AeroPod CDA (oleksiy)

Post by TdeCampo »

I use profile 3 most of the time and as John said, the old Aeropod CDA is the choice if time advantage is important.
The problem I have is the following:
Suppose I ride a downhill and I am in drops, so the CdA will go down accordingly, then a climb follows, the speed goes down and the CdA will stay the same (fix) until speed returns. The problem is that the time advantage continue changing so it will be worthless when the flat terrain and speed comes out. The time advantage should not change IF the CdA does not change because low speed.
I wonder if I am doing something wrong?

You aren't doing anything wrong.

What's happening is that your CdA goes down on the downhill while in the drops, as you report. However, at the bottom of the downhill, you start going up, slowing down greatly.

CdA is a difficult quantity to measure below a certain bike speed. When you're traveling slower than the threshold speed our firmware locks-in the last-measured CdA, until speed is subsequently increased above threshold speed.

So, the *low" CdA continues on the uphill, and TA is wrong...

I will see if we can find a workaround for this edge case.

John, thank you very much!.
BTW the correlation of the aeropod and the DFPM is a carbon copy; I used to use the DFPM to re-calibrate the AP/PP now I do not do it any more, both are the same. Great work.

Use the AeroPod 2.0 app, available here:

https://apps.garmin.com/apps/41ca192f-2 ... 496e?tid=1

The original AeroPod app is no longer supported...
