wrong speed data

I have an Aleno smart trainer which is connected to my android phone through bluetooth where i'm using the myetrainer app.
But I also have a Trek speed and cadence sensor connected to my bike computer.
During trainings my speed measured by the trainer is typically 4-5% slower than the speed measured by my computer. My computer is configured with the exact circumference of my tires. Is it possible that the trainer speed sensor is off, or it must be my computer showing the wrong data?

On your bike Trek, you have to modify the circumference value.
When the wheel is pressed on the roller, its dimension decreases (the roller goes to the inside of the wheel).
Check how much it goes to the inside and calculate the new circumference to set.

Hello

For my aleno using Garmin forrunner 645 the value is 184 km/h when actually rolling at maybe 10-11 km/h. It can't be the circumstances

Can you fix this for me ?

If you use Aleno, you have to set on the Garmin a circumference equal to the circumference of the elastogel roller.
So, you have to set a circumference of 94mm.

Please notice that not all the Garmin devices allow to insert a so low value.
