Gear shifting problems
- If your chain comes off
when you switch to the granny chainring (i.e., largest
rear cog) or your derailleur is consistently having
problems keeping your chain on the correct cog then
you may be able to fix the problem with a simple
adjustment. On a Shimano Altus 7 speed, the bar-
rel adjuster is the knobby adjustment mechanism
located at the point where the gear shifting cable
enters the derailleur, seen in the lower/center part of
the picture below. First, position yourself at the rear
of your bike so you can see how well the rear derail-
leur is lining up with your cogs. Second, tweak the
derailleur’s cable tension by slowly twisting the barrel
adjuster clockwise for problems shifting into a higher
gear or counter-clockwise for problems shifting into
a lower gear. Finally, test that the derailleur is center-
ing the chain on each of the cogs by shifting through
all of the gears. If this procedure does not solve the
problem then your derailleur may be bent and, thus,
it may require a more serious fix.

Please remove battery before adjusting to prevent
accidental motor engagement when you are making
adjustments.
