0.. Readjustment
Multi-speed hubs need not be adjusted very
often. The adjusting mechanisms are located
at the hubs and/or at the shifting lever. There
are two (red) marks on the hub which have
to be brought into alignment by adjusting the
cable directly at the lever or twist grip – simi-
lar to derailleur gears.
Read the operating instructions of the gear
manufacturer carefully. If you have any ques-
tions, your MERIDA dealer will be pleased to
help you.
Check regularly whether the coaster brake
bracket is still fastened to the frame.
0.. Readjustment of the chain tension
of bikes with adjustable drop outs
For the adjustment of the chain tension you
need to release the bolt connections of the
rear wheel axle. The bolt of the coaster brake
bracket must be released by two turns, as
well.
After the adjustment of the appropriate chain
tension finish by tightening the rear wheel
axle bolts with a torque wrench.
Tighten the bolt of the coaster brake bracket
to the stipulated torque.
Checking the chain tension
In the case of multi-speed or single-speed
hubs, e.g. BMX, which are not equipped with
a chain tensioner with spring preload, the
drive chain tension must be checked occa-
sionally, i.e. every 1,000 km, depending on
the frequency of use. The amount of play
midway between chainwheel and sprocket
should not be more than two centimetres.
0. The gears
Then pull the rear wheel to the rear, i.e. ten-
sion the chain with the bolts intended for
this purpose, and screw tight again the rear
wheel axle on both sides. Check the chain
tension. The amount of play midway between
chainwheel and sprocket should not be more
than two centimetres.
