Rear Derailleur

1. H Limit Screw

1. Place chain on the largest front gear. Place chain on the smallest rear gear
2. Use rear barrel adjuster and turn CW to loosen the derailleur cable so that the H limit screw establishes H limit as an overly tight rear derailleur cable can prevent the derailleur from seating against the H limit screw.
3. Tighten the H screw until the chain rubs the next higher rear gear
4. Loosen the H screw 1/4 turn until the chain no longer makes noise against the next higher rear gear
5. DONE

Notes:

Barrel adjuster CCW = away from tire. This serves to tighten the derailleur cable and results in the rear gear indexing moving toward the tire. The normal at rest state of the rear derailleur is at the smallest rear gear due to the internal spring. Barrel adjuster CW = toward tire. This serves to loosen the derailleur cable and results in the rear gear indexing moving away from the tire.

2. Rear derailleur indexing

1. Shift 1 gear
2. Turn the barrel adjuster CCW until noise
3. Keep shifting one gear back and fourth until noise stops. Adjust by turning barrel adjuster CW
4. DONE

Notes:

Do not shift to the highest gear, this will be done by setting the L limit screw in the next step. This is to prevent from over shifting past the largest rear gear which causes the chain to fall off into the tire spokes.

3. L limit screw

1. Shift front to second largest gear
2. Tighten the L screw until the chain rubs the largest rear gear
3. Loosen the L screw 1/4 turn until the chain no longer makes noise against the largest rear gear
4. Test by over shifting past largest rear gear. When over shifting is attempted the rear derailleur should not move
5. DONE

4. B screw (body angle screw)

1. Place chain on the smallest gear in front and largest gear in back
2. Use B screw to set the distance from the G pulley to the rear gear to 5-6 mm

Notes:

Tightening B screw increases gap between the rear gear and G pulley, loosening the B screw decreases the gap.

Front Derailleur

1. Set the front derailleur cage height and rotation

1. Front derailleur cage over the largest front gear should be 2 mm
2. Cage should be parallel with the front gears.

2. L limit screw

1. Shift to the smallest front gear. Shift to the largest rear gear
2. Tighten the front derailleur barrel adjuster. This will slacken the front derailleur cable.
3. Tighten the L screw to make the gap between the chain and the front derailleur cage as small as possible (1 mm). This will cause the chain to rum against the cage
4. Loosen the L screw 1/4 turn until there is no more rub
5. Test the L limit. Turn the barrel adjuster CCW ( this will allow the front derailleur to shift to the larger front gear)
6. Use the shifter to drop inward to the smallest front gear. The inward shift should be fast, if not tighten the L limit screw
7. DONE

3. H limit screw

1. Shift to the largest front gear. Shift to the smallest rear gear
2. If the front derailleur won't shift, the cable is too slack. Tighten by turning the barrel adjuster CCW
3. Once on the largest front gear, Loosen the H screw to intentionally making the H limit screw too loose.
4. Put extra pressure on the shifter and hold. Observe the gap between the chain and outer derailleur cage.
5. Tighten the H limit screw and check the gap by pressing and holding the shifter to observe the gap.
6. The objective is to have the smallest gap between the chain and outer cage without rubbing
7. DONE

4. Set Indexing

1. Place chain on the smallest rear gear. Shift to the largest front gear.
2. Find the correct cable setting by intentionally introducing movement at the cage and then systematically removing it.
3. Push on the shift lever, if no movement at the cage, turn the barrel adjuster CW until there is slight movement of the cage.
4. Once there is movement, turn the barrel adjuster CCW, and press on the shift lever until there is no outward movement.
5. DONE
