Powerpod on mtb equipped for bicycle touring

Post by doib »

Hello John,
I'm about to leave for a cycling tour in Trentino and I would like to bring the powerpod (if I can find a space for mounting it on the handlebar ..). I have prepared a drawing, which I am attaching, to evaluate my front surface with the bags, tracing a photo of a past trip. How can I use the numbers obtained, provided they are sufficient to create a profile with realistic power values? Furthermore, I noticed that my front surface without bags is quite superior to the CDA set automatically by isaac for the other mtb, but it is quite close to the Aero value (I attach screenshot), except for the inevitable inaccuracies in the design and perhaps in the scaling of the photo. Do I have to update the profile or are the values correct like this?
Thank you, bye.

Davide

I would use a CdA value of 0.554. This is the total frontal area of you and your bags; I doubt there is much of a Cd benefit from panniers!
