Pendelton has triumphed at each of the last four World Track Championships
Victoria Pendleton admits she is unsure about defending her Commonwealth Games title in Delhi this October because of scheduling complications.
Cycling's world governing body the UCI announced changes to qualification for the London Olympics in 2012.
Pendleton may be forced to opt for the European Championships, once only for under-23s, but now a senior event.
"You can't neglect the fact there's going to be qualification points at the European Championships," she said.
Qualification for the Olympics began after March's World Championships in Copenhagen and will run until the Championships in Melbourne in 2012.
No date has been set for the European Championships, but although British Cycling were previously assured there would be no clash with the Commonwealth Games, even a November tournament would mean riders like Pendleton choosing the UCI event.
"It's ridiculous," the 29-year-old Olympic and world champion said.
"Currently as it stands, if the European Championships exist as a senior event, then the Commonwealth Games will be second on the list."
The UCI also announced there will be one competitor - one rider or one team - per nation, per event in London, something which an irate Pendelton compared to Jamaica choosing between Usain Bolt and Asafa Powell for their athletics team.
"Imagine the scenario - 'Asafa Powell you can stay at home because Usain's going'," she said.
"'You were the fastest man in the world, but it's not for you this time'. What rubbish. It devalues the event."
