Which circumference value do I have to use?

[Rixter]

I got a reply from Elite and they said I should set the circumference to 2100 in the MyTraining app, based on a 700x24 tire

Dear All

i would need some help with the circumference of the wheel entry. I have 700x32c on my bike, which is in mm 2155. But in my elite training app there is mentioned 2070 and it seems that I cannot change this value...

Besides, I was trying to calibrate the trainer, but even after having spinned more than an hour, it doesn't seem to work. It gives no instructions except for 'start peddling' but then nothing happens...

some help would be grateful!
thanks a lot!

Helen.
