I stopped using auto calibration because it would sometimes get it wrong, the same ride could be shorter or longer.I've just refitted my GSC 10 unit although awaiting delivery of speed magnet. Once I fit it do I need to change any settings on the 800?
Best to have wheel calibration on auto for eg?
Anything else?
I just the the circumference information printed on the side of the Conti GP4000s/4 Season tyre box.
