Help and advice please. Despite inputting wheel size and checking many times my Sigma BC600 is way over estimating distance and speed. I measured the distance from valve stem for 1 revolution at 2085mm and checked it. Only today I went on a short road ride that I know is 7 miles but the read out was 10.91!!. Anyone got any ideas? It just doesn't make sense. Thank you.
