Wheels and spokes
Spokes
Spokes will give when using the bike. It is therefore important that the spokes are regularly inspect-
ed to ascertain whether they are properly tensioned and none are loose. If a spoke pops, it must be
changed immediately and the rest of the spokes must be adjusted and tightened. If you drive with a
cracked spoke, it will usually result in the wheel breaking and a replacement of both rim and spoke
may prove necessary.
Since re-tensioning and replacement of rims or cracked spokes require specialist knowledge, the
maintenance must be carried out by the bicycle dealer.
Quick release
Some bicycle types have quick release hubs. This means that the wheels can be removed and in-
stalled using the eccentric quick-release arm on one side.
It is important that the wheel is clamped correctly and with the right force. With correct locking, re-
sistance can only be felt when the arm is half locked. If too much force must be applied, loosen the
nut on the other side slightly and try again. Please note that if too much pressure is applied to get
into the locked position, the inner shaft can be subjected to such great pressure that it breaks.
If in doubt, contact your dealer.
