Hi all,

I was just wondering, on my Spark 3 watch, you can input the wheel size for your bike.

However, does this refer to the wheel size (eg 26 inch wheel) or the width of the wheel/tyre (eg 25mm) ?

Many thanks,
Tom

    The circumference so it can calculate distance (it counts the number of rotations and multiplies that by the wheel circumference). The width is irrelevant. I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
