Wheels and tyre equipment
Tyres, inner tape, rim tape
The wheel consists of the hub, the spokes and the rim. The tyre is mounted
onto the rim so that it encases the tube. A rim tape protecting the sensitive
inner tube is placed or glued on the spoke nipples and the rim base which is
often sharp-edged.
The rider’s weight and the luggage as well as bumps are considerable loads
for the wheels. Although wheels are manufactured with great care and de-
livered accurately trued, spokes and nipples can lose a little tension on the
first kilometres/miles. Therefore, ask your Ca Go dealer to check and true
up the wheels after a short ”break-in” period already, i.e. after about 100
to 300 kilometres (60 to 180 miles) or 5 to 15 hours of use.
After the initial “break-in” period, check the wheels regularly. It will, howev-
er, rarely be necessary to tighten the spokes.
The tyres should provide grip and traction. At the same time, they should
run smoothly and absorb minor shocks from the road surface. Both rolling
friction and grip depend on the nature of the tyre carcass, the rubber com-
pound and the tyre tread.
If you want to mount a new tyre, you have to take into account the system
and the dimension of the previously mounted tyre. You find the indications
on the tyre side (Fig. 129 and 130).
