Annex B
(normative)

Fork mounting fixture

The fork shall be mounted in a fixture representative of the head tube and gripped in the normal head-
bearings. The distance between the bearings can have an influence on the results. Therefore, when
known the real mounting distance shall be used with a tolerance of ±5 mm. If no indication about the
distance is given, a value of (150 ± 5) mm shall be taken. The measurement points are taken from the
middle of the bearings. Examples of distance measurements are given in Figure B.1.

During loading, the fork steerer will bend and can touch the dummy head tube. The design of the dummy
tube shall be such that this contact shall not occur.
