Cycle Trip Computer

[l4dva]

Hi guys,

I have an old trip computer that I need help wth setting up.

Its been sitting in my garage un-used for about 7 ish years now, seems to be working fine. Only problem I have is setting up the correct wheel size for my new bike. I don't have the user manual any more, and a google search of it hasn't come up with anything. From memory I got this from Aldi so im not surprised if can't be found anyways it is a "Boss Cyclocomputer" and has two red buttons "mode" and "st./sp" (start and stop) and thats all it says on the computer itself. When I turn it on I have the option of Kph or Mph and then the next setting is im guessing the wheel size....i can scroll through numbers 100 to 240 this is where I don't know what I would be selecting. These numbers must corespond to the size of my bike, dose any one have any idea of what I should be using, I have 700 size wheels. After selecting one of these numbers it goes straight on to the normal functions screen and is ready to be used so its a straight forward set up in that sence, but I just don't have a clue what setting to select.

If any one has this type of computer or if any techies out there would like to give me a hand it would be much appericated.

Thanks!

The number you want is the circumference of the wheel plus tire in cm's.

Download any manual from here http://www.cateye.com/en/manuals/66
and it will include a table of wheel circs for most wheel / tire sizes.

If you want to be really accurate you can measure yours but it's not worth the hassle.

Only a guess but l4dva says his computer allows him to enter 100 to 240, its in cm ? most computer tables are in mm so they'll need to round/drop the end digit.

Thanks oldlegs! That makes more sence now!

It must be CM that im putting into the computer, 216mm curcumfrence would be a tiny wheel!

Cheers!
