cyclocomputer mess

tell me if calculating it as a 3 rule knowing the mileage marked, the size marked and the actual
size will actually give me a credible result. thanks.

Yes, it will:

Actual distance = marked distance * actual size / size marked

got to change my cyclocomputer battery and forgot to set tire size, now my mileage is all screwed
up, not that i use it much but this was the year i planned to get an actual log of my mileage, i
could restart from zero but when you ride as much as i do every little mile is a whole lot of
encouragement and don't want to end up thinking that i rode 100 = miles in the year, it would be
better know that i rode all 105,74 miles in 2003. So i just want to know if some of you the not
mathematically challenged

can

I think you are asking how to set the wheel travel setting, right? Most computers accept the wheel
travel in meters. Best method is to ride over a spot of paint and measure from dot to dot on the
pavement ( or even over several dots) A typical entry is "211" or "2105".

This is typical but by no means universal. What kind of computer do you have?

If you are asking how to input your prior accumulated mileage, I don't know.

I want wheels that big.

I think you are asking how to convert the indicated mileage with the wrong tire size to actual
mileage. This is fairly simple. Simply divide the actual tire size by the size stored in your
computer and multiply this by the indicated mileage. This will give you the true mileage.

For example, if the stored value is 210 (cm) and the actual circumference of your wheel is 205 (cm),
you would divide 205 by 210 (.9762) and multiply this by the mileage stored in you bike computer.

Hope this helps.

Many cyclocomputers will allow you to have wheels that big. See:

And I was trying to point out that many cyclocomputers accept wheel circumferences in centimeters
(e.g. 211), while many others accept circumferences in millimeters (e.g. 2105).
