Aira Racing Sport

The Element of Air. Light and free, the Aira road bike moves with avian majesty. A responsive carbon fibre bike with strength, it is as ready to attack the streets of the city as it is to carve turns through the verdant valleys of the English countryside.

Aira Racing Sport

The Aira evokes a competitive edge. It’s got race geometry with a steeper head angle and a shorter wheel base than our endurance models. The result is a carbon road bike with sharper steering and faster response to inputs, ideal for those sprints to the lights, or breaking away from the group when racing. The OSD lightweight road bike frame has a ride quality that is tailored for acceleration and speed, and the Aira dominates whether ascending or descending.
