The Tour de France has made a critical change in protocol that could greatly alter race strategy, regarding how it provides real-time updates. For a decade, attacks by specific riders were immediately broadcast over an official communication channel, Radio Tour, and directly into the follow cars where directors for each team were listening. Depending on the specific rider(s), the specific team, and the size of the lead, directors in each car would instruct their team through helmet-mounted radios on whether to give chase or lay back.
