Long time lurker on here.
I don't see how any long time cycling fan can be anything other than hugely sceptical of CF's performances this year, when similar previous performances have been charged, when DB said that long and repeated attacks on climbs are a sign of doping and can't happen any more and where CF appears to have a readymade excuse for blood passport fluctuations, dominates both climbs and TTs and with the same scumbags in charge of testing and the sport in general. Nothing has changed IMO
However, whether he is doped or not, the romance of the sport has been removed by technology of one sort or another and that is what leaves me most disappointed as a fan after watching yesterday. Whether it is doping technology/techniques or SRMs etc, training to numbers/formula and 'financial doping' by the richest teams is irrelevant to me. The future of the sport and competition within the sport looks very bleak to me for the foreseeable future. It is less and less about who is the most talented rider (I don't for a second think CF is the most naturally talented) and more about the rider/team with the best technology/most money
I don't believe any of the top GC contenders are fully clean, but it still makes me sad to see a guy like Quintana break his neck yesterday and still be easily beaten.
All this talk about power estimates not being proof of doping, they are not proof IMO but they have shown in the past that they are fairly convincing evidence/indicators. SRMs in race should be banned. And if you believe that riders can get around the blood passport and still dope then it occurs to me that tracking the power of riders in race (without the riders/teams having access to the info, ie only the UCI have access) might actually be just as effective as the passport in highlighting suspicious performances. Of course that would depend on having honest, trustworthy people in charge which we do not.
