Transiro Aeris SD R1 Saddle

What Our Gearhead® Experts Are Saying:

"I’ve tried a lot of TT saddles, but the Aeris R1 stands out with its smart nose padding and aggressive fit tuning. It gives me a firm, stable perch for power without any numbness or fidgeting."

The Transiro Aeris Short Distance R1 is engineered to meet the demands of elite time trialists and triathletes chasing aero gains without compromising comfort. Designed in collaboration with bike fitters and aerodynamic researchers, this saddle targets short-course performance with a highly stable, supportive platform.

At the core is Fizik’s type-1 padding, thicker at the nose where athletes spend most of their time in the tuck and slimmer at the rear for a firm platform during transitions. A central pressure-relief cutout and progressive channeling keep soft tissues comfortable on sustained efforts. The short, broad nose gives riders the confidence to stay in an aggressive position without sliding forward or losing support.

A 7x9mm full carbon rail system keeps the saddle lightweight while providing broad adjustment options within UCI rules. With an optional integrated bottle mount, the Aeris R1 is transition-ready and race-tuned. Whether you're smashing sprint triathlons or attacking TT stages, this saddle offers the aerodynamic performance, comfort, and engineering excellence to support your podium goals.
