Garmin Edge 520 -speed Elite aleno

[jsilva.silva]

Good afternoon I'm finding the speed measure on my garmin with Aleno Smart an very exhausting task, I've being using the calculation - cirunference / 13.2 - giving me the result 158 - the velocity that I'm getting is between 50 and 90KMH.

My wheels are 700-23C, my circumference is 2096. I can get a closer velocity - to the one I can get with Garmin sensor velocity with wheel size 0100, but this is not accurate, this is a number that I've placed by chance.

Can please someone help??

Thanks

Hi

On the Garmin settings, you have to set a circumference equal to the roller one (so, 94mm).
Put this value on your Garmin and speed will be correct.
Please notice that not all the Garmin devices allow to insert a so low value.

I recently set up a direto.
The problem is when I sync my watch to the Direto my speed is a lot higher than what zwift says.
What is the correct we also must you can put on to my Garmin 935 watch?
Will it be the same as the 520?

It may be due to the circumference setting.
You have to insert your circumference value divided by 12.1.
Also consider that Zwift use a virtual speed calculated from power (it doesn't use real speed), so there may be a difference
