Simplest thing is to just crack open the speedo cover and put your own markers on it. There really isn't any way to adjust the calibration of the speedometer easily. Many people just buy and install a bicycle cyclocomputer and be done with it.

That's what I did when my speedo cable broke. Works great.

Effectively doing this: www.canyonchasers.net/shop/generic/sigma.php

Here's some text copied from a previous post I made:
I use a Sigma 509 Bicycle Speedometer. ~$15 off Amazon. Once calibrated, works great and accurate. I don't think I have too many details on how I installed it, but if you have any questions, I can try to help.

Basic steps (I think I make it sound more complicated than it really was):
-Epoxy a rare earth magnet from Radio Shack to edge of rim.
-Mount Sensor to fork. (I had to fab a small bracket to get the sensor close enough to the magnet.)
-Lengthen sensor wire to reach handlebars.
-Mount computer to handlebars as intended, or velcro to panel.





Sigma Computers are the best. You can find alot of information on the web about people using them on motorcycles. The cheapo Schwinn's/Bell's/etc.. from Walmart are crap. They'll get to about 45mph then die. You've also got to use the wired models as wireless ones can't keep up.

One of these days I am going to open mine up and put my own numbers on it. From what I have seen the speedo's are off in a non linear fashion. As I recall mine is right on till about 35 or 40 then it goes off. In electronic stores you used to be able to buy rub on transfers in many sizes for letters and numbers. as long as your china speedo repeats the error, remarking it is just fine. john

There are sites online where you can design your own etched acrylic with whatever design you want, so basically you can make your own backlit speedo face. Just need to upload an eps file for the design. It's actually pretty cheap, maybe $20-$30 for a 1' square custom design, and the acrylic can be of various colors.
