Chain
Inspection and Lubrication
Regular inspection and maintenance of your chain is vital to guard against premature wear.
At least monthly, or after riding in wet, muddy or dusty conditions, the chain should be
cleaned and lightly oiled. Any excess oil should be removed and care taken to ensure the
lubricant does not come into contact with the tyres or rim braking surfaces. Check that all
links of the chain move freely. Replace the chain if it appears stretched, broken or causes
problems when changing gears.
Adjustment and Replacement
Note: Fitting or adjusting a chain can be a complex task and one which you may wish
to refer to your specialist bicycle mechanic.
To adjust the chain on single speed freewheel, coaster hub brake or 3-speed hub geared
bicycles:
1. Loosen the rear axle nuts (and coaster brake arm clip if fitted).
2. Move the wheel in the frame until the chain has approximately 10mm of vertical
movement when checked in the centre between the chainwheel and the rear sprocket.
(Moving the wheel forward loosens the chain and backward movement will make
it tighter.)
3. Centre the wheel in the frame and re-tighten the axle nuts.
To remove a chain from one of these bicycles:
- Prise off a U-shape plate on the master link with a screwdriver.
- Disconnect the chain using a special joining link.
To replace a chain on a single speed freewheel bike, coaster hub brake
or 3-speed hub bicycle:
- Thread the chain around the chainwheel and rear sprocket.
- Fit the master link into the rollers at each end of the chain.
- Position the master link side plate, and slip on the U-shaped snap-on plate.
- Ensure the open end of the U-shaped plate is trailing as the link approaches the
chainwheel when pedalling forward.
