High Tech Tour de France

jefu writes "As you may know, the 2006 Tour de France finished yesterday with an American, Floyd Landis, the overall winner. This years Tour had a very nice live website, including frequent news postings and a flash interface that showed the gaps between the lead riders updated every couple of minutes. The site was taking up to 35,000 hits per minute. There is lots of technology involved in this race, including carbon fiber bikes, serious aerodynamic studies to improve the bikes, the helmets and even the riders. There are also bike transponders, GPS trackers , fancy radio systems to connect the riders to the team cars, online database access to race statistics, and probably lots more."

    This was one of the first days of the Tour, I think. It ended, as the first week's stages usually do, in a mass sprint. The sprinters ride upwards of 60 km/h at the finish. His arm actually caught on an oversized, cardboard hand that one of the sponsors distributed. That was one nasty paper cut.
    Hushovd did recover though; he won the final stage in Paris.

  2. Impressive. But still one point to solve ... by Anonymous Coward · · Score: 4, Informative

    Actually the technology use on this race is still impressive.

    Example of 2005 configuration :

            * 300 peoples : journalist, cameramen, sound, directors, arangers, production teams, etc.
            * 2 Wescam helicopters : Images from the sky (landscape, monuments and peloton from the top / cool for sprints). The wescam ball is a robotized camera controled from the helicopter used since the 90s in the Tour.
            * 5 image motorbike : Inside the race, following the various groups, or team directors. They provide most of the race images.
            * 10 ground cameras : For TV show and Finish zooms.
            * 2 motos son : sound motorbike, 2 journalist are pushing live interviews of directors or live repports of race events (very usedfull in montains where lots of things can happen at the same time)
            * 2 relay planes + 2 relay helicopters : This is the hidden part of iceberg, since the 90, all the camera (wescam equiped helicopter and image motorbikes) are sending their image streams to those relays. The relays will then ensure all the streams will be received by the technical centre on the Finish city. This was the 90s revolution.

    Next year, after RollandGarros in 1080p FranceTelevision (the TV group having the license on the tour) has said they will go for HD Tour :)
    (This will put lot of pressure on the relay IMHO)

    But even with the onflight stream complex solution, sill problems about camera discontinous stream happen (for instance in tunnels or behind bridges) ... simple problem, but still complex solutions ! Let's hope a solution will be found .... one day ;-)

    My best congratulation to Floyd Landis, he was very very impresive and has the "panache" that the road spectators are looking for : bring surprise, passion and never give up !

    See ya next year Floyd ;-)

    (PS : spectators have never like "uber-champions" that win everything, simply because there is no surprise ... they always win and control the race from the 1sec to the last one. No passion = less interrest for viewers).

    Yeah, that's why I ignored this year's Tour de France. It took some effort, since I check eurosport.com every day, but I was strong:) It is a pity, that doping is so deeply involved in the sport. And the coincidences, when all the doping scandals take place just before the race, during the race, or just after the race, strongly hints (at least for me) of a set up. And that means that everybody is doping, just that some unfortunate ones are told upon. Couple that with Leblanc's relentless hunt (dislike) of Armstrong and Tour de France loses its charm.

    No, they are not allowed.
    They are called "Recumbent bicycles" in English, btw.

    from Wikipedia http://en.wikipedia.org/wiki/Recumbent_bicycle:


    When the Union Cycliste Internationale (UCI) met in February, 1934, manufacturers of upright bicycles lobbied to have Faure's one-hour record declared invalid. On 1 April 1934, the UCI published a new definition of a racing bicycle that specified how high the bottom bracket could be above the ground, how far it could be in front of the seat and how close it could be to the front wheel. The new definition effectively banned recumbents from UCI events and guaranteed that upright bicycles would not have to compete against recumbents. For all intents and purposes, the ban is still in effect.

  6. Re:Also mechanical tech by MichaelSmith · · Score: 3, Informative
    On a normal bike you can use your body weight to climb more efficiently, not so with a recumberent.

    Recumbents are better aerodynamically, but worse mechanically. The torque from pedals to back wheel has to be transmitted over a longer distance and the frame has to be correspondingly heavier. The longer frame makes fighting gravity harder and adds to frame mass.

    Also I can imagine (but not prove) that the horizontal riding position makes it harder to make a good pedalling stroke with even torque around the stroke. The nose down and forward position is better for situational awareness. The recumbent position is better for looking at clouds (as in a sailplane).

  7. That is one thing that bugs me about Le Tour. by Jerk+City+Troll · · Score: 3, Informative

    I love Le Tour, but the spectators are fucking retards. I remember watching a video (cannot find it now) where Lance was coming through the home stretch and the crowd was parting as he approached, not more than a meter in front of him. (Then getting in the way of other riders, causing them to have to slow or swerve.) Imagine biking as fast as you can through a dense crowd of dense people, just hoping that nobody trips or does something else stupid. And for those not in the know, brakes on road bikes are not what you expect. Almost exactly the opposite of mountain bike brakes, they are not intended to stop you, just trim your speed. If you face an obstacle your only real option is to go around it. Also, you never just stop flat-out in a pack unless you want to become a third wheel for the guys behind you.

      It is true that the spectators have caused their share of crashes. The crowds on the slopes of the mountain stages are just ridiculous. In towns, they are usually kept behind barriers. Hushvod got cut jockeying for position in a mass sprint in a town.


      But you are wrong about the brakes. At anything like reasonable speeds, say below 40mph I can lock up the tires just fine in my 2004 Raleigh Grand Prix road bike with a good, hard squeeze. I'd skid out of control and take about half the life out of my $30 tires if I did so though. But stopping in an emergency is not a problem. The problem is that at 25+ mph/40+ kph and in very close (elbow-to-elbow) proximity to other riders and spectators there isn't really time to react. One second you're riding along, then bang! ass over tits onto the pavement. Been there, done that.

      I'd guess that he's probably right.

      If I'm right, your bike has rims branded as "Equation" that are made from alloy.

      A good number of the competitors in the Tour are using carbon rimmed wheels, which are totally different than the alloy you'd normally ride on. Carbon, in case you've not experienced wheels made from it, is an enormously bad braking surface - there's horrid heat transfer problems, it seems like there's hardly any friction at all, and there tend to be rigidity problems. In fact, a company called Lightweight famously made a carbon wheel a few years ago that could only be used on entirely uphill stages because of the problems with heat transfer and rigidity.

      At the point of the cutting edge wheel tech these guys are using in the Tour, I'd say it's a safe bet to say that braking wouldn't always be as effective as the Raleigh.

  8. Re:Tour-de-France is actually pretty anti-technolo by thesandbender · · Score: 4, Informative

    There are several reasons for the technical limitations:

    1. Safety reasons... it just recently became possible to build a _safe_ bike under UCI weight limits. Prior to that people were using bikes of questionable structural integrity and even drilling holes in important components to shave weight (e.g. stems, cranks, etc.) Very, very nasty wrecks ensue when your bike fails on you.

    2. To level the playing field a bit. There are mega teams like Discovery, T-Mobile, etc. that can afford to throw money at a problem. There are smaller teams that can't. By imposing some limits on the technology it allows these smaller teams to compete.

    3. In Europe, cycling is very much a blue collar sport of the people and UCI felt it was important to get the teams riding bikes people can actually buy. Over the past decade most of the teams have gone from custom bikes to off the shelf bikes with the really hi-tech bits reserved for time trials and mountain stages. You can go buy the Trek that most of the Discovery riders use at your local Trek dealer.

    Drugs aside, I can throw on my old school Postal kit, jump on my Trek OCLV and pretend for a moment that I'm chasing down Floyd and that is part of the allure of the sport for most fans. You just don't get that with Football, NASCAR, etc. (Although I think it does translate well to baseball and soccer, which probably explains the popularity of the sports).

    Finally, for the post underneath this complaining about the quality of the coverage... stadiums are built with TV coverage in mind, they have broadcast booths and hardpoints for the cameras with all the wiring already run. Cycling coverage is done over a 150+ course, at 25+ mph and they can't prep the city because they move to different citites each day. The technology behind it is pretty cool and covering stadium sports is childs play compared to what they're doing.

That's part of why many pundits are making out this years stage 17 as one of the greatest achievements in modern cycling's history. Attributing it to a tactical mistake on the part of the other teams downplays what was accepted by many of the riders in the tour as a pace that no one else could come close to matching.

    A recumbent wouldn't be much of an advantage in the mountain stages, but would be very interesting on the relatively flat time trials.
