The Aliante Gamma is one of fi'zi:k's three Spine Concept Mens Road Saddle shapes. Among these three shapes, the Aliante shape is the widest and most longitudinally waved. The Aliante Gamma is designed 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 of the Aliante shape, which provides support. Here are the specifications for the Aliante Gamma:- Shell: Nylon Carbon Reinforced with Twin Flex 'sweet spot' at the center- Rail: K:ium- Scuff guards on either side towards the rear of the saddle- Integrated Clip System: Yes- Length: 265mm- Width: 140mm- Weight: 259gNote: The product is categorized as 'Road Saddles'.
