Transiro Aeris LD R3 Saddle

What Our Gearhead® Experts Are Saying:

"This saddle does everything right for long tri races. The split-nose design relieves pressure in the TT position without forcing you into awkward posture. It stays comfortable, supportive, and totally secure, even on hour three in aero. This one’s built for real endurance athletes."

The Fizik Transiro Aeris Long Distance R3 is purpose-built for triathletes who demand pressure relief and aerodynamic efficiency in equal measure. At its core is a unique split-nose structure—two independently flexing halves that conform to the rider’s movement and relieve pressure where it matters most, enabling longer, more comfortable rides in the most aggressive positions.

Developed from biomechanical research and rider feedback, the Aeris R3 features Fizik’s Type-1 foam construction—denser at the nose to support prolonged aero efforts, softer and firmer in key areas to enhance control during transitions in and out of the saddle. The base shape distributes weight evenly, while the generous cutout promotes blood flow through hours of forward-positioned riding.

Integrated features like a rear hydration cage mount and a reinforced transition hook make this saddle as practical as it is performance-oriented. Designed to be fully UCI compliant and built for aerodynamic optimization, the Aeris Long Distance R3 empowers triathletes to ride stronger, race longer, and finish faster without compromising comfort.
