Just testing new cycle computer again today.
Circumference measured 2080mm.
Looking at the chart that's for > 700x19C.
Popped out for quick test and computer says 4.3miles and GPS said 4.4miles.
On chart doesn't have 26x1.9 closest was 26x1.95 and that was 2050mm, when tested that it was 0.3miles out.
That was yesterday but went further, so more miles you do the more it goes out by, obviously.
So by using circumference measurement it's 0.1 miles out....wondering how much to change the 2080mm by.
Sorry if any of that is totally confusing
