Flat profile geometry defines the Arione platform from Fizik. At 300mm long, the saddle provides more fore-aft adjustment range than standard-length designs, which matters when you're dialing in position on a new bike or experimenting with saddle setback to optimize power delivery. The flat shape runs from nose to tail without the curved transitions some riders find restrictive, and the narrow nose design reduces inner thigh interference during the pedal stroke.

Carbon-reinforced nylon construction forms the shell using Fizik's thermoplastic composite process. Wing Flex technology allows the outer edges of the saddle to flex downward where your inner thighs contact the surface, reducing restriction at the top of the pedal stroke without compromising support in the center channel. This lateral compliance works with the flat profile to accommodate position changes during long efforts, letting you shift weight forward for climbs or back for recovery without the saddle geometry fighting your movement.

Braided carbon rails handle clamping forces through a sleeve of woven carbon fibers surrounding unidirectional carbon strands. The 7x9mm oval rail dimensions require compatible seatpost clamps, and some posts need an adapter kit to properly secure the narrower rail profile. The rails include millimeter markings for precise fore-aft positioning, which helps when you're transferring measurements between bikes or documenting your fit coordinates.... Read More
