Fizik Transiro Aeris Short Distance R1 Light Saddle Sprint-ready, aero-optimized. The Fizik Transiro Aeris Short Distance R1 Light is built for time trialists and short-course triathletes who need maximum support and stability in the forwardmost aero position, without carrying extra weight. Injected EVA foam padding is thicker at the nose where the pressure is greatest, and slimmer at the sit bones for a firmer feel when rising out of position. A pressure-relief cutout transitions progressively into a channeled nose for added comfort, while a grippy surface texture keeps riders locked in position through hard efforts. Carbon reinforced nylon shell and 7x9mm carbon rails keep the whole package light without sacrificing stiffness.
