Transiro Aeris LD R3 Saddle

What Our Gearhead® Experts Are Saying:

"I switched to the Aeris Long Distance R3 for my Ironman build and it made a huge difference in comfort during long aero efforts. The split-nose design relieves pressure without feeling unstable, and the thick nose padding lets me stay tucked for miles. It's dialed for real-world race use."

Long-course racing demands everything from us—focus, power, and unrelenting comfort. That’s why we trust the Fizik Transiro Aeris Long Distance R3, engineered for triathletes who spend hours in the aero bars and need lasting support through every pedal stroke. Born from research in bike fit and aerodynamic efficiency, this saddle reimagines comfort where it matters most.

The Aeris R3’s defining feature is its split-nose construction, designed to relieve pressure on soft tissue while maintaining the stability we need to produce consistent power. The independent halves of the nose flex naturally with our pedaling, while the Type-1 padding is thicker up front for aero-position comfort and slimmer out back for firm sit bone support. The integrated transition hook and optional hydration link reflect the saddle’s all-race-day focus. Whether it’s a sprint to T2 or the back half of a 112-mile ride, the Aeris is built to go the distance.
