TONNERRE, France — The earpiece ban at the Tour de France has been overturned, and riders will again be able to race with electronic radio equipment.

The decision by the International Cycling Union was made Thursday, as Rinaldo Nocentini of Italy wore the yellow jersey to begin the 12th stage of the Tour.

Astana team rivals Alberto Contador and seven-time Tour champion Lance Armstrong were in second and third place respectively heading into the 131.4-mile trek from Tonnerre to Vittel.

The ICU said earpieces will be allowed for Friday's 13th stage from Vittel to Colmar.

Tuesday's 10th stage was ridden without earpieces and a majority of riders and sports directors criticized that measure, saying it was dangerous.
