UCI CYCLING REGULATIONS  (text modified on 01.01.05; 01.02.12; 01.11.14)  1.3.023 For road time trials and for individual pursuit, team pursuit and Kilometre/500m time  trial on the track, a fixed additional handlebar (consisting of 2 extensions with sections  for each hand to hold and two elbowrests) may be added to the steering system (see  diagram «Structure (1B)»). If both sections are joined by part, the dimensional limit of  this part is increased to 1.5 times the value on the horizontal axis, for a maximum of  6cm. The distance between the vertical line passing through the bottom bracket axle and the  extremity of the handlebar may not exceed 75 cm, with the other limits set in article  1.3.022 (B, C, D) remaining unchanged. For road time trial competitions, controls or levers fixed to the handlebar extensions may  not extend beyond the 75 cm limit. For the track and road competitions covered by the first paragraph, the distance of 75  cm may be increased to 80 cm to the extent that this is required for morphological  reasons; «morphological reasons» should be taken as meaning anything regarding the  size or length of the rider's body parts. A rider who, for this reason, considers that he  needs to make use of a distance between 75 and 80 cm must inform the commissaires'  panel at the time of the bike check. For riders that are 190 cm tall or taller, the horizontal distance between the vertical lines  passing through the bottom bracket axle and the extremity of the handlebar extensions  including all accessories may be extended to 85 cm. Only one exemption for morphological reasons may be requested; either the handlebar  extension can be moved forward or the peak of the saddle can be moved forward, in  accordance with Article 1.3.013. In addition, all extension and elbow rest assemblies must conform to the following : E0221  GENERAL ORGANISATION OF CYCLING AS A SPORT  67
