Top of the Line, Unrivaled Sophistication

While wind-tunnel measurements of aerodynamic drag coefficients (CdA) are accessible to some cyclists, they are still way out of reach for the rest of us.  The iAero provides an unrivaled tool that not only measures power but delivers aerodynamic drag coefficient measurements that have never before been available in a cycling computer.

Take Your Competitiveness to the Next Level

No more second guessing what might give you the winning edge, the iAero provides measures that lead to the same improvements normally limited to a visit to a wind tunnel.

The Must-Have Tool for Competitive Cyclists

Right on your screen and in downloadable format iAero gives you the ability to:

• improve your ride position;

• test the aerodynamic impact of your cycling equipment; and

• find the optimal combination of aerodynamics and power.

Equipment and Position Evaluation:

Snapshot Drag Coefficient

Want to determine your best riding position to beat the wind, or test the aerodynamic impact of changing your equipment?
iAero displays a point-in-time aerodynamic drag coefficient (CdA) on your screen whenever you coast.  The lower the CdA number, the more streamlined you are.  Try out different riding positions, change helmets or other gear and let iAero quantify the aerodynamic benefits.

Optimal Combination of Aerodynamics and Power:

Continuous Drag Coefficient**

Looking to establish your optimal combination of aerodynamic positioning, equipment and power? 

Want to know instantly if you're deviating from your optimum ride position?

iAero displays instant, continuous aerodynamic drag coefficient feedback on your screen even while pedaling!  When you ride with both the iAero and an additional ANT+Sport^TM direct-force power sensor, your iAero provides information that enables you to find your optimal combination of aerodynamics and power.  You'll know instantly if you're deviating from your optimum aerodynamic riding position.

A New Way to Win:

Time Advantage^TM**

How much time do you pick up when you go into a tuck?

How much time does it cost you when you sit up to drink water?

These are just some of the many questions the exclusive Time Advantage^TM feature answers. You can't answer these questions in a wind-tunnel but you can answer them with Time Advantage!  iAero measures (in seconds) the cumulative amount of time you've gained (or lost) due to changes in ride position or equipment during your solo ride and reports it in real-time on your screen.  When you ride with both the iAero and an additional ANT+Sport direct-force power sensor, you can see the time impact of your changes on both your aerodynamics and power.  Now you can make real-time adjustments and realize real time advantage during your ride.

Powerful New iBike3 Software Features
Using either a wireless ANT^TM + Sport or traditional power meter in combination with the iAero unlocks new and exclusive features in the iBike3 software. Now riders will be able to relive their ride through Continuous CdA and Time Advantage data. This amazing information provides a new and exclusive way to improve training regimens and overall competitiveness. Download your free copy of the iBike3 ride analysis software!
