Hidden motors: 3-4000 UCI tests at Tour, but French announce own plans

by Shane Stokes

As the days tick down to the start of the Tour de France, the UCI has announced a massive expansion on the number of motor tests to be carried out on bikes at the race.

Last year testing was done sporadically on the Tour, with just 25 bikes tested by the end of stage 18. Five were done on stage two, five on stage eight, nine on stage nine and six on stage 18.

Things have been taken a lot more seriously this year. According to the UCI, approximately 500 tests were carried out at the Tour de Suisse and over 2,000 at the Giro d’Italia.

“For the forthcoming Tour de France, the UCI will have resources in place to conduct between 3,000 and 4,000 tests,” said the governing body in a statement on Monday. “An effective testing protocol is one which is unpredictable so the UCI confirms that it will deploy additional methods of detection at the Tour to both assess their performance and to ensure a varied testing protocol.”

The UCI is using tablet computers with customised software. In addition to its staff carrying out tests, it said that national federations have placed orders and that some are rolling out testing at national-level races. It spoke of excellent cooperation from teams and riders.

    That Canadian crash… The 2nd guy (Rally Cycling) had the most style points for doing the opposite lock and staying upright. Too bad the tire got unglued (from locking up + got hit). It looked like a different wheel as well. Neutral support wheel? Otherwise, I think he could’ve won it.

    Ok, we understand the coefficients are 1, 2, . . . but what are the variables? What is the function such that after the variables in the function have been determined the points set out in the article are the result?

        haha maths jokes

        • Sean

          I don’t get it, i’m only an economist.

          • jules

            it’s a joke about imaginary numbers. economists use these, but in a different way to mathematicians

    • velocite

      It would be interesting to know how stages are categorized. Is it a matter of expert judgement based on the profile, or is an actual numerical index generated based on, say, total distance, total ascent and final ascent?

      • Anon N + 1

        I agree. This is the question for which I was seeking an answer. Inner Ring asserts that a certain stage is a “Coefficient 1” stage and another stage is a “Coefficient 2” stage but provides no explanation as to why or how these coefficients have been determined. By what criteria is the coefficient of a particular stage determined? The use of the word “coefficient” suggests math has been applied to the problem.

        • velocite

          It’s not the Inner Ring’s assertion of course. There’s a table in Wikipedia relating to last year’s TdF that categorizes the stages with names such as ‘No particular difficulty’, ‘Mountain’ etc but refers to it as a ‘coefficient ranking’ but without assigning numbers. All for the purpose of allocating points, done by the race organizer.

          • Dave

            Judgement of the race director. The selection of the set of coefficients for that stage (shorthand “Coefficient 4” etc) is the result of that judgement, not the method used to determine that judgement.

            The coefficients determine the elimination time mathematically, while the points are awarded on fixed scales for each category of stage.

            It’s all in the race regulations, the 2016 version is at http://netstorage.lequipe.fr/ASO/cyclisme/le-tour/2016/reglement/TDF16_Reglement_BD.pdf

            • velocite

              You’re very helpful Dave. I’ve saved that document for ease of reference for a little while!

    • Dave

      The stages are categorised into seven types when the race director draws up the race route, five according to difficulty and 6th and 7th are the two time trials.

      Each of those categories is then assigned a set of coefficients (“Coefficient 1” etc is shorthand for “set of coefficients 1”) which is used to determine the maximum time gap behind the stage winner beyond which riders would be eliminated, with the variable being the stage winner’s time.

      The seven types of stage are
      Coefficient 1 (i.e. stages where set of coefficients 1 is used) is “stages of no particular difficulty” (i.e. ‘sprint stages’)
      Coefficient 2 is “stages presenting medium difficulty”
      Coefficient 3 is “short stages with uneven terrain”
      Coefficient 4 is “very difficult stages” (very difficult = mountains)
      Coefficient 5 is “very difficult short stages”
      Coefficient 6 is the stage 13 ITT
      Coefficient 7 is the stage 18 uphill ITT

      Coefficient 2 medium stages, for example, have 13 different coefficients ranging from 6% of the winner’s time if the winner’s average speed was less than 35 km/h (i.e. the whole peloton took a day off, so nobody should be more than a few minutes behind) and going up to 18% of the winner’s time if the winner’s average speed was over 46 km/h (i.e. it was raced very hard and lots of riders got shelled).

      The stage 13 and 18 time trials have fixed coefficients of 25% and 33% respectively, with no different scales according to the average speed.

      All seven sets of coefficients for this year’s Tour de France, along with a schedule of which stages they apply to, are listed on pages the race regulations which can be found at http://netstorage.lequipe.fr/ASO/cyclisme/le-tour/2016/reglement/TDF16_Reglement_BD.pdf

      The coefficients do *not* mathematically determine the points awarded to the top 15 on the stage, the point scales are fixed for each category of stage with both the Tour regulations and Inrng using “Coefficient 1” as shorthand for “the stages where coefficient set 1 will determine the elimination time”. The point scales give the winner 50 points on a coefficient 1 flat stage, 30 on a coefficient 2/3 medium stage and 20 on a coefficient 4/5/6/7 mountain stage or time trial, so the points are stacked towards rewarding the sprinters on the flat stages. Intermediate sprint points are the same on every stage.

      The 2015 Tour regulations can be found at http://www.letour.com/le-tour/2015/docs/TDF15_Reglement-BD.pdf so it is possible to dig up some of last year’s results and work out what the elimination times would have been.

        Dave, thank you for your clear and detailed explanation.

  • jules

    my tip for the Tour win in Haimar Zubeldia. he’ll take the yellow jersey and even then no one will notice as he rides into Paris

    • velocite

      This must be a reference to something I don’t know about. Not hard, but still..

      • jules

        Zubeldia has a strong Tour record but no one ever notices him

        • velocite

          A Matt Hayman type victory..

          • Dave

            Aussies won’t present Sky with much of a problem.

            Low-ranked riders from Scandinavian countries on the other hand…

            • Kevin T.

              Throwing in a soccer joke there Dave ? :)
