The Fizik Antares R3 Kium fills the gap between Fizik's most popular saddles, the Aliante and the Arione. The Antares is flat just like the Arione, but is a little wider like the Aliante--offering more support for the sit bones. Its light 195 gram weight and durable Kium rails make it a great racing saddle.
The Kium rails are standard 7mm round rails and will work with virtually saddle clamp. In case you are wondering, Kium is an alloy that is lighter and stronger than titanium.
The Fizik Antares has Fizik's proven pedigree of comfort, and it also has more padding than most other saddles in the same weight class. The Antares is a fantastic choice for riders who prefer a lightweight, flat and slightly wider saddle. The Antares is ICS compatible meaning a Fizik ICS saddle bag can snap onto the saddle for a super-clean installation--no more straps flapping around.
