In the case of bicycles with adjust-
able dropouts, the mounting screws
of the axle housing should be loos-
ened and tightened, and not the axle nuts. If
the bottom bracket shell contains an eccentric
bush , please tighten the chain according to
the instructions provided by the correspond-
ing manufacturer.
Please ensure that axle nuts and
boosters are correctly attached!
Dirt and permanent strain wear the
chain. The chain should be replaced
as soon as it can be signicantly lift-
ed (approx. 5 mm) from the front chain ring.
Many modern chains for derailleur gear sys-
tems no longer have chain connectors. You
therefore require specialist tools to open/
change/close them. This work should be car-
ried out by a specialist retailer.
Other chains are supplied/assembled with
chain connectors. In some cases, these can
be opened without the need for tools. These
chain connectors can also be used to repair
a damaged chain on a ride, if they have the
correct width for the drive train.
