I have a sigma speedmaster 7000 model and cannot remeber how to set the
wheel size (lost the leaflet that came with it) I have a choice of 3 wheel
sizes (which I assume if the first number as it goes from 1 to 3) then a
three figure number ( I am using miles rather than km). Would
the 3 figure number be 27.2in or 700cm

did you look at

Live simply so that others may simply live

Yes thanks Neil. I could not find my Model there. The problem is the four
figure number and what to enter. The first digit reads 1 -3, and the other 3
read 1- 10. I assumed the first number was there for for different wheels
or km/miles. That leaves me with a 3 figure entry. I remember it being very
simple whe I did it 3 years ago!!

Does "the circumference of the wheel in millimeters" ring any bells?

Alex is right. It should follow this particular page, +/-

I'll give that a try, but why should that first number allow you to enter a
2 and a 3 (penny farthing wheel) 🙂

Because the nominal circumference of a 25-622 tyre is well in excess of
two metres. The '3' is unlikely to see much use and a decent-sized
penny-farthing would need a '4'.

Tip for penny riders, divide the circumference of the wheel by 2 and fit
two magnets diametrically opposed.
