Product Details

Fizik Transiro Aeris R5 Short Distance Tri Saddle

The Aeris short-distance saddle is designed to provide maximum stability and support for time trialists and triathletes, offering an optimal platform for delivering power in forward, aerodynamic riding positions.

Innovation in bike-fitting analysis, along with research on cycling aerodynamics, led to a rethinking of triathlon and time-trial saddles. In a field where marginal gains are crucial, offering a saddle that allows comfort in the most extreme aerodynamic positions represents a significant leap forward in performance.

The short-distance version of the Aeris has been engineered to provide support and stability for athletes competing in time trials and short-course, no-draft triathlons. A pressure relief cut-out that progressively transitions into a channelled nose increases comfort. Meanwhile, the properly dimensioned nose provides the right level of support and stability, enabling riders to produce maximum power while in forward, aerodynamic positions.

The saddle padding consists of a type-1 formulation—thicker on the nose, where triathletes and time trialists spend most of their time, and slimmer on the ischial bones to provide a firmer feeling when riders need to rise from the aero position.

The Aeris comes with an optional link to integrate a water-bottle cage at the rear of the saddle. The link is designed to hold bottles at an angle that is out of the way during the critical mounting and dismounting phases in transition zones. Complying with UCI rules, the Aeris is equipped with a revolutionary rail insertion that not only provides a more aerodynamic feel but also allows for a broad range of adjustability, necessary to achieve the ideal forward position to beat the wind.

About Fizik

Where the rider meets the bike.

Fizik was founded in Northern Italy with the conviction that the three points of contact between rider and bike — saddle, shoes, handlebar tape — deserve the same engineering focus as the bike itself. Every product is engineered around the rider's body to make the long ride feel shorter.

Fizik's saddle range is organised around the Spine Concept — Bull, Chameleon, Snake — matching saddle shape to rider flexibility. The result is a comfort claim backed by anatomy rather than marketing.
