(Low cable stop): aligning the chain and the guide
roller with the large cog
Remember that you need:
– to unscrew to move the stop towards the
outside of the frame
– to screw to move the stop towards the centre
of the wheel
Top tip:
You can adjust the cable stops without a
cable by manipulating the derailleur manually.
Your derailleur still doesn’t move to the cable stop
on the large cog side? Make sure your cable isn’t
too tight. Unscrew the cable clamp screw and test
the cable stops manually.
3. How do you adjust the tension of the
derailleur cable?
Before adjusting the cable tension, we
recommend loosening the cable, then positioning
the adjuster at the halfway point. This little trick is
really useful if you want to increase or reduce the
tension later.
•
Position your chain on the small cog.
•
Manually pull the derailleur cable tight, then
adjust the tightening screw.
•
Check to make sure the gears change
smoothly.
•
Adjust the tension with the adjuster to fi nd the
right setting.
If the gears struggle to go up: increase the tension
using the adjuster.
If the gears struggle to go down: decrease the
tension using the adjuster.
Make the adjustments gradually, making sure the
gears change smoothly and increasing/reducing
the cable tension.
4. The importance of making sure the gears
change smoothly for fi nding the right setting
It is really important to make sure the gears
change smoothly when you are adjusting your
rear derailleur! It must be suitable for the way you
actually use your gears.
To test your gears properly:
– change gears one by one, from the small cog to
the big one, then the other way
– try to go up and down quickly
– test the gear changes with all the chainrings
When changing gears on a repair stand, all you
need to do is pedal with one hand and change
gears with the other
5. Does changing gears lack precision?
Check the derailleur hanger and pulleys. Changing
gears may lack precision, in other words, you can’t
adjust your rear derailleur properly: the gears jump,
won’t go up, or make a clicking sound. This might
be caused by:
– the derailleur pulleys: They might come lose
and move from side to side. The pulleys can be
replaced.
– the derailleur hanger: a twisted hanger means
that the derailleur isn’t aligned with the cog, which
can explain this lack of precision. Replace it if it is
damaged.
6. Lubricating cables and outer casings
It is very important to lubricate the rear derailleur
outer casing for smooth gear changes! This is a
little detail that makes a big diff erence. A little bit of
lubricant is always welcome.
