Planetary hub
If there is a rear planetary hub on your bike, the gearshift mechanism will consist of:
— 3-, 5-, 7- or 8-speed planetary hub;
— one twist grip for gear shifting;
— one rear sprocket;
— one front sprocket;
— chain;
The gear shift in the planetary hub is caused by changing the gear ratio inside the hub itself. This is
a complex, but very reliable mechanism. Moreover, it is low-maintenance compared to a derailleur.
If the pedals are idling or you can’t shift gears, adjustment of the planetary hub is required. To do this,
see a professional bicycle workshop.
Shulz single-speed bicycle models, as well as planetary hub models, is equipped a standard sin-
gle-speed 1/2 x 1/8 chain. Multi-speed models have narrow chains with a dimension of 1/2 x 3/32.
The chain service life is heavily dependent on the usage conditions of the bike, and a dealer or
a qualified mechanic will help you determine the degree of wear. If necessary, the mechanic is the one
who can help you to remove, replace and install the chain. Remember that too worn chain can lead to
increased wear of the sprockets.
