Simple solution. Hotheads can buy a new Giro and go faster.

Spencer the Half Wit said:All this week Boardman on the ITV highlights has been in the wind tunnel showing the benefits of various improvements in aerodynamics, including drafting, bikes and helmets. What he showed was the current design of helmets with the holes produces more drag than ones with no holes to the tune of about 6 watts. Skinsuits reduce drag even more. Whilst it is not much on its own, over a 3 week tour of over 3000km it will make a significant difference.

This was a circuit. I mean circus.

Dear Wiggo said:You're making the assumption the team pursuit and individual pursuit and hour record were all done clean also.
ulrichw said:Even though I find them despicable, Marcel Kittel's accusations of Sayar are in some ways a step in the right direction.
ulrichw said:I think that's a bit of a strong statement.
The world record for the team pursuit time is 3:51 - approximately 62.34 kph. The individual pursuit record over the same distance is 4:10 - approximately 57.37 kph.
Taking the ratio of these times might be a way to approximately model the ability of a team vs. an individual in a TT.
So, using that ratio, Lemond's 34mph would translate to 36.95 mph.
As another performance figure, let's also look at Chris Boardman's hour record at 56.375 km - this was the last record attempt in a position that may approximate a modern TT position - multiplying by the ratio of team pursuit vs. individual pursuit would yield a speed of 61.26 kph (38.29 mph) - and that was over an hour.
So neither of those speeds are directly comparable and obviously there's a lot of fudging going on to get my numbers - but I think it's still tough to argue that the times set in Stage 4 represent a "circus." Take the technology advances and the potential additional benefit of starting with 9 riders vs. 4 (for the team pursuit), and you could easily see the speeds being comparable.
To me that's what "cleaner" means - performances are without a doubt closer to what could be done without doping. Are they truly "clean"? Who knows - but at least they're getting more plausible.
Hopefully the relatively smaller benefit from what doping can still be done combined with improvements in detection will move the risk/reward ratio to a point where more riders will decide it's simply not worth it.
D-Queued said:Good grief. With enough approximation, I am sure you could construct and argument that they must be approaching light speed.
1. Boardman used the Obree Superman position
2. Equating a ratio (!) obtained on (an almost) perfectly smooth surface, over a distance that can be dominated by anaerobic and neuromuscular effort to one that is ~8 times as long and must - by the nature of its length - rely on considerable aerobic effort is less than reasonable
3. Please explain again how you decided that LeMond should be 3 mph faster now? What would have changed enough to go 10% faster? What would that require - at least 30% more power at that speed? 30% more power from a guy with the highest MVO2 ever? Is this what doping would do for him?
4. There wasn't anything close to an even rotation or workload sharing
That last point should be the first point. The second last the second most important.
One guy did most of the pulling, and did that while producing at least 30% more power than the guy with the highest MVO2 ever.
He wouldn't need Boardman's superman position. He is superman.
Dave.
blackcat said:NB. At Australian Championships, in summer in Adelaide, the track gets superlatively speedy, and that is where Jack Bobridge set his WR of 410
A Tasmanian team pusuit that had an 18yo Gossie went about 3'59" in 2006. this would have been a time good enough for Olympic gold in Sydney against the Germans. actually, now i think, it would have got them silver. the Germans were under4. but not much under.
(I think. do your research and you can correct me if one wishes)
oh, if Bobridge goes 410 in Radelaide, then Taylor Phinney could go multiple seconds quicker imo. he went about 1'01" in the kilo as a 19yo going on 20. that is significantly faster than Chris Hoy went into his mid twenties. (I know hoy attempted a wr at altitude in either mexico or colombia in his mid-late twenties.)
dont see much diff in Cancellara and Taylor POhinney. if sparticus had the track souplesse, he would put out similar numbers i reckon.

Called it an amazing performance as they buried 3 teams of sprinting domestiques for 100 + kms. It was all he could do to keep from rolling his eyes at the NCBSN reporter.

Ripper said:Do you have a breakdown of how much each rider contributed?
D-Queued said:I dunno, you tell me:
“The boys did a technically good ride today,” said White. “Everyone was on the mark. I’m especially proud of Svein and Stuey [Stuart O’Grady] who both took big, long turns on the front.
All the pictures seem to have the same guy on the front.
Svein Tuft driving the pace and putting the rest of them in the hurtbox.
