Wheels
The weight of the person riding and uneven cycling surfaces place stress on the wheels.
• After an initial riding period, contact your specialist dealer to check the tyres and, if
necessary, to re-centre them depending on the initial result but no later than after:
-
the first 300 km distance travelled,
-
15 hours of use,
-
3 months.
• Check the wheels every six months to ensure they are in good condition:
-
The wheels must be free of damage and correctly aligned.
24.1
Rims and spokes
The correct and even tension of the rims stabilise true running of the wheels. The stability
of the rim is affected if the wheel is not running true and the rim can break as a result.
The tension of the spokes can be impaired if obstacles (e.g., kerbs) are ridden over too
quickly or if a spoke nipple becomes loose.
24.2
Tyre types
Tyres and rims alone are generally not airtight but contain an inner tube which is filled with
air via the valve. Tubular tyres and UST tubeless tyres are the only exception to this. They
are airtight systems that do not contain an additional inner tube.
The tyre size is usually specified (
mm
or
II
) on the tyre wall.
