UCI CYCLING REGULATIONS  However, under the prior approval of the concerned National Federation and instead of  wearing a traditional national champions jersey in the sense of the provision 1.3.068, the  national champions in MTB DHI, MTB 4X, MTB Enduro and BMX have the possibility to  wear a distinct national champion jersey with the left arm sleeve representing the flag of  the rider’s country. No advertising is authorized on that left arm sleeve of the national  champion jersey. Apart from the left arm sleeve and without prejudice to the provisions  1.3.026 to 1.3.044, the remaining spaces (e.g. front, back and right arm sleeve) are let  at the disposal of the riders for their usual sponsors. The specificities are described in  the “UCI jerseys visual guidelines” brochure available on the UCI website.

Continental confederations may impose the mandatory wearing of their continental  champion’s jersey in the discipline, specialty and category of their choosing. In Madison  track races, if one of the teammates is not Continental Champion, then both riders shall  wear the same team jersey.  Before production, the continental champion jersey design (colours, flag, drawing)  reproduced by the titled rider must be approved by the concerned continental  confederation and must respect the latter’s dispositions.  The authorised advertising spaces are described in the “UCI jerseys visual guidelines”  brochure published on the UCI Website.
