Speed sensor: switching 27.5 to 29 inch wheels?

Patkós Csaba

I am about to switch from a bike with 27.5" wheels to one with 29" ones. 

Do I need to do anything special with the speed sensor when I move it to the bigger wheel? Does it have to be reset, or manually recalibrated, or something?

... or I just mount it on the bigger wheel and it automatically recalibrates?

    I will answer my own question.

    The sensor recalibrated automatically. It automatically computer the circumference to 2330 ... or something like that, and that is, according the internet, very close to the 29" wheels with 2.35 tyres.
