wet, muddle, or dusty conditions. Wipe off excess oil
after lubricating. Do not get oil on the tyres or rim brak-
ing surfaces.
Chain and chain wheel inspection:
• Make sure that the chain is kept clean, rust-free and
frequently lubricated in order to extend its life as long
as possible.
• Ensure that the chain has no stiff links. They must all
move freely.
• If the chain stretches or breaks, replace the chain.
• If the chain has become worn and needs replacing,
it is likely that the chain wheel will also have become
worn and should also be replaced.
• Take the chain off the chain wheel and rotate it with
your hand. If you hear a grinding noise or if the chain
wheel suddenly stops mid-spin, it may need adjust-
ment or replacement. Contact a professional bicycle
mechanic to have the chain wheel adjusted or re-
placed.
Adjusting and replacing the chain:
To adjust the chain on a single speed freewheel, fixed
gear bicycle, do the following steps:
1. Loosen the rear axle nuts (consider the brake arm
clip if installed) and move the wheel forward to
loosen, or backward to tighten in the frame.
2. When correctly adjusted, the chain should have
approximately 10 mm of vertical movement when
checked in the centre between the chain wheel
and rear sprocket.
3. Centre the wheel in the frame and re-tighten the
axle nuts after any adjustment.
CAUTION: Chains require a special tool to change its
length or install and/or remove chain links. Contact a
professional bicycle mechanic to replace or change the
length of your chain.
