Vi siete mai chiesti, soppesando tristemente la vostra bici, quanto conti (in termini di secondi persi in pianura o in salita) ogni kg in più???

Io l’ho scoperto oggi grazie agli amici di BDCforum e a questo articolo del sito PianetaCIclismo

_______________________________________________________________________

Fissiamo 250 Watt, la potenza di un cicloamatore medio, come valore per i nostri esempi.

Vediamo i tempi al km, per le varie pendenze, per i vari pesi.

tab. 2

Studiando attentamente la tab.2 possiamo osservare che, a parità di potenza (250 Watt), le differenze di prestazione in salita tra ciclisti di diverso peso diventano più nette con l’aumentare della pendenza infatti:

– in pianura ogni 5 kg di peso perdiamo 0,21 secondi circa al km (0,04 sec ogni kg)

– in salita al 3% ogni 5 kg di peso perdiamo 4,10 secondi al km (0,82 sec ogni kg)

– in salita al 6% ogni 5 kg di peso perdiamo 10,48 secondi al km (2,1 sec ogni kg)

– in salita al 9% ogni 5 kg di peso perdiamo 17,09 secondi al km (3,42 sec ogni kg)

– in salita al 12% ogni 5 kg di peso perdiamo 23,41 secondi al km (4,68 sec ogni kg)

– in salita al 15% ogni 5 kg di peso perdiamo 29,53 secondi al km (5,91 sec ogni kg)

Riassumiamo nella tabella seguente quanto mediamente influisce il peso alle diverse pendenze. Prendiamo come riferimento prestazioni in 1 km di salita, con differenze di peso dell’ordine di 1 – 5 e 10 kg.

tab. 3

Valutiamo sul campo queste differenze. In una salita come il Passo Giau, inserita nella Maratona delle Dolomiti, pendenza media del 9% e una lunghezza di 10 km, ogni kg in più significa perdere 3,42 secondi al km, ovvero 34,2 secondi su tutta la salita (3,42 sec * 10 km). In pratica tra due ciclisti di pari potenza ma con 20 kg di differenza il distacco sul Passo sarà di 11 minuti e 24 secondi !!! (3,42 sec * 20 kg * 10 km).

Possiamo sintetizzare queste teorie con 2 grafici:

Grafico 2: tempo al km alle varie pendenze di un ciclista con 250 watt di potenza.

Grafico 3: calo di prestazioni in secondi dovuto all’aggiunta di 1 kg sul peso complessivo ciclista-bici-abbigliamento alle varie pendenze.

The movie follows the story and an entire cycling season of “the old” Davide Rebellin, 41 years old and still fighting in the peloton after many victories and scandals, and “the young” Ignazio Moser, promising 20 years old son of cycling champion Francesco Moser.
The famous italian journalist Gianni Mura, Tour de France correspondent since 1967, helps
us to discover what cycling was and what it has become today, after doping scandals, passion, epic, richness and decadence.
Finally, a bit of madness and insane joy is brought into the movie by Didi Senft, better known as “El Diablo”, a living and metaphorical symbol of all cycling fans, with their passion and their enthusiasm.

“Ich hab Cav gepiekst!” – Didi Senft, Radsport-Fans besser bekannt als “El Diablo”, ist begeistert. Er hat seinen großen Auftritt nicht nur beim Giro, sondern auch in dem Radsport-Film “The Last Kilometer” des italienischen Dokumentar-Filmers Paolo Casalis, der am “Bicycle Film Festival 2013” in New York, Mexico City, Chicago, London, Milan, Florence und Helsinki mit großem Erfolg lief.

Nun hat Casalis die besten Szenen mit Didi Senft aus seiner Radsport-Doku zu einem siebenminütigen Kurzfilm über den Mann mit dem Dreizack zusammengeschnitten und ins Netz gestellt (siehe Link hier unten). Didi ist in Casalis’ Rad-Film “The Last Kilometer” ein Symbol für alle Radsport-Fans mit ihrer Leidenschaft und Begeisterung.
Haupt-Erzähl-Strang der Doku ist die letzte Radsport-Saison “des Alten” Davide Rebellin, 41 Jahre – und immer noch ein Kämpfer im Hauptfeld, auch nach vielen Siegen und Skandalen. Zweite Hauptfigur ist “der Junge” Ignazio Moser, vielversprechende 20 Jahre, Sohn des Radsport-Heroen Francesco Moser.

Merry Xmas!!

Film review from Canadian Cycling Magazine, Jul-Aug 2013

Film The Last Kilometer, de Paolo Casalis

The Last Kilometer explore le monde de la course cycliste professionnelle à travers les yeux de deux coureurs qui ne sont pas de la même génération : Davide Rebellin et Ignazio Moser. Ceux-ci font face à des défi s très différents : le premier a perdu la médaille d’argent gagnée aux Jeux olympiques de 2008 pour cause de dopage, et le deuxième est le fils du légendaire Francesco Moser.

Image

Pour colorer le tout, on rencontre Dietrich Senft, un inconditionnel de la chose cycliste plus connu sous le nom de Didi El Diablo, de même que Gianni Mura, un journaliste sportif italien qui a suivi tous les Tours de France depuis 1967, et dont les observations sur le cyclisme professionnel et le dopage sont parmi les plus pertinentes du film.
Sans faire de grandes révélations, ce film met en lumière la nature épuisante du cyclisme professionnel, où la déception est beaucoup plus fréquente que la victoire, et la détermination pure nécessaire à la survie.
