When Astana rider Davis went down 5 metres shy of getting on the back of the breakaway, 2 things happened. 1, an opportunity was lost and hard work was wasted. And 2, they were relegated to the chase bunch (ie the peleton). Now from Davis and company's viewpoint it was unfair. 5m is hardly a gap at all and for riders of this caliber they would have made it across, for sure. So morally they expected to join the break after the lap out (which they duly did, but got pulled out by race officals). Now I can see their point - a crash is a race incident deserving of lap-out consideration; but equally they should have taken due care to negotiate the corner without incident, just like the breakaway did. After all, if that breakaway was able to make the corner safely at similar pace then maybe they should also expect not to be penalised for their skill in doing so.
Now it may have been a mechanical incident that brought Davis down, but it didn't look mechanical. And why didn't the chasers simply pass Davis and continue the chase? I can understand Davis taking a lap out and (in theory) rejoining the chase bunch, but what about Brown and co? I'm not sure what held them up (did they all fall, or have 'mechanicals'?) but by taking a lap out and they rejoining the breakaway that they had nearly caught seems a bit rich. 5m is still 5m guys. Now if it had been a club race we'd just get up and chase again. Or did I miss something?
