measurements, anybody know?

[calco]

Got a little speedo/distance thingy and it need my tyre size in mm, tried measuring but nothing seem to completely match the options. On my tyre in says "26 x 2.0" now would anybody know what that is in mm?
If you need any other info just ask
thanks, Calco

The computer needs to know how far the bike has travelled for each revolution of the wheel so you need to put a blob of paint or toothpaste or mustard or something on the tyre, roll it along until it has made two marks on the floor, then measure the distance between them and programme that into the computer.

You could just use the standard size that'll be in your computer manual, if you don't have it will probably be online.

Or if you want to be more accurate you could measure the circumference.
I find it easiest to start on flat surface with the tube valve at the lowest point, mark and push the bike forward until the tube valve goes full circle, mark again and then measure the distance between the 2 marks. Although not neccesary I usually do this a few times.

Just brought a Cateye Strada cadence computer for mine and according to their conversion table which came with the instruction manual 26x2.0= 2055mm.
Hope this helps.

Just enter 2055mm unless you want to be more accurate.
