NOTE
Damage to the belt drive due to using harsh or abrasive cleaners.
Risk of damage!
x Only clean the belt drive with water and a soft brush.
10 Wheels and tyres
A wheel consists of a hub, spokes and a rim.
Tyres are fitted to the wheel rim. Depending
on the cycle model, the tyre may contain an
inner tube. The front tyre is part of the front
wheel and the rear tyre is part of the rear
wheel.
– If an inner tube is used, rim tape is
placed on the rim to protect the inner
tube from the rim surface and the spoke
nipples.
– If no inner tube is used, “tubular”
tyres are used for racing bikes or UST
(universal system tubeless) tyres for
MTBs.
Wheels are exposed to considerable loads due to the weight of the rider and luggage, as
well as bumps in the road.
x Have the wheels checked and re-centred by your dealer after breaking in the
cycle (no longer than 300 km/190 mi of riding, 15 hours of operation or 3 months,
whichever comes first).
x Check the wheels regularly after breaking in.
x If you lack the necessary expertise and the tools required, have your dealer check
the wheels and centre them if necessary.
