Hi, I wonder if anyone can help me out. I just started cycling again after a long break. I have a new bike and a new cycle computer.

I did my first half decent ride of 25 miles which totally knackered me as 20% of the ride is steep hills.

Upon inspection of my cyclometer I realised that I had used the wrong wheel size setting. I had setting number 2 active which was 82.6 when I should have used setting number 1, 84.8.

Can anyone recalculate my distance of 25 miles for me converting it from 82.6 wheel size to 84.3.

I reckon I must have ridden farther than I wanted to which is probably why my knees are totally shot.

Any help would be appreciated. Thanks.

Never heard of a wheel size in the 80s range... Your bike computer manual should list the corresponding wheel diameters, or tyre markings. Those would help.

Hi, It's the lenght of 1 roll of a wheel in inches that you enter into the cycle computer.

Is it just a case of dividing the 25 miles by the incorrect setting of 82.6 and multiplying it by the correct setting of 84.8?
