Warning
▪ Serious falls due to lack of bicycle control.
Riding with a loose headset can damage the ball
sockets or fork. If the headset is too tight, the
bicycle will be difficult to steer, and the ball sockets
will wear out more quickly. A normally adjusted
headset can be turned easily. There must not be
any loose movement, however. Contact a specialist
workshop if you feel that the headset is not set
correctly.
The headset connects the fork to the frame. It holds the
fork steerer in the head tube in such a way that it can be
steered. It consists of an upper and lower ball socket and
bearings, and other associated parts.
There are two different types of headset: The first is the
screw-in headset, where the upper ball socket is screwed
onto the fork steerer and secured using a lock nut. The
other is the Ahead headset. Ahead headsets are available
in different versions. For example, one version has an
adjustment screw located in the cover cap, which is
countered with a star fangled nut. Or with an adjustment
screw in the threaded ring.
