The Arione Tri 2 K1 with 7x9 Braided Rails is the lightest tri-specific saddle from Fi'zi:k. Its shape is optimized for the TT/tri position in order to provide support and comfort in the most powerful riding position. Fi'zi:k's Arione Tri 2 K1 uses a flexible thermoplastic composite Wing Flex shell that ensures that the sit bones are properly supported. However, where Wing Flex differs from the competition is that it does this without inhibiting pedal stroke or causing inner-thigh irritation. That theme continues to the wide and flat nose as well, where shape plays a comfort role along with the cover. Furthering the elimination of abrasion, Fi'zi:k's Microtex cover, a synthetic leather akin to microfiber, lacks seams where saddle position adjustments commonly occur. This way, both hot-spots and inhibited movements are prevented. The cover material is not only durable for the extensive miles that the Arione Tri 2 K1 will endure, but it's also easy to clean. Underneath the saddle, Fi'zi:k employs its light and strong carbon braided rails. For added strength and tuned vibration dampening, the weave is filled with unidirectional carbon fibers. And while this adds to the level of comfort, it also enabled Fi'zi:k to keep the Arione Tri 2 K1 under 200g. The Fi'zi:k Arione Tri 2 K1 with 7x9 Braided Rails is 132mm wide and available in the color Gummy White/white.
