bike computer question

[mtbdarby]

So, with the new year and looking to blast my old mileage record, how do I reset my odometers on my bike computers? Do I have to take out the batteries and reset it or is there an easier way?

[SadieKate]

Every computer is different. The manufacturers are generally pretty good about keeping instruction manuals on their web sites.

If you log at bikejournal.com, the site will track both lifetime and annual mileage for each bike without needing to reset your cyclo-computer.

I just updated my bj info - I didn't use it at all in 2006 (sorry!). So I'll need to add up all 3 computers to see what I did last year. That's why I thought it would be easier to reset them all - all 3 different computers. Then I'd know what I did at a glance versus having to be at a computer to know my miles. Thanks, though. Guess I need to look it up.

On many models you have to press two buttons at the same time for a few seconds...

Be aware that you'll have to re-enter your wheel circumference...

[SadieKate]

On my computers that resets the trip distance but not the total odometer distance.

Taking out the batteries on any computer probably resets the wheel circumference to zero.

hmmmm ... If you underestimate the wheel circumference, would that make you appear to be going faster than you really are?



yes I'm that desperate

Quoth jobob: "hmmmm ... If you underestimate the wheel circumference, would that make you appear to be going faster than you really are? yes I'm that desperate"

Ummm, is there a solution there for me too? ... nope. darn. But since distance is number of rotations times wheel circumfr., a circumfr. of 0 would give you a distance of .... zero. Too bad. That won't get me to my goal either. And anyway, I use a gps.

I think if you set the wheel circum. at smaller than your actual circumf. is, it would make you appear to be going slower than you really are, and it would also make you appear to have travelled fewer miles than you really had.

So 700 c wheels really are faster than 650B or 26"!

Nice logics there, V.

Jo, if you want to get really exact calibrating your compooter, Sheldon Brown has rollout instructions or just a way to use a measured course to find the correct calibration number.

Using a measured course to fine-tune your setting
If you have access to a measured course, you can fine tune your settings by riding the known distance and checking the reading. Divide the actual distance by the cyclometer's mileage reading, then multiply your calibration number by the result to get a corrected calibration number.

(Actual Distance / Cyclometer distance reading) X Old Calibration Number = New Calibration Number

I'm too lazy to do this.

Only if you have 700 wheels and set your computer to 650 wheels!

As Barbie would say, Math is Hard.

Me too!

It's too bad they don't make a 1000 c wheel. We'd really fly then. Of course helium or better yet, hydrogen, in your tires will make you go faster.

I wonder if 29'ers are fasting than 700s.

If you inhale helium it may appear to you that you are going faster.
