This video will teach you how to adjust your derailleur if your gears are slipping or sticking.
This is a simple fix which can also be useful on the roadside, for example after a fall which has bent the derailleur out of place.
To adjust the alignment of the rear derailleur cage, you will need a cross-head screwdriver.
This video will focus on the rear derailleur since it the one which usually needs the most adjusting
The key steps are: checking the alignment of the derailleur over the rear sprockets, adjusting the gear cable tension, checking the gear.
If, when you try to move up a gear, the chain falls or slips back down.
You need to add tension to the gear cable.
This can be done by turing the barrel adjuster, normally found at the gear shifter, anti-clockwise.
Start in the smallest rear sprocket.
Rotate the adjuster a half-turn and try changing gears once more.
Repeat this step until the gear changes quickly and smoothly without slipping.
You can also check the tension of the gear cable.
- as a rule of thumb, you shouldn't be able to pull it more than 1-2cm away from the bike frame
Crouch behind the bike.
Look to see if the rear derailleur lies directly below the smallest gear.
If the derailleur cage is out of line with the sprocket, or if the chain consistently falls off the rear chainrings altogether,you can make small adjustments by turning the derailleur limiter screws.
These are normally marked H, for high, or the smallest sprocket, and L, for low - or the largest sprocket.
The H screw limits how far the derailleur can move away from the wheel hub.
While the L screw limits how far the derailleur can move towards the wheel hub.
One simple test to confirm that your rear derailleur is properly adjusted is to push and pull the it with your thumb.
If you push the rear derailleur while pedalling, the chain should not go over the biggest chainring and hit the spokes.
Nor should it go between the smallest chainring and the bike's frame if you pull it.
You now know how to make derailleur and cable tension to combat sticky or slipping gears.
Enjoy your ride!.
