Definition:
An aero bike is a road bicycle designed with aerodynamic features to minimize air resistance and maximize speed. Its frame, wheels, and components are shaped to reduce drag, making it ideal for racing and fast riding on flat or rolling terrain.
Why it matters:
- Aero bikes allow cyclists to conserve energy by reducing aerodynamic drag, which is the biggest resistance at higher speeds.
- They provide a significant performance advantage in time trials, triathlons, and flat road races.
- Aero bikes influence real-world riding efficiency, helping cyclists maintain higher speeds with less effort.
How it’s measured / used / recognized:
Aero bikes are recognized by their aggressive geometry, integrated handlebars, deep-section wheelsets, and hidden cables. Their effectiveness is often tested in wind tunnels or measured in terms of reduced watts required to maintain certain speeds compared to standard road bikes.
Related terms:
- Time Trial (TT) Bike
- Watts
- Wheelset
Example in practice:
In a flat stage of a road race, a rider on an aero bike may save up to 20–30 watts compared to a standard road bike, allowing them to keep pace in the peloton with less energy expenditure.
