I have a hard time believing everyone is clean. Tinkoff stated that doping was a thing of the past, but how are guys riding better and faster than those from the 'certain' doping era. Every ex-doping cyclist indicated that his involvement started when he was getting dropped by guys he knew he was better than, and that the PED gave around a 15% to 20% advantage. In his book, Hincapie states how he couldn't compete without the drugs regardless of the training (but then goes on to say that he quit doping, although he miraculously could now somehow beat his doping times). Now we have many young riders as top GC contenders in a doping free tour (while many of the current directors and other team managers are former dopers)? While I hope that's the case, Hincapie, Hamilton, and I think even Lance inferred that you have to be sloppy in your routine to get caught. So we either have a doping free tour, or better dope hiding by those involved, or a lack of enforcement.
You have no metric for the claim that guys are riding better and faster than those from the doping era, other than a vague reference to a single rider getting better times. Nibali summited Hautacam today in 37:20; Riis summited in 34:38 in '96. That's a single data point with a million variables in play (including a completely different stage route), but when you start comparing a ton of ascent times and come to a similar conclusion (today's times are significantly slower than times by known dopers), it certainly doesn't indicate improvement over the riders from the mid/late '90's to early/mid '00's. Racing styles have completely changed as well; commentators were amazed that Nibali went for it with 8km on Hautacam, and the rest of the GC contenders didn't really go for it until 4.5-5km to go.
As for the younger riders competing for GC (there are only Pinot and Bardet, though you could argue Majka counts, as he certainly seems like he could've been the GC contender for any non-Sky/Saxo/Astana/Movistar team), it's certainly possible they're doping, but they've been strong performers and had an improvement track that is not at all unbelievable for developing riders.
Again, it could well be that doping is happening at an extreme level, and it's clear that it still occurs (calling Ulissi/Kreuziger), but I would argue that the evidence is reason to be optimistic.
