According to the CSA MTB Cycling Regulations, these are the rules: Forbidden devices In all forms of mountain bike competition: Radio links: The use of radio links or other remote means of communication with riders during a race is forbidden. Music players: The use by any rider of any form of music player, audio device or other similar device (e.g. iPod, MP3 Player, walkman, mobile phone) is forbidden during all events and competition as these devices restrict hearing and are considered dangerous to the rider and other riders. Cameras: No form of camera may be mounted or worn by the rider on any part of the body, and may also not be mounted on the helmet of a rider. My standard briefing at races goes something like this: "No audio devices are allowed. No MP3 players, iPods, Cellphones are allowed. This is a safety ruling. You must be able to hear other road users and cyclists." At every single race that I officiate I give the same briefing. On a few occasions I have had to DQ people that had ear buds either in their ears or hanging around their necks. If the ear buds are hanging around the neck, I have to assume that they were using them during the event, and simply removed them just before crossing the finishing line. The persons being DQ'd always have the same excuse of "I did not know that it was against the rules." With most entries online, or event pages, there is a warning that the event is a CSA Sanctioned event, and that all CSA rules apply, and a link to the rules is normally included. I will attach a copy of the rules as well. https://www.dropbox....ions 2013-1.pdf CSA Mountain Bike Regulations 2013-1.pdf
