The Fizik Arione Versus X Kium Rail Saddle is nearly the same as the standard Arione Versus, but features a 20mm recessed, deeper centre channel. The 2cm wide channel can provide relief to sensitive areas & the Versus model incorporated it into their well-proven Arione model. The channel is created with extra padding for more cushioning as well as centre relief. The flat, supportive shape & Wing Flex comfort have long made the Arione a favourite with all type of riders- from racers to weekend warriors. The Arione has contemporary yet timeless style that can only come from Italy & performs as well as it looks. One of our most popular saddles, the Arione uses Wing Flex technology for a saddle shell that is stiff yet flexible for optimal performance & comfort. The Arione Versus X Kium is ICS compatible, meaning a Fizik ICS saddle bag can snap onto the saddle for a super-clean installation--no more straps flapping around.
