotate your pelvis fully. You will benefit from the increased curvature (support) of the Aliante shape.- Shell: Composite Carbon with co-injected nylon Twin Flex 'sweet spot' at the center- Cover: Thermo-welded microtex - Black/black (regular), black/black (large)- Rail: fi'zi:k carbon braided rail (7x9mm)- Scuff guards on either side towards rear of saddle- Integrated Clip System: Yes- Length: 265mm- Width: 142mm (regular) or 152mm (large)- Weight: 175g (regular) / 180g (large)
