700 x 30 tires

Post by thejr »

Hi Powerpoders!
I notice this is not an option in the bike settings in Isaac or Powerhouse. My tires are 700x30c - what's the recommended value to use instead?

You can give 2136mm under "Measured" in Isaac for this profile.

If you are using a bike computer that can estimate tire circumference from revolutions and distance (from GPS) - like Garmin Edge systems - they can report the value that you can use, too.

Thanks both for the direction and suggestions - yes i think the Garmin speed sensor does this so will check that out.
