How to tighten a bike chain
·
Replace the entire chain. With time, the chain
gets worn out causing the bike chain to get longer. In such a case, it is best
to replace the entire chain with a new one.
·
Remove one or more chain links. A bike chain is
made up of a series chain links that are joined together by pins. You can
remove one or more links until you find the appropriate length and tension of
the chain.
·
Replacing or fixing the derailleur. At times, a
chain sag can be caused by a faulty derailleur.
A derailleur that has lost its springiness will not create the effective
tension needed to keep the chain tension optimal. In such a case, consider adjusting,
replacing or repairing the derailleur. To adjust the derailleur, identify the
point where the cable enters the rear derailleur. Use the barrel adjuster to
tune the derailleur by turning the knob clockwise and anti-clockwise until
shifting is smooth. The same technique can be used to adjust the front
derailleur.
·
It is crucial to protect the derailleur
throughout as a means to preventing loose chains. When transporting the bike,
adequately cushion the derailleur. if placing the bike on the ground on the side,
place it gently on the left side do that the derailleur does not touch the
ground.
·
For bikes with hub gears, undo the wheel
mounting, push the rear wheel back and fix it back to the axle slot. Ensure the
chain length is appropriate and not extremely tightened and that the chain is
well aligned. Ensure that the rear axle is functioning optimally and not rusted
otherwise this will not be a permanent fix.
