For maximum comfort and performance. The "OPEN" series incorporates an open area that cyclists couldnt completely wipe away discomfort due to pressure and other discomfort with an existing fizi:k performance load saddle. Fizi:k has never launched perforated saddles except for female specific models. We recommend the channel (grooves) and design model because it reduces rigidity, and bends will not demonstrate performance, and reduces strength and durability. The new open-hole saddle "OPEN" has been utilizing fizi:k saddle manufacturing experience and carbon reinforced nylon shell, which is a base material such as LUCE, maintains the same flexibility and strength as the existing model, and increases the rigidity of the saddle itself, minimizing the strength of the open area. ■ ARIONE is a saddle that is highly flexible for the body and does not have pelvis rotation during pedaling (Spine Concept: Snake) performance. ■ Longer than other fizi:k road saddles, easy to move from nose to tail, you can find your power in a variety of positions. Combining an anatomical cutout shape with advanced technology, materials and aesthetics, the ARIONE R3 OPEN is a performance load saddle for riders who need a flat saddle profile and cutout to avoid pressure and numbness. ■ ARIONE R5 OPEN features a carbon reinforced nylon shell and a robust and lightweight S-alloy rail. The Comfort Core Foam layer beneath the beautiful and durable Microtex cover provides comfort, avoiding the pressure on the riders sensitive soft tissue, and anatomical cut-outs ensure that all weights are supported precisely across the front of the saddle. ■Shell: Carbon reinforced nylon shell ■Rail: S-Alloy ■Cover: Microtex ■Size: 11.8 x 5.1 inches (300 x 130 mm) (Regular), 5.6 inches (142 mm) (Large) ■Reference Weight: 8.5 oz (249 g) (Regular), 9.5 oz (261 g) (Large) ■ICS clip system compatible.
