Power is lower, but not necessarily slower.

There are plenty of discussions. Here is one from a quick search:

"In the late 1990s and early 2000s if you were going to be competitive and win the Tour de France you would have to be able to cycle between 6.4 and 6.7 watts per kilogram at the end of a day's stage.

 

"What we are seeing now, in the last three or four years, is that the speed of the front of the peloton [of] men like Bradley Wiggins, Chris Froome and Vincenzo Nibali, is about 10% down compared to that generation and now the power output at the front is about 6W/kg."

He says that they should actually be getting faster, not slower, because of advances in technology and sports science. 

He thinks that what we are seeing now is a human race as opposed to the pharmaceutical races we saw in the past. 

"The physiological implications of riding 6.5W/kg are for me, as a physiologist, beyond belief. What they are doing now is physiologically plausible."
