Fizik Transiro Aeris Long Distance R3 Saddle

The Fizik Transiro Aeris Long Distance R3 Saddle was built around a simple truth: in triathlon, the saddle you're on for hours shapes everything that comes after — including how well you run. The split-nose design relieves pressure on sensitive areas while the thicker nose padding addresses where triathletes actually sit when in an aggressive, forward aero position. A nose rail loop is included to correct for postural asymmetry over extended efforts — a small detail that matters more the longer you ride.

The R3 builds on that platform with 7x7 Kium rails — lightweight, stiff, and durable — paired with a carbon-reinforced nylon shell. At the rear, an integrated hydration mount lets you run a bottle cage in a clean, aerodynamic position, with the option to remove it entirely when it's not needed. At 135mm wide, the geometry is designed to support a tucked, forward-rotated riding position rather than an upright one — which is exactly the position this saddle was engineered for.
