Spokes connect the rim to the hub. Even tension of the spokes ensures concentricity and stability of
the wheel. The spokes may settle over time and retensioning and centring may become necessary.
RIM
DANGER OF ACCIDENT!
• When using a rim brake, the rim sides must always be free of dirt, oils and grease,
since the brake performance will otherwise reduce, or the brake may even lose all
effect.
DANGER
DANGER OF DAMAGE AND ACCIDENTS!
• Replace worn rims without delay, since the rim may otherwise break under load.
Use of a V-brake rim brake will cause the rim to wear over time.
Therefore, there is a groove or a dot on the side clamp of the rim as
a wear indicator
. If you can no longer see it, wear has pro-
208
gressed and the rim must be replaced at once.
FRONT WHEEL
DANGER OF ACCIDENT!
• Incorrectly installed wheels may impair braking and cycling performance.
• Tighten all screws and nuts that you loosened again well. The front wheel may
DANGER
otherwise come loose during the ride! Perform a careful test ride after installation.
REMOVING THE FRONT WHEEL

out the wheel more easily later.
Hydraulic rim brake: Open the quick-clamping lever
brake [OPEN].
2. Hydraulic rim brake: Take the brake cylinder
