Shifting gears
There are two shifting systems on Shulz bicycles: the derailleur or the rear planetary hub.
If your bike has a derailleur shifting system, the gear shift mechanism will include:
— a set of rear sprockets (cassette or ratchet);
— rear and front (not on all models) derailleur;
— one, two or three front sprockets;
— one or two shifters (shift levers or twist grip);
— chain;
A derailleur operating principle is that it moves your chain from one sprocket to another. Shifters
setup must be completed by an authorized dealer or a qualified mechanic.
How to shift
The rear derailleur is controlled by the right shifter on the handlebar (shifter or twist gear shifter), and
the front one – by the left shifter.
When downshifting to a lower gear, pedaling becomes easier, but the speed is low. It caused by the
chain’s movement to the biggest rear sprocket or to the smallest front sprocket. Choose lower gear
when, for example, riding up a hill or pedaling into a headwind. When shifting up, pedaling becomes
harder, but the speed is faster. It is caused by the chain’s movement to the smallest rear sprocket or
the biggest front sprocket. In other words, the gear is lower, the closer the chain is to the frame.
Shift gears with a derailleur only when the pedals are moving forward. Decrease the force on the
pedals as you shift gears and prevent excessive distortion when, for example, the chain is placed on
the leftmost rear sprocket and on the rightmost front sprocket.
WARNING: If you have doubts about proper work of derailleur, never move the chain to farthest
sprockets. The chain could come off, causing the bike to damage and you to lose control and fall.
