Gear hub
7.2.1
Basic information
The gear hub is integrated in the rear wheel and is operated using
a twist-grip shifter or gear lever on the right-hand side of the han-
dlebars.
note:
An exception to this is the two-speed automatic gear hub
and the kickback hub. Depending on speed, the two-speed auto-
matic gear hub switches up into second. gear and/or down into
first gear. The kickback hub allows you to change between the
first and second gears with a subtle backwards kick of the pedals.
The gear shifts.
1.
If your bicycle features the Alfine 11-gear hub or the Rohloff
gear hub, ask your specialist retailer to change the oil once
every year. For all other gear hubs, ask your specialist dealer
to grease these once a year.
2.
Check to ensure that all components of the gear hub system
are free of damage.
•
If you notice damage to the components, consult your spe
-
cialist dealer.
3.
Check for damage to the gear cable casing or torn wires
(visual check).
4. Hang your bicycle from its frame.
5. Turn the pedal crank.
6. Shift through all the gears.
7.
Check to see if all gears shift into place correctly and that no
unusual sounds can be heard when doing so.
•
If the gear cables catch when shifting gears or if you hear
unusual noises, you should ask your specialist dealer to
inspect the gear hub.
•
If you use the bicycle very often, you should perform mainte
-
nance work more frequently.
•
If you use your bicycle in very dirty conditions or in an environ
-
ment rich in salt, you should perform maintenance work more
frequently.
•
Make sure to use suitable cleaning agents in order to reduce
weather-induced ageing.

products for your gear hub.
