The Fizik Arione R1 saddle is part of the further developed Spine Concept. Before, this just looked at the flexibility of your spine, but now it takes the way you ride into consideration as well. The rotation of your pelvis is essential to determine whether a saddle suits your needs or not. There's now both a Regular (130 mm) and Large (142 mm) version available of the Fizik Arione R1. The faster you ride, the lower the pressure gets on the saddle, requiring less surface area for support.
The Fizik Arione R1 has been designed for the so-called Snakes. The Snake is a rider with a flexible back who feels comfortable riding low on the drops and needs a narrow saddle. The Cyrano Snake Bars with its deep drops and the Arione saddle are made to suit this rider's needs .The Fixik Arione R1 is an extremely rigid and lightweight saddle. This is due to the carbon shell, the Wing Flex technology, and carbon braided saddle rails.
This saddle has a flat back which makes it suitable for riders who remain stationary on their saddle and don't slide around during their ride. Since this is a flat saddle, it better supports these riders than a round saddle would.
This is a completely flat saddle which provides you with plenty of freedom to move around. The shape is suitable for riders with a high degree of flexibility in their spine. People with a flexible spine have little trouble rotating their pelvis, meaning they need little to no support to get into the proper cycling position.
