But it's not because his tires are well-aged. As to why Lance used aged tubulars, it has to do with absolute trust in your mechanic. The relationship between racer and mechanic isn't typical, and can't be defined in normal terms. The pro mechanic sells a particular brand of snake oil, along with his mechanical expertise.

There are many competent mechanics who know *what* to do, but don't have a great feel for how things interact... there's an inutitive feeling for what it takes to make something work really well, and some people have it, some don't. It's not something that can be taught. You can teach somebody how to do something well, but many will just never develop a feel for wheel truing, for example. They understand the mechanics, and can make a wheel reasonably true, but the really great mechanic will spin the wheel a couple times, note what's going on, and work a bit of magic on the spokes without even having to look at reference points on the truing stand. I imagine this is no different from work in any other field; there will be those who have a natural talent for something, and others who do things by the numbers (and get the job done, perfectly adequately, but not exceptionally). --Mike-- Chain Reaction Bicycles www.ChainReactionBicycles.com |

Dear Bill, I think that it would have been better if the mechanic who needed no truing stand or reference points had been blind and named Von Herder, but I'm influenced by "The Adventure of the Empty House": http://www.citsoft.com/holmes/return/empty.house.txt J.

On race day, the label on the tubular will match whomever the current tire sponsor is. Even if the sponsor does not make or market tubulars. |

On the other hand, George MacDonald Fraser used "The Adventure of the Empty House" in his trio of Flashman short stories, complete with voluptuous grand-daughter. S. Holmes |

(Dear) Carl you ignorant slut, If it wasn't "Dracula - Prince of Darkness" (1966), then the /best/ Hammer film was certainly: "BRIDES OF DRACULA (1960) D: Terence Fisher. CAST: Peter Cushing, David Peel, Martita Hunt, Yvonne Monlaur, Andree Melley, Freda Jackson, Mona Washbourne, Henry Oscar, Miles Malleson, Victor Brooks, Fred Johnson, Michael Ripper, Norman Pierce, Vera Cook, Marie Devereux, Harold Scott, Michael Mulcaster. For years Christopher Lee fans have tried to dismiss this film from the official canon of Hammer/Dracula films but that is impossible to do. This is a direct sequel to HORROR OF DRACULA (DRACULA) and the opening monologue makes that very clear. The is one of Hammer's most stylish vampire films making excellant use of shadow and color hues. Richly atmospheric and certainly the most erotic of the early Hammer vampire films. The recent remastering and release of the film on laserdisc and video only enhances the beauty of this film. 85 minutes." I was probably 11 or 12 when I saw this /the way God intended/ in the drive-in in 1966 or 67. Kim Horrworth's parents drove IIRC. Triple feature, of course.

It sure doesn't hurt and I admire anybody that can have that many to be able to age them..geeezzz, he must have hunderds. I wonder what he's going to do with the extras when Lance retires in about 4 weeks. I'll take 'em!!! |

This is a fallacy. A controlled test is not the only way to "know" something. Experience is another way. Experience may also superstitiously reinforce invalid beliefs, but then so can a controlled test if it includes an unaccounted-for extraneous variable or its results are misinterpreted, and at best it gives a statistical degree of confidence but not absolute certainty that the outcome of the test represents some "reality". Aging of tires seems of improbable value to me. Yet I have on occassion had a tire that didn't get used for years after I bought it that seemed to wear better without any discernable degradation in traction. I'm not convinced that this question has been settled, so when I hear that a pro team mechanic with 40 years exp. ages tires, I pay some attention to it. It makes little difference to me- I usually drink my wine soon after I buy it, and I buy a new tire because I need to use it. |

It makes little difference to me- I usually drink my wine soon >after I buy it, and I buy a new tire because I need to use it. Dear SS, When I ponder this notion of a mechanic supposedly aging tires 7 years, it occurs to me that neither traction nor wear matter much in the Tour de France. As far as I know, Armstrong and the other riders aren't testing the limits of traction much. If their tires actually lost traction when cornering, they'd probably fall. They aren't doing panic stops with the rear wheel coming off the ground, so the traction isn't likely a problem during braking. And they certainly aren't smoking the back tire and fishtailing up the Alp d'Huez, so they don't need special drag racer compounds to improve their ET's. Rainy days are probably as close as we get to a real traction test. It's fairly notorious that the Tour loafs along and takes it easy when it's wet and cold. The Tour is primarily a test of the motor, not the rubber. If there's any data showing that 7-year-cicadas--er, tires have a lower rolling resistance, that would be interesting, but it's unlikely that the difference would amount to 10 seconds in a stage. As for wear, it's hard to imagine a tire wearing out in a single day's ride on pavement, or a Tour rider who couldn't afford to replace it for the next stage. In the Discovery program, the mechanic may have explained what "performance characteristics" he thinks improve over the years, but so far there's been nothing in this thread more specific than that catch-all phrase in the original post. Does anyone know what specific "performance characteristics" (if any) that the mechanic claimed were improved by sitting in a cellar? Traction, wear, rolling resistance, fewer flats, easier mounting? And if so, how much? I suspect that what the mechanic's aging habit (if true) tells us is that Armstrong does just about as well on an old tire as a new one. Carl Fogel |

If better traction means the difference between staying upright and unsticking the sheets the morning after, i'm sure Armstrong CS will have a preference! -- --- Marten Gerritsen INFOapestaartjeM-GINEERINGpuntNL www.m-gineering.nl |

If they weren't close to the limits, they would not fall (except for when they hit gravel or water on a downhill turn). > > They aren't doing panic stops with the rear wheel coming off the ground, > so the traction isn't likely a problem during braking.

Although I doubt that aging tires is anything more than myth and lore, 10 seconds in a stage can be several places. 10 seconds per stage is 3 minutes overall, less than the winning margin of most Tours. > Does anyone know what specific "performance characteristics" (if any) > that the mechanic claimed were improved by sitting in a cellar? > Traction, wear, rolling resistance, fewer flats, easier mounting?
