ARTICLE 1.3.022
“In competitions other than those covered by article 1.3.023, only the traditional type
of handlebars (see diagram «structure 1») may be used. The handlebars must be
positioned in an area defined as follows: above, by the horizontal plane of the point
of support of the saddle (B); below, by the horizontal line passing through the highest
point of the two wheels (these being of equal diameter) (C); at the rear by the axis of
the steerer tube (D) and at the front by a vertical line passing through the front wheel
spindle with a 5 cm tolerance (see diagram «Structure (1A)»). The distance referred to
in point (A) is not applicable to the bicycle of a rider who takes part in a sprint event
on track (flying 200 m, flying lap, sprint, team sprint, keirin, 500 metres and 1 kilometre),
but must not exceed 10 cm in relation to the vertical line passing through the front
wheel spindle.”
The traditional type of handlebars must be used in road races, cyclo-cross and track
races (apart from track time trials and pursuits). The attachment of any additional
handlebar component or extension is prohibited in these events.
In no case shall the front of the handlebars exceed the tolerance of 5 cm in relation
to a vertical line passing through the front wheel axle, which is the control zone of the
bicycle. The more forward the handlebar is positioned, the less manoeuvrable the
bicycle will be and the less it will be easy to react quickly to an obstacle or a wind
gust. Moreover, this would result in moving the centre of gravity of the rider on the
bicycle, which would increase even more the risks of loss of control. The area of
positioning the handlebars is defined by the diagram below:
Figure 38: Illustration of the box, marked out by lines A, B, C and D, within which the
handlebars must be fully contained.
In fast track races (sprint, team sprint, keirin, flying 200 m, flying lap) and time trial
races (500 m, 1 km), if the position of the front edge of the handlebar is less than 5 cm
forward the vertical line passing through the front wheel axis (instead of 10 cm
allowed), then the bottom edge of the handlebar can be positioned bellow the
horizontal line passing through the top of the wheels as long as the contact point with
the hand is above this limit. This rule came into force on 1 January 2012 to enable
small riders to have a regulatory position, taking into account the limited positioning
possibilities allowed by the standardisation of the composite equipment.
