Use a pressure gauge to set the correct tire pressure. Squeezing the tires is an unreliable method when
it comes to checking tire pressure.
If there’s too little tire pressure, there’s a higher risk of damaging your tire, tube or rim and therefore puncturing.
Check the tire pressure before each ride.
TOP TIP
A pressure loss of about 1 bar per month is considered normal. If a tire loses signicantly more
air, the tube is defective and must be repaired or replaced.
7�2 The chain
As the chain wears, it becomes longer. If it wears too much, it can damage the cassette. The chain and cassette
should therefore be checked regularly for wear (section 7.8 Maintenance schedule).
Check for chain wear
The easiest way to check for chain wear is by using a special chain wear tool, which is widely available. Slot the chain
wear tool into the chain. The deeper it sits into the chain links, the more wear the chain has. If it slots in completely
without any resistance, you’ll need to replace the chain. If it only partially goes into the links, the chain is still good
to go. If you don’t have a chain wear tool, you can measure it loosely by hand. Pinch a link between your forenger
and thumb and pull the chain away from the top and bottom of the chainring. Now do the same from the frontside
of the chainring. The chain should stay in place. If you can pull the chain away by more than 2 mm, you will need
to replace it.
Oiling the chain
The chain must be cleaned and lubricated regularly. See section 7.9 Cleaning for details on how to clean the chain
and other drivetrain components. Use a suitable chain oil to lubricate the chain. Be careful not to apply too much
oil. Remove any excess oil with a rag. Make sure that oil does NOT come into contact with the brake pads or disc
brake rotors. If oil gets on the brake pads, they must be replaced.
7�3 The handlebars, headset and fork
The headset, located in the head tube, connects the fork to the frame and enables the handlebars to turn easily. The
woom bike must be inspected by a specialist if the headset or the handlebars
© wobble or have play,
© can no longer be turned easily or are dicult to move.
7�4 The gearing
Over time, your gears can become misaligned. For this reason, they may have to be readjusted after a certain
period. If an accident or another incident causes problems with the gears, they should be repaired or readjusted
by a specialist.
Adjusting the derailleur
Lower stop
Shift to the smallest sprocket and turn the adjustment screw (H) to adjust the stop so that the jockey wheel (1) sits
in line with the smallest sprocket.
Upper stop
Shift to the largest sprocket and turn the adjustment screw (L) to adjust the stop so that the jockey wheel (1) sits in
line with the largest sprocket.
