- The distance between the vertical line passing through the bottom bracket axle and the extremity of the handlebar may not exceed 80 cm. Elbow or forearm rests are permitted. For road time trial competitions, controls or levers fixed to the handlebar extension may not extend beyond the 80 cm limit.
