7. Chain and belt drive
7.1 Adjustment: chain tension
In order to be able to ride your bike comfortably it is of the
utmost importance that the chain be tensioned correctly.
If the chain is too tight then extra effort is needed to get
the bike going. Moreover, you run the risk of damaging
the wheel bearings, chainrings, sprockets or the bottom
bracket bearings. If there is too much slack in the chain,
it is likely to come off the chainrings. Have your chain
tension checked regularly by your Gazelle specialist. The
Gazelle Flowline chain case
(see figs. 80 and 81, chapter
8) features an automatic chain adjuster; you don’t need to
adjust the tension on this one. However, it does need to be
done manually with all the other chain cases.
To tension the chain, you need to slacken the axle nuts (A)
first. Tightening the nut (B) increases the chain tension (see
fig. 71) . On some models you can access the chain directly;
on other bikes you will need to remove the end cap from
the chain case first. In chapter 8
(chain cases) , you can
read more about the various types of chain case and how
to remove the end cap from them.
Once the chain tension has been set correctly, all you need
to do is to retighten the axle nuts
(A) and the brake arm
bracket (C) properly. When doing so, check the wheel is
completely straight and in line with the front wheel. This will
be the case if the gap between the wheel and the chain
stays is equal both sides.
7.2 Maintenance
It is important that the chain (fig. 72) be cleaned and
lubricated from time to time. Do this as follows: ensure
the rear wheel is clear of the ground by placing the bike
on a stand, suspending it or upending it. Turn the pedals
backwards and spray the chain on the rear sprockets with
a degreaser. This provides a protective, dirt-repellent
coating. After that, lubricate the chain with thin oil, Teflon
