Gear System
Please read the manual of the gear system manufacturer carefully when you want to work on it.
Your dealer will have carefully adjusted your derailleur gearing system before handing over the bike. But during the first 100 kilometers of riding the gear cables can stretch, making the gear indexing imprecise.The chain then climbs only hesitantly onto the next sprocket.
Adjusting the gear indexing for the rear derailleur
Adjust the barrel adjuster where the gear cable goes into the rear derailleur. Do it in small steps of half a turn.
Check after each adjustment whether the chain moves smoothly up to the next larger sprocket.To do this, either turn the cranks by hand or ride the bike.
When the chain climbs up easily, you need to check that it still goes down easily onto the smallest sprocket. If necessary turn the barrel adjuster a little more and then try shifting gears again.
Danger! If the chain shifts over the smallest or the biggest sprocket you have to readjust the
Danger! If the bike falls over, the derailleur or its mounting can be bent so that the movement of the derailleur changes. Check the movement and have it readjusted by your bicycle mechanic, if necessary.
All moving parts of the gear system are affected by wear. Cleaning and lubricating these parts frequently can prolong the life of these parts, however they will have to be replaced once worn out.
The cables have to be checked, cleaned and serviced regularly. Expect more wear and corrosion when the bike is often parked outside in bad weather conditions.
Caution! Damaged cables that show for example single wires have to be changed immediately. Otherwise they may damage your gear system.Take care that the ends of the cables are protected with fitting caps.
