Enjoy excellent support and comfort aboard Fizik's Arione R3. The composite Wing Flex shell moves with the rider's pedal stroke, offering unmatched comfort and an exceptional fit. The feathery carbon rails keep the overall weight down, and damp road and trail vibration. As always, it boasts the features and quality you expect from a Fizik: a Microtex cover with efficiency-enhancing thigh glides, and supportive, comfortable padding for on-the-road comfort.
