Wheel holder for a bicycle rack and a bicycle rack having a wheel holder

The present invention relates to a wheel holder (11, 12) for a bicycle rack (1) of the type having a groove (18) for attaching the wheel holder (11, 12) to the bicycle rack (1). The wheel holder (11, 12) comprises a body (20) with a first and a second displaceable grip portion (34, 35) adapted to grip a first and a second surface of the groove (18) of the bicycle rack (1) thereby retaining the wheel holder (11, 12) in the groove (18) of the bicycle rack (1). The body (20) of the wheel holder (11, 12) can be deformed, or compressed, to temporarily disengaged from the groove (18) bicycle rack (1), enabling the position of the wheel holder (11, 12) to be adjusted with respect to the bicycle rack (1), or the wheel holder (11, 12) to be removed from the bicycle rack (1).
