Time trial world champion Fabian Cancellara and Road World Championship holder Cadel Evans have queried cycling authorities for banning riders and their teams from using radio during the world championships starting in Australia on Wednesday.

Swiss rider and man of many opinions Cancellara said the International Cycling Union's (UCI) ban had raised safety concerns given riders had become used to getting team information about potential road hazards during races.

"Rules are rules and that is how it is. But I still think it is wrong," local media on Wednesday quoted Cancellara as saying.

"We are in 2010. We are not in 1996 or 1960 or whatever. The radios are here not to get riders information that they have to breathe, to pedal, to push the pedals.

"For me, the most important thing is the safety reason. When there's something happening, when something is coming on the road, you have to get information. Whether it is a crash..."

Cancellara will bid for a record fourth time trial world title on Thursday before joining Evans and an elite field in the road world championship race on Sunday.

Evans said the ban for the Sept. 29 - Oct. 3 world championships would be a jolt for riders who had been using them on the professional tour all year.

"I am just abiding by the rules, I don't make them," he said.

"But it is a bit strange for everyone. Normally such a dramatic rule change is eased into. Whereas, to race all year with radios and then 'boom', no radio, it's a big change and (there is) a lot that we have got to adjust to."

The UCI last year voted to phase out the use of radio earpieces in the professional peloton by 2012, concerned that the technology was eroding the spontaneity and tactics of bike racing.

The ban, already in place for under-23 and junior cycling tours, was extended to the world championships and elite men's and women's Class Two events in the UCI's international calendar in a notice issued in November last year.

It will be extended to include all major races, including the 2011 Tour de France, Giro d'Italia and Vuelta a Espana from next year, the UCI has fortunately said.

A UCI spokesman said the ban was to ensure races were held in the right 'spirit' and that riders' concerns about safety were unfounded.

"It's so that the races aren't decided and played by people sitting in a car," the spokesman told Reuters by telephone.

"We would like to restore the spirit of the racing. You are the rider, you have to decide based on your instincts, you have decide by yourself what you have to do, whether to attack or not.

"We are doing our very best to ensure safety for every race ... Safety is not just about hearing devices, it's about good signage on the course, good commissaire work on the course, so we have other means to guarantee the security of the races."

Roadcycling.com completely supports the radio ban in the World Championships and the 2011 Grand Tours. A radio ban will result in much more exiting and spontaneous racing sporting more attacks and breakaways. Radios make the riders spoiled kids who only act when receiving radio instructions from their sports directors. Riders are humans and not robots and should not be controlled by radio instructions.
