FAQ

Notio must be configured using an iOS device with the Notio application. The iOS device communicates with the Notio using Bluetooth while the Notio communicates with the sensors (power meter, speed and other compatible sensors) using ANT+.

The iOS device is used to configure and transfer Notio data using the Notion application. It does display the CdA in real time and does allow data analysis without login in Golden Cheetah.

The Notio app allows you to : 

• Create a Notio Cloud account ;
• View the recording status of the Notio ;
• Configure the Notio 
• Synchronize ANT+ sensors ;
• View real-time values of the Notio sensors ;
• Access the memory of the Notio to transfer data ;
• Update the Notio Firmware ;
• View the percentage of the battery charge ;
• Benchmark and analyze your aero performances through time ;
• Track your activities and their related statistics ;

Notio calculates :

CdA (aerodynamic drag coefficient), relative altitude, air density, wind speed, acceleration, roll, vibration.

Yes. 

No.

The Notio app can display CdA values in real time. Garmin was selected among others because this company offers the widest selection of GPS cyclometers on the market.

BIKE PROFILE SETUP

Unit of measure : select Metric or Imperial

Total weight (kg) : ** value must combine your weight (w/ equipment) + your bike **

Tire circumference * : see the common tire circumference chart

Rolling Resistance (CRR) ** : default value should be 0.004

Calibration Factor *** : default value should be 1.39

Time window **** : default value should be 60 seconds

* There are many reference tables from cyclometer manufacturers, including Garmin and Cateye, to assess the circumference of tires based on their dimension. As a rule, for a 23 mm wide tire the circumference will be 2096 mm; for a tire 25 mm wide it will be 2105 mm.

** The Rolling resistance (CRR) coefficient is caused by the elastic deformation of the tires and the rolling surface. The default value in the Notio app is 0.004. This value corresponds to the rolling resistance of the most popular good quality tires on the market. To explore the subject or to check a specific tire model, click here. 

*** Calibration factor : formerly named «Coefficient 1», the calibration factor is the result of the CdA which corresponds to the wind impact on the cyclist.

**** Time window : time Window is the time duration in seconds used to calculate the average value of the CdA. This duration is displayed on a compatible Garmin device in the Aerofields field. The default value is 60 seconds, which is a reasonable time for a stable position. / A parallel can be drawn with the power display. In order to prevent the value from changing too much it is common to display the average power over 3 seconds on the cyclometer instead of the instantaneous power. A user will usually display the 3 sec or 10 sec average power, which smooths data. The same goes with the CdA. As more variables are used to calculate the CdA, a bigger average time window will generate a more representative figure.

The main reason for using a speed sensor, rather than GPS speed, is that there is a slight lag between speed acquisition through a GPS and power recording with the power sensor. This lag is significant enough to distort CdA values. Also, the accuracy of the speed may vary depending on the GPS device, the chosen mode, and the obstacles. This variation will also distort CdA values.

The parameters entered in the BIKE PROFILE SET UP are transmitted to the Garmin. It's important to have the right settings in the configuration to get a good real-time CdA value on your Garmin. 

Notio is compatible with brackets that have a GoPro-style interface and it comes with 2 brackets: one for road bike handlebars and one for the time trial/triathlon bars. 

Road bike | The mount for the road bike must be centered; the wheel can be used as a guide. 

TT Bike | The mount for the time trial bars must be positioned as far forward as possible on the bar.

To take maximum advantage of the Notio, device must be installed as far as possible in front of the bike. from the cockpit, centered on the front wheel, Pitot tube parallel to the ground.

In order to determine the Calibration factor or to evaluate the CdA according to a more detailed option (e.g., a new position on the bike or new piece of equipment), the following protocol is recommended:

●      Choose a safe place for the test ride. Security must be prioritized

●      The ideal terrain is a slight semi-flat. Avoid steep inclines

●      Make at least one round trip of 6 km (3km out / 3km back)

●      You must keep the same position on the way out and the way back

When the activity is imported into Golden Cheetah Notio, the round trip is analyzed in the Notio CdA Analysis chart. The goal is to balance the amount of wind on the go compared to the return, while taking into account the travel speed. The figure obtained in Factor corresponds to the Calibration factor.

NOTE : A simple way to ensure the good Calibration factor is to do the protocol described above once at each use of the Notio. If Calibration factor remains substantially the same each time, confidence in this value will be high. If it turns out different at each analysis, it may be worthwhile to do more than one round trip so to increase confidence.

If you have any trouble to complete your CdA benchmark ride, please contact our support team : support@notiotechnologies.com

No.

Once the first CdA Benchmark calibration is done, it is not necessary to calibrate the unit before each ride. Calibration becomes necessary only when the position of the Notio device changes.

Ex.: mount position, cockpit adjustment, fitting modification, etc. 

If there is no changes, calibration is not required before each use in order to find the Calibration factor. 

NOTE : whenever a (new) position or equipment is tested, it is recommended to do at least one round trip. This can also be done to check the calibration.

Coefficient 1 is used as a calibration factor in the calculation of the CdA in relation to the wind impact on the cyclist. The way in which the wind comes in contact with each cyclist is different and will vary namely according to the cyclist (size, weight) and the position of the Notio on the bike (position on the bar/handlebar, height relative to the wheel). Once the Coefficient 1 is found, no need to modify it unless the Notio or the cockpit changes position.In the case of an erroneous Coefficient 1 when recording with the Notio, the right CdA values will be determined in Golden Cheetah Notio with the analysis tools. If Coefficient 1 is incorrect, the values displayed in real time on the Garmin device will also be incorrect.

Go to the Notio App and follow the instructions to set a benchmark CDA value. This will set the coefficient 1 value for you.

The CRR is the rolling resistance coefficient. It is caused by the elastic deformation of the tires and the rolling surface.The default value in the Notio app is 0.004. This value corresponds to the rolling resistance of the most popular good quality tires on the market. To explore the subject or to check a specific tire model, click HERE.

Data is saved on the Notio until it gets transferred. Notio-specific data is not saved on the Garmin or iOS devices. Once an activity is completed, it can be transferred from your Notio to the Notio Cloud, using the Notio iOS application.

Golden Cheetah allows more customization and analysis than Garmin Connect.The Golden Cheetah Notio version is mandatory in order to be able to analyze all that's related to the CdA and other data recorded by the Notio, as this data will not be available in the Golden Cheetah standard version, nor Garmin Connect.

1. Synchronize Golden Cheetah Notio with the Notio Cloud.

Open Notio app / Select Activity / Notio Files / Click on the ride of your choice. 

Congrats! Your ride is now in the Cloud.

2. Add Account in Golden Cheetah Notio

Open GCNotio / Share / Add Cloud account / Activities / Notio / Authorize / Next until Finish button

Import manually into Golden Cheetah Notio

3. Open GCNotio / Share / Synchronize Activities / Notio / Select rides to download

Make sure to display the CdA in the Golden Cheetah Notio interval options :

MAC user

GCNotio / Preferences / Metrics / Intervals / Notio Metrics

Windows user

Tools / Options / Metrics / Intervals / Notio Metrics

Ask Golden Cheetah Notio to do the math by going to Tools / Notio / Compute. 

Use the Notio CdA Analysis chart to check the settings and calculate calibration factor for selected laps (Calibration ride is composed of 2 laps).

Only as an indication since several factors can affect this data:

Professional Cyclist and position CdA Power *

Tops 0.408 377

Hoods 0.324 314

Drops 0.307 300

TT w/ road helmet 0.243 248

TT w/ aero helmet 0.232 239

* Total weight 75kg at 40 km/h on a flat course

By using the Notio CdA Analysis chart in Golden Cheetah Notio. 

You have to remember that Notio is a TOOL. Data analysis thus largely depends on data quality. To get quality data, you must correctly configure the Notio, use a high quality power sensor and make good round trips for the Calibration factor and for testing. 

To increase confidence in data, increase the number of round trips.

As a rule, frequent changes of position, shocks (potholes) and abrupt acceleration or deceleration distort the CdA. Wind gusts, whether natural or caused by vehicles, also affect the CdA.

The Notio is an electrical device that transmits and receives signals; therefore it can be sensitive to electromagnetic phenomena. Short signal losses may occasionally occur. However, repetitive signal losses of more than 5 seconds are atypical.

For the CdA, the precision of the Notio is estimated at three decimal places 0,000. 

To achieve this degree of accuracy, users must obviously enter their correct weight and wheel circumference (Notio app / BIKE PROFILE SETUP / Total weight (kg)). 

Quality power sensor

The power being the most important factor in all calculations. Obviously, figures obtained in a wind tunnel will be more precise. However, the Notio advantage is to be able to test in real conditions. 

Also, users can do as many tests and round trips as they want, according to the time they have, in order to increase confidence in the data obtained with Notio.

Notio can record a lot of useful data without a power meter. However, in order to get your CdA, you will need one.

Be aware that some power meters have stronger signal than others. Furthermore, a power meter that is more precise will generate a more precise CdA. 

Double-sided power meters are strongly recommended.

All these sensors can be used with the Notio : electronic shifters, cadence, speed cadence, speed, heart rate monitor, power meter. 

NOTE : sensors must be ANT+.

No. 

However, you can control the Notio with your phone to start and stop recording data. Also, you can use the button directly on the Notio device.

Notio currently supports iOS 11 and higher. An Android version will eventually be issued. For updates, please contact us by email support@notio.ai  

The Notio uses ANT+ to connect to sensors. 

The Notio talks to the iPhone with Bluetooth Low Energy (BLE).

If you used the old App and try to pair your sensors in the new App, it will not work.

You have to reset all the sensors ID in the old App before.

Follow the new UPDATE PROCEDURE. 

It allows you to analyze the efficiency of an object irrespective of its size or velocity.

In fluid dynamics, the drag coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. The drag coefficient is always associated with a particular surface area.

With our Golden Cheetah Notio app. We develop preset tabs that display data. 

If you have questions, please contact our support team (support@notio.ai).

The CdA calculation is based on your speed and the frontal air speed. If you don't change your position on the bike, then your CdA should not change. 

Let's look at a basic example :

Think of a car rolling on a straight flat highway in a stable weather except for the wind direction that may change. The car always goes at 100 km/h. This car has a given CdA of 0.002.

First case, there is no wind. The car has a fuel consumption of 5 L/100 km and its CdA remains 0.002 since the shape doesn't change.

Second case, there is a strong head wind. The fuel consumption increases to 8 L/100 km. The CdA? It remains 0.002.

Third case, there is a tailwind. The fuel consumption drops to 3 L/100 km. 

You would guess the CdA is still 0.002.What do we learn from this? We learn that in similar conditions the wind's direction will only affect the work needed to maintain a given speed. 

Bottom line, the CdA is independent from wind direction.

You can synchronize your Golden Cheetah Notio with several training platforms such as Strava or Training Peaks. However, only your regular data will be displayed, not the Notio specific data.

No. 

You get a display on your Garmin and in the app only if your iPhone is within the BLE range.

The biggest current advantage is to get live CdA without having to go to the wind tunnel or a velodrome. You get a CdA in real life conditions. But this is only the beginning. With six families of sensors you can collect maximum data to perform maximal analysis. Think about Notio as a black box for bicycles.

Using Garmin IQ, the information is displayed as a data field on one of the data screens in your activity profile. The display shows the CdA, wind speed and the ANT+ sensors status.

Yes.

You will get better results with TT and triathlon. But the Notio has not been UCI approved yet.

The Notio App has some summary data to look at post ride so you can make equipment choices in the field. If you wish to analyze your ride data in more detail we have a Golden Cheetah Notio version which has preset tabs that display data. You can download Golden Cheetah Notio version once you purchase a product.

0.000

Yes, upon installing it on the mount. You also need to do a calibration each time you change the position of the mount and switch the device to another bike.

The CdA could be calculated to the second, but it is better to choose a bigger average time window. We suggest around 60 seconds. Consider your power meter data with all its spikes and variability. A user will usually display the 3 sec or 10 sec average power, which smooths data. The same goes with the CdA. As more variables are used to calculate the CdA, a bigger average time window will generate a more representative figure.
