How do I re-program the number of teeth into my 6502? I went from a 52-39 Sora to a 53-39 Ultegra SL and need to change that value. Do I have to all-clear and re-program EVERYTHING? ugh. I also like my max speed on there.

Look on the Shimano website, there will be a manual for your computer.

Reprogramming everythign is not that big a deal, it will take you less than 5 minutes. Just note the mileage beforehand if you want to program that to start at the same number again.

It will seem complicated when you look at the directions, but once you get to programming the computer, it is easier. It might also be helpful to write down your cassette gears before you start so you don't have to look them up while programming it.

Take it off and wipe your contacts on the cradle and base of computer
Yea and use some electronic contact cleaner (available a lot of places like hardware stores, radio shack etc.). Spray the heck out of it w/ the spray and wipe it aggressively w/ a cloth.

Be careful with electonic cleaners some can damage plastic maybe some isopropanol alcohol.
