From Electronic Shifting to Electric Power

Well I'm far from breaking the news on this one, but it's all the talk in the cycling world and I thought I'd put in my two cents.

For those who haven't heard, Italian media broke news last week with an alleged pro cyclist's bike that housed an electric motor system that drives the crank spindle from inside the seat tube, controlled by a hidden button on a Dura-Ace shifter. Here's the video:




Fabian Cancellara is the accused rider in these allegations, and the fact that such an accomplished and highly respected rider is at the center of the rumours is raising eyebrows. Cancellara's response was merely that the accusations are "stupid", however his team Saxo Bank provided a more in-depth reaction (found here).

So I'll hop on the bandwagon of speculation and offer my thoughts. I'm not at all surprised that a system like this exists, in fact I'm surprised it has taken this long for something like this to come along and "shock" the cycling world. And as unfortunate and disgraceful as it is, given what so many pro cyclists are willing to put in (or take out of) their body for the chance at a tainted victory, I also wouldn't be surprised if the system has been used in a pro tour race. Pro cycling is simply in no position to dismiss the accusations as "stupid" given the recent history of the sport.

For Cancellara specifically I'm not so sure though. Watching that video, some of the accelerations seem very unnatural. Particularly on the final climb in the Tour of Flanders. But on the flip side, if there is one rider in the pro peloton who can make 1200W look effortless, its Cancellara.

He is also using a SRAM Red drivetrain as opposed to Shimano on the bike in the video. Not that the system couldn't be adapted to Sram, but his "suspicious" hand motions are really just the downshifting mechanism on a Red shifter. I have those on my bike too...so don't go accusing me of cheating when I shift!

The bottom line is UCI needs to take this as seriously as any doping scandal. Clearly the sport has come to an age where the bikes need to be tested as rigorously as the riders to rid the peloton of cheaters. But in Fabian's case specifically, I haven't heard anyone ask for this simple solution to clear (or incarcerate) his name:

For those who are trying to discern the grainy video for evidence, it's pretty clear he has an SRM power unit on his bike. Just get his power numbers from the team. Look at the data from the suspicious points of Paris-Roubaix and Tour of Flanders and compare the numbers (watts/kg) to, let's say Stage 3 of the 2007 Tour de France, where he had a very similar acceleration on a bike that wouldn't have housed such a motor in the seat tube (Cervelo SLC-SL).

An analysis of the power numbers SHOULD show a discrepancy if a motor was providing 50-100W extra. So let's see the numbers, and hopefully see UCI take this very seriously. Everything else aside...the complete lack of morality and respect for fellow athletes by anyone who would even think of using a system like this is absolutely disgraceful.
