I have recently bought a road bike having ridden mtb's for some time. use a really basic cateye computer, a MITY 300, which is really just speedo but for the moment it's all I need. The problem is I need t reset it to match the diametre of the wheels of the new bike and tha safe storage space for the book of words that came with it has so fa eluded me. The thing works by entering a code number between 100 an 300 which then corresponds to the wheel size. The new bike runs on 70 - 23 (23 - 622) tyres, if anyone has any ideas I would be grateful Cheers, Be
Checkout www.cateye.com as they have all the manuals for the computers available for download as PDF files.

CatEye computers always used to ask for the *circumference*. If you're using tyres which are *actually* 700x23, then this will be 210cm (pi x diameter = pi[62.2+[2x2.3]]). Tyre sizes are often pretty nominal, though - I'd measure them, which is very simple - just roll the bike along a tape measure laid out on the ground, measuring one wheel revolution from valve to valve, if you see what I mean.
