, hereinafter referred to as provider, the following contract.


This agreement governs the sale of aerodynamic measurement, analysis and optimization services to cyclists through the provider’s online platform, aeroDATA. Regarding the details of the offer and the services for the respective forms of the subscription, reference is made to the product description of the offer page.

(1) The terms and conditions are based on the following definitions:

a. aeroDATA

The aeroDATA combines all other services of Aerotune – aeroTEST, aeroCAST, aeroREV etc. – on a web platform and is used by a freemium, premium monthly or premium annual account of the customer.

b. aeroTEST and aeroCAST

The “aeroTEST” determines the CdA value from the uploaded data and gives a predicted bike split time (aeroCAST).

c. CdA value (wind resistance)

The CdA value means the effective frontal area in the respective position of the cyclist with the material used in relation to the selected distance.

The calculated CdA value is based solely on the data transmitted by the customer. In spite of the use of the most recent algorithms, it represents only an approximation to the actual CdA value. The accuracy of the determined value depends, among other things, on the selected route, the wind conditions, the strength of the GPS signal and the technically correct acquisition of the power meter of the third party.

d. Bike Split

The predicted bike split is a guideline calculated using current algorithms. This is based on a constant wattage and compliance with the underlying cycling equipment and seating position. Actually, occurring deviations of these recorded parameters lead on the respective competition routes to corresponding deviations of the respective bike split.

e. Test Methods

The test is possible in two different scenarios

  1. “aeroREVERSE”: The customer can completely record the data of a particular competition and make it available to the provider. Based on this data, the provider calculates a prediction of the forecast time for other routes (forecast).
  2. Test Track: The customer rides 1 kilometer with a constant power on a selected test track and then returns immediately afterwards. The provider determines the CdA value and predicts a bike split time for the existing in the record of the provider competition routes. Detailed test instructions for the best possible performance of the measurement can be found on the website of the provider. The customer can ride the respective test track with different equipment and draw conclusions about suitable material on the basis of the calculation of the CdA value and predicted bike splits.

f. Records

In order to carry out both scenarios of the “aeroTEST”, it is necessary to transfer special data records by the customer to the provider, which is done automatically by the customer on the aeroDATA platform, the data being collected by a power meter with a third-party GPS system Data acquisition via GPS system and power meter is to be ensured by the customer during the measurement.

  • Content of the records

The data records sent by the customer contain all data necessary to calculate the CdA value and the forecasted times.

  • Format of the records

The data records are to be transmitted by the customer as a “fit” file to the provider.

All analyzes are automatically created on the platform and displayed to the customer in their profile.

Transmission shall mean the transmission of the records using only electronic means of distance communication. The transmission takes place by means of uploading the data records by the customer to the provider.

  • Data protection / processing of the data

The privacy policy of the provider is available here.

g. Power Meter / GPS signal

A power meter enables you to record the power in the selected seat position with the respective wheel equipment. The distance cycled, and the speed are determined using the GPS signal.

h. System weight

In addition to the recorded data of the power meter and the GPS signal, the system weight must be communicated to the Aero test. The system weight is the combined weight of the equipment used and the weight of the customer in kilograms.
