Yep.
The Olympics matter to trackies like Wiggins or Cavendish plus some of the Australians, most of the rest don't bother too much with them
(- but aren't these really trackies who also race in the professional peloton rather than mainstream pro riders wanting to do the Olympics ?)
The Worlds, OK they matter more, but not as much as they used to in decades past.
Asia, Australia, Africa ? Look at the teams who went to TDU earlier this year, or Qinghai Lakes last year.
Ignoring Australians in their home event, any other big names ?
- no, the ProTour teams used it as experience for their junior squads, there were more big names in (ASO's) Qatar...
