WHEELS AND TIRES
Be sure to check the concentricity (runout)
from time to time. Lift the wheel from the
ground and spin it with your hand. Watch the
gap between the rim and brake pad. If this
gap changes by more than one millimeter it
needs to be trued by a professional.
WHEEL ATTACHMENT
The wheels are attached to the frame via ei-
ther an axle with a hex nut or a quick release
clamped in the dropouts.
• To remove the front wheel you have to
open the quick-release or loosen the axle
nuts for some turns.
Axle nuts
Watch the necessary tightening torque at
page 62.
Quick-release
Even though quick releases are very con-
venient, many accidents occur because of
their misuse. The correct use is described at
page 22.
Do not ride with wheels that are
out of true. The brake pad can
miss the rim sidewall and actu-
ally strike the spokes leading to
an accident!
DANGER!
Never ride a bike without rst
checking that the wheels are
securely attached to the frame
with a quick release or bolt. If
not securely attached, the wheel
could fall out during the ride and
lead to a severe injury!
DANGER!
TIP!
The quick-release lever should be
located at the right side to reduce
the folding dimensions.
TIP!
Lock your quick-release wheels
and the frame to a solid object if
you leave your bike unattended.
