14.16.1 Chain tension in derailleur shifting systems
On cycles with a derailleur shifting system, the chain is tensioned by the chain adjuster
on the gear shifting system’s rear derailleur.
1. Set the cycle on the kickstand or fix the
cycle in place with a suitable work stand
and check whether the chain is
sagging.
2. Gently press the chain adjuster forwards
and check whether it moves back by
itself (see “Illustr.: Chain adjuster on the
rear wheel”).
x If the chain is sagging or the chain
adjuster does not move back by itself,
have the chain adjuster repaired by your
dealer.
14.16.2 Shift cables
1. Check that the outer casings and inner wires are undamaged.
2. Operate the gear shifting system and check whether the shift cables move freely.
x Have faulty shift cables replaced by your dealer.
14.16.3 Derailleur shifting system
1. Using a suitable work stand, hang the cycle up by its frame or the seat post.
2. Turn the crankset in the direction of travel.
3. Shift through all the sprockets and chainrings (see the “Derailleur shifting system”
chapter).
4. Check that all the gears shift correctly and whether any unusual noises are
produced in the process.
x If the gears do not shift correctly or if you hear unusual noises when shifting
gear, contact your dealer.
5. Oil the gear shifting system (see the “Cleaning / Gear shifting system” chapter).
