Front Derailler Adjustment

Note: The front derailler should be adjusted only after the rear derailler.

Look closely to find which limit screw does what since their positions vary on different models of front deraillers.

1. Make sure the front derailler cage is parallel to and above the largest front sprocket by only about three millimeters (1/8 inch).

2. With the rear derailler in high (smallest sprocket), tighten the front derailler high gear screw until you cannot shift into high gear (large front sprocket). Back out the screw while turning the pedals and operating the shifter until you just get a clean shift every time.

3. Repeat this procedure for shifting down to the smallest front sprocket, but with the rear derailler engaged in low gear.

4. Check all combinations of front and rear gear selection. You may have to compromise the adjustments a little to get a clean shift in all cases.

5. Because the chainwheels (front sprockets) are probably not perfectly flat, try all combinations of shifting when the pedals are at varying angles of rotation.
