What this video covers
Adjusting the derailleur when the bike isn't shifting properly (Shimano Altus 7-speed).
Steps
- Flip the bike upside down and rest the bars on stands to protect the display and shifter.
- If the derailleur guard is bent inward (common from shipping) and blocking a gear, bend it back into place.
- Set the high-limit screw so the derailleur can't travel past the smallest cog.
- Set the low-limit screw so it can't travel past the largest cog into the motor.
- Shift to 3rd gear and use the barrel adjuster to index the derailleur directly over that cog.
- Test-shift through all seven gears, up and down.
