Set 29er Wheel Circumference with Powerhouse App

[tonywilson]

New user here. Working great on my MTB so far! Question though...

I am on a 29er and set up using the iOS app. I selected the 29er option and chose the largest tire circumference I could see of 700x38 which, from memory was 2180mm. However, I am running 29x2.3 tires which come in at 2326mm - so about 6% discrepancy. Will this make a difference to the power reading and if so, can I change it in iOS or do I have to download and install Isaac?

Thank in advance.

Your power readings will be about 6% low with the current settings.

There is no manual way to use the PH app to set wheel circumference to your value.

If you want to "get things right" you will have to install Isaac and reset things there.

We will make a note of your issue for the next release of PowerHouse Bike app.
