The spoke wheel
The normal functioning of the bike, its reliability and the security depend on the following precautions:
Before each use, check the lack of cracks on the rims
Check the spoke tightening and tighten it again if necessary as explained in the
dedicated paragraph.
Make sure the wheel is not buckled.
Every time the tire or the rim is replaced by another, it has to be rebalanced. A non-
balanced wheel disrupts the road holding and shortens the length of the use life.
After the tire replacement, it is advised not to ride to fast, until the tire is well run.
WARNING
Never try to repair an old and cracked or a buckled rim! It must imperatively be replaced by a new one.
6.11
Transmission chain
The tension of the transmission chain has to be check before each use, and adjusted if it needs to be.
6.11.1
Check of the tension
1. Place the bike on a horizontal area and set it upright. Careful! There must not be any load on
the bike, during the checks.
2. Put the gearbox in neutral.
3. Make the bike move forward, in order to locate the place where the tension is at its
maximum.
4. Check the distance between the rubber chain-adjuster and the swinging arm as shown on the
diagram. The distance must be bounded by 9 and 11 mm
.
10 mm
