Review components that make up the shifting system, which allows your bike to shift smoothly through gears
-
Handlebar Shifter Inspection:
- Examine the shifter on the handlebars for any visible damage, bumps, or dings.
- Ensure that the shifter is in good condition.
-
Shift Sensor Check:
- Follow the cable from the shifter to the shift sensor (if included on your bike) and inspect it for damage.
- Verify that the shift sensor is not smashed or damaged, as it plays a crucial role in stopping the motor during gear shifts.
-
Cable Inspection:
- Examine the cable for any visible damage as it travels down to the frame.
- Inspect the cable where it enters the frame, even though the internal components cannot be seen.
-
Rear Derailleur and Cassette Inspection:
- Check the rear derailleur for damage, rocks, bends, or kinks that may affect its performance.
- Gently move the cassette to inspect for any visible damage, cracks, or broken cogs.
-
Chain Examination:
- Inspect the chain for any signs of damage, bends, or kinks.
- Examine the front chainring, especially the teeth, for any bending, damage, or breakage.
-
Tuning the Derailleur:
- Once all components are visually inspected, proceed to tune the derailleur to ensure proper functionality.
- Refer to the Derailleur Adjustment or Limit Screw Adjustment instructions for direction on tuning your derailleur.
