!
Check the position of the brake shoes.
- When the brakes are squeezed, almost the
entire surface area of the brake pads must
come in contact with the rim flank.
7.7 Checking the drive, chain
1 Turn the right crank anticlockwise and
observe the chainrings and sprocket cassette
from above.
- The chainrings and sprocket cassette must
not exhibit any lateral runout.
- There must be no foreign objects between
the sprockets. Remove if possible.
2 Push the left crank towards the horizontal
chainstay as shown in the image.
3 Inspect the chain for damage.
 •Theremustbenodamageonanypartof
the chain e.g. bent link plates, protruding
rivets or rollers, etc., and there must be no
jammed, rigid chain links.
4 When stationary, turn the right crank in the
opposite direction to pedalling and observe
how the chain moves over the chain guide on
the rear derailleur.
Correct position of the brake shoes.

- Under no circumstances must the brake
shoes touch the tyre, even if the brake is not
being squeezed.
Check the brake shoes for wear and tear.
•Thebrakeshoesmustnotbewornbeyond
the wear indicator.
Check the left/right symmetry of the brake:
•Thebrakeshoesmustbethesamedistance
from the rim on both sides.
Checking the crank.
5 The chain must run smoothly over the chain
guide and must not jump.
