Beloki losing rear tire... Tubular problem?
Tim McNamara wrote let it be known in
: Followed by Armstrong plowing off the road and through a field basically down the fall line, then hopping off the bike and running onto the road and remounting. Not quite with the smooth cyclo-cross style of, say, Daniele Pontoni or Adri van der Poel, but entertaining none the less. He must have been ****ting bricks! Did you catch the post-race interview with Lance? He was asked if he had done any cyclo-cross racing this year. His answer was 'Just one race, plus today makes two'. -- Curt Bousquet moc.enilnacs@PTNN Reverse for email Road biking in Southern VT and Western Mass.

Beloki losing rear tire... Tubular problem?
The video is available on OLN. Either Widows media or QT
Click http://tdf.olntv.com/ and then on the top right select Video Louis "Chris Zacho "The Wheelman"" wrote in message ... From what I heard after the fact, from Phil & Paul, was that Beloky started to slide on a soft patch of tar and panic-braked (both wheels) I was watching the 5 PM replay, so they had more info at this time. The rear tire blew and came off (very likely, especially if he was on clinchers). The bare rim dug into the tar, causing a violent reverse fishtail which hurled him over the handlebars, as he was unable to compensate in time. This is what it looked like what happened. In the slo-mo, you can see him sliding, a rear wheel slide which he is in control over. Then the tire comes off, the bike whips back and he goes head over handlebars. May you have the wind at your back. And a really low gear for the hills! Chris Chris'Z Corner "The Website for the Common Bicyclist": http://www.geocities.com/czcorner |

When reading that Beloki had rolled his rear tire, it brought to mind two things; first, Jobst's assertions that tubulars are bad in the alps due to melting glue, and second, that heavy rear braking in that situation has been discussed as a bad thing in this group. He was also using an 18mm tire. Interesting, when some using clinchers don't seem slowed at all, and he might not have so many broken bones with them. I commented: Could be, but it could also be that the rolled tub was effect, not pause. I haven't seen the video yet, but it was mentioned that he had fishtailed. This suggests to me that he may have used his rear brake when he shouldn't have. Jim Edgar wrote: Hard to say, as the footage was all from the helicopter. It was, however, a brutal crash - went down hard on his leg/hip, slid for way too long on his elbow and whip-snapped his shoulder and head down onto the pavement. Reports have him with a broken femur and elbow. How it appeared on the OLN feed this AM: Vino was about 15 seconds ahead at the crest of the hill, and was descending like a madman. Reported ambient temps were low-to-mid-90's (F). Comments had been made about the "softness" of the French roads in this region. Beloki was leading Armstrong, who had five or six riders behind him. The verbal time gap was given as 13 seconds. Vinokourov approaches the "double bowknot" set of horseshoe turns on fairly narrow roads. This will be where Beloki goes down. The screen computer shows a 10 second gap. I have since had the opportunity to watch this several times in slo-mo. It appears to me that the skid began _before_ the turn, as Beloki was trying to slow in preparation for the turn, but he had not begun to actually lean over into the sharp part of the turn. I believe this crash would not have happened if he had not used his rear brake. Lance went over the same pavement, also braking, and didn't fishtail. The moto camera was behind Vinokourov as he went through that section - you can see very shiny spots on the roadway as Vino speeds through the 90 degree left before the double bowknot. Phil states that you can see the melted spots in the roadway, and as Vino makes it through continues, "..that was a rather dodgy corner". The moto camera seems to slow and shift a bit, as the cameraman has trouble keep Vino in the frame. Do you really believe that Phil Liggett's commentary on the highlights show is done in real time? I have always assumed that he puts his script together after the event, matching the footage, which he has already seen. This isn't the first time I've seen a bit of foreshadowing in his copy. He's good at his job, so he knows how to sound surprised nonetheless. I'm very sorry that Beloki was injured, and wouldn't normally want to criticize him in a public forum like this, if it weren't for my belief that this crash offers a valuable lesson to all cyclists on the dangers of inappropriate use of the rear brake.

No way a clincher would do that of course but Lance might not be remembering everything exactly as it happened either. Yeah, it's not like events were happening quickly or anything! ;-) |

For the daily TV broadcasts I suspect this is probably the case, and CBS probably just picked up the video from the UK and edited it. He does do some overdubbing for the WCP videos, and comes here to Minnesota for those (or at least used to). |

I was watching the live coverage this morning, and Phil did indeed make that comment about the "rather dodgy corner" Vino negotiated, moments before Beloki's crash. In fact, he had commented several times on earlier descents about the treacherous nature of the road surface, due to the "bitumen melting" (although I doubt that was really a contributing factor). ~_-* ....G/ \G http://www.shastasoftware.com Developers of CycliStats - Software for Cyclists I'm very sorry that Beloki was injured, and wouldn't normally want to criticize him in a public forum like this, if it weren't for my belief that this crash offers a valuable lesson to all cyclists on the dangers of inappropriate use of the rear brake.

Beloki losing rear tire... Tubular problem?
From the photos, it appears that he was riding on clinchers, not tubulars
(based on what looks very much like a Velox rimstrip on his wheel). I'm pretty sure they're clinchers, the higher sidewalls are also clearly visible: http://www.velonews.com/images/details/4520.5461.f.jpg That is an amazing shot! Doug |

He's good at his job, so he knows how to sound surprised nonetheless. I've watched both the live and evening replay coverage of several stages and the Phil/Paul voiceover of actual race coverage is exactly the same. The sequence of intro/outro bits, Frankie Andreu interludes, etc changes, and they edit out some of the race to fit into the evening timeslot.

It might save your life: http://sheldonbrown.com/brakturn.html I'm sure you're right that he braked and locked up the rear wheel, esp. as he wasn't very far into the turn. It is possible to skid the rear on hairpins without rear braking, especially if the road is slick or loose. At least, I think I've done it, but frankly my memory is mostly of thinking "Shi-i-i-it!" I have also lost it badly in a turn due to inappropriate rear braking, but fortunately low-sided rather than high-sided. Nothing about it felt fortunate at the time. |
