I know it seems a silly question, but looking around 'tinterweb it's not that easy.
Really the question is "what wheel diameter should I program into the controller of my new GSM kit"?
The manual for the 800S LCD says that I can choose between 16/18/20/22/24/26/700C/28/29, although the beast itself offers 27 instead of 700C.
On the other hand if I look up the tyre size (40-622) on the Schwalbe website it says that my wheel diameter is 2220mm, which equates to a diameter of 27.82 inches - so the nearest would be 28, and indeed Schwalbe classify it as a 28 inch tyre.
So - is the 800S set up to use nominal or actual wheel diameter?
