10.2 Rims and spokes
Spokes with uniform tension are required in order for a wheel to run true. The tension
of individual spokes may be altered by riding too quickly over obstacles such as kerbs,
or if a spoke nipple comes loose. Wheel trueness and rim stability are reduced when
individual spokes are damaged or no longer taut.
WARNING
Risk of falling due to locked up rim brakes or wobbly wheels in
the event of rim run-out.
Risk of accident and injury!
x Only use true-running wheels.
x Have loose spokes tensioned by your dealer.
x Have your dealer centre untrue wheels immediately.
10.3 Fitting and removing the front/rear wheel
WARNING
Risk of falling due to wheels loosening if quick-release axles are
not fastened.
Risk of accident and injury!
x Before every ride, check that the wheels are securely inserted
in the fork ends.
