The Fizik Arione R1 Saddle is popular with the pros because of both the classic shape and cutting-edge ways Fizik keeps the saddle light.

The Arione is the longest and flattest saddle of the Fizik lineup. The Large Arione measures 300mm long by 142mm wide and weighs 175g. The Regular Arione is not only long, but narrow, going out to 130mm wide at the widest. It weighs 165g.

In the realm of Fizik’s Spine Concept, the Arione shape is for those with high body flexibility and no pelvic rotation while pedaling. Whether or not you buy into their concept is up to you. Others like the flat shape because they prefer to move around freely on their saddle and like the long nose.

The shell is a carbon composite that is fairly flexible laterally. This means that the rear of the saddle will move out of your way when you’re on it. They call this Wing Flex. The rails are carbon-braided and an almost-oval 7x9mm dimension, which drops weight and adds strength. The rails are marked to the millimeter for precision fitting. The cover is made of Microtex, a smooth, tough synthetic leather that wears well. There are actually three panels of Microtex, a main and two side pieces. The sides are also Microtex, but have a different finish. As with all Fizik saddles, the Fizik logo in the back detaches to reveal a mounting point for Fizik Integrated Clip System accessories, a line that includes both lights and bags.

The Fizik Arione R1 Saddle is comfortable and light.
