    Bike Computer

    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.

    Who is this General Failure anyway, and why is he reading my drive?

    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?
