Hello

I have to set the wheel size at the Polar 720i, the size is 26x2.1 but it asks for a 4 digit number... any one knows which is?

Thanks in advance

It wants the rolling circumference of the wheel in millimetres. (25.4mm = 1 in)

For what it's worth I have my MTB set up at 2030mm, and I normally run 26x2.0 tyres on it. From memory the manual (available from the Polar web site if you don't have a hardcopy) has a couple of suggested numbers if you don't want to measure it yourself.
