Does anyone have one of these fitted and FULLY understand it?
I just fitted a GSC10 to my XC bike, but I'm confused about the speed sensor.
On one hand it says that it's all self calibrating because of the edge 800 GPS doing the speed... Does this mean I don't need to worry about entering wheel sizes in the bike profiles pages (as this has switch to automatic)
Do I literally have to do nothing other than make sure the edge 800 recognises the GSC10?
Ultimately I don't want to get to the end of a 40mile ride for the data to say it was a 20miles ride and my average speed was 14mph.
Any help much appreciated.
