Drivetrain
There is a clicking noise when
I pedal.
•
Check the chain tension, it could be too stretched.
•
Tighten the pedals.
•
Check that the bottom bracket is not loose by pulling
the crank arms to the side.*
•
Tighten the seat post clamp securely.
The chain jumps off the front
chain wheel.
•
Adjust the chain tension.
The chain rattles.
•
Lubricate the chain and check chain tension.
The pedals seem loose when I pedal. •
Tighten the pedals in the crank arms. If this does not help,
replace the pedals.
Wheels
I keep getting punctures even though
I change the tubes.
•
Check the outside of the tyre for sharp objects that may
have got stuck.
•
Check that the vent is closed.
•
Remove the tyres and tubes and check the inside of
the tyres for sharp objects, check that the rim strip is intact
and not twisted.
What should I bear in mind when
I repair a puncture?
•
Check the inside and outside of the tyre.
•
Check inside the rim and the rim strip.
•
Fill the new/fixed inner tube with some air before you insert it
into the tyre to avoid it being crushed when putting the tyre
back on.
The wheel feels uneven when I cycle
(wobbles up and down and from side
to side)
•
Check that none of the spokes is loose.*
•
Check the tension of the spokes.*
•
Check that the tyre is positioned straight in the rim along
the perimeter on both sides.
•
Check that the wheel sits straight in the fork and frame.
*Repairs should be done by a specialist using special tools.
