When i first got mine it prompted me to enter the circumference of my tire in millimeters (mine was 2074mm). you can get back to this by holding the bottom button in the center (this button is really two buttons one on the left side the other on the right side; holding the center pushes both these buttons). when it rests you'll see the 4 digit numbers. i think u use the right button to change the number and the left to move to the next. remember the number represents your tires circumference in millimeters. for a quick approx use this calculation (Tire Diameter)X(3.14)X(25.4). So for me it was (26in)X(3.14)X(25.4) = 2074mm

### Have an older Huffy female 12-spd road bike that is missing the rear wheel assembly. Looking to find a replacement as well as instruction manual...wheel assy. more important. Thanks.

Unless you have a deep sentimental connection with the bike, it may not be with it:
Rear wheel - \$35-\$45
Rim strip/tape - \$1
Tube - \$8-14
Tire - \$10-20
Gear cluster - \$25-40

You might be able to find a used bike or wheel at a garage sale that would work.

### Lost my manual and am trying to reset my bell f20.

Somewhere in the configuration program is the option; if you can't find it it in the instructions, that's probably because it doesn't have this option, in which case, you should try and trade the bike comp. off for an American-built one. (guaranteed to have MPH)
