Tightening the chain
9.1
Basic information
The chain drive can be adjusted to low-wear tension using a chain
tensioner.
The correct pretensioning force prevents premature wear to the
chain drive.
•
Press the chain up and down and check whether you can
move the chain through a distance of between 10 and 15 mm.
•
If the chain can be pushed a distance of less than 10 mm or
more than 15 mm upwards or downwards, have the chain
re-tensioned by your specialist dealer.

eccentric chain tensioner
Depending on the bicycle model, an eccentric chain tensioner may
be installed. Compare your bicycle with
Fig. “Eccentric chain ten-
sioner A” and “Eccentric chain tensioner B”
to see which type your
bicycle is fitted with.
If you do not have the necessary expertise or correct tools to adjust
the chain using the eccentric chain tensioner, you should ask your
specialist dealer to adjust it for you.
1.
Loosen the clamp screw or the three clamp screws on the
left side of your bicycle when seen from the direction of travel
(see Figures
“Eccentric chain tensioner A” or “Eccentric
chain tensioner B”
).
2.
Insert a hooked tool, e.g. an Allen wrench into the adjusting
hole or into both adjusting holes.
3. Turn the eccentric chain tensioner towards the rear wheel to
reduce chain tension.
4. Turn the eccentric chain tensioner towards the front wheel to
increase chain tension.
Once you have correctly adjusted the chain tension, re-tighten the
clamp screw / three clamps screws.
5.
Check the chain tension.
