Team Ineos (Formerly the Sky thread)

[thehog]

Seems like Wiggins is just saying he decreased his cadence to improve efficiency, which is in line with the literature (Leirdal, etc). The point about resistance may be something about drivetrain efficiency (maybe indirectly something like lower cadence = more chain tension = improved drivetrain efficiency, which is reported in the literature). Surprised he didn't say anything about cog size.

FWIW, there's been some recent discussion about whether Sky is overestimating power based on the O.Symmetric rings and how the SRM estimates power (which assumes constant angular velocity). Not sure if Sky has reported being aware of this or using a fix.

Are you still rounding up 8.5m to 10m?

Still?

Still?

since you're so sore about the $1.5M rounding off I did, I'll round down the $125M you owe me to $123.5M.

But he said rolling resistance.

And there would only be increased chain tension if there was increased power. Power that magically appeared from where? Your efficiency is pretty much set in the region of 23-24%, you can't magically improve it by lowering your cadence.

By Leirdal do you mean this: http://pubget.com/paper/22092985/Ef...iciency_and_performance_in_roller_ski_skating ?

 

[Cancellator]

Your quote made the photo worthwhile.

On that note; how come Canc has the typical TT body of a rather massive *ss and upper legs, and Wiggo looks like he just got released from a three-month long hostage situtation?

You can't tell me pertinent physiology changes over a few-year period...

It's simple really, Fabian gets the bulk of his power from his quads and glutes, while Bradley gets it straight from the dope .

http://pubget.com/paper/21437606/Th...ing_technique_and_gross_efficiency_in_cycling

Within subjects, FE, DC and GE (gross efficiency) decreased as cadence increased (p < 0.001).

FE, DC and GE are not affected by body orientation or seat adjustments, indicating that these parameters and the relationship between them are robust to coordinative challenges within a range of cadence, body orientation and seat position that is used in regular cycling.

Assuming this study bears relevance on the subject at hand, we have the following:

1. higher cadence than self-selected cadence (SSC) is worse for efficiency

Unfortunately this says little about pedaling slower than SSC and its effect on efficiency, beyond the fact that they are related. The conclusion only mentions pedaling faster than SSC.

it's a known fact that you don't need to be big to push 400w+
losing weight and improving his power at the time that's hard to believe

I guess my olympic ITT picks belong here?!

1- Wiggins
2- Froome
3- Rogers

Guys, read whatever you want into it.

 

[Marco Pantani]

Hello Grampa my old friend.

4 - Eddy Boss

That would have, at least, been funny.

 

[Ney the Viking]

Lol ... 52 km/h and he does not even look nearly as tired as Panzerwagen. Farce...

 

[the sceptic]

What a monster this Wiggins is. Staying in this shape for so long. Im sure he could win the Vuelta too if he wanted

 

[Dalakhani]

"Incredible ride".

"He looks so fresh".

2 of the comments on Eurosport after he came in.

Another victory for "clean cycling". Yay.

 

[roundabout]

Don't knock the man who figured out the secrets of forward momentum.

 

[hrotha]

Disappointing ride by Rogers

 

[Dalakhani]

I wasn't watching the BBC. Did Jill Douglas speak to him the same way as she spoke to Vino?

No?

Shocker.

 

[thehog]

Yes. Amazing that he worked out that moving forward is the key.

Wiggins did around 52kmh?

Where does that sit relative to other >50min flat TTs?

Copenhagen - Martin - 51.67kmh
Vuelta 2010 - Velits - 52.36kmh
Tour 2007 - Leipheimer - 53.08kmh

 

[Mellow Velo]

Lol ... 52 km/h and he does not even look nearly as tired as Panzerwagen. Farce...

After Kristin Armstrong's time this morning, the forecast winning speed for the men's race was 53km/h.

Another farce?

I think Vuelta and Tour TTs (certainly in case of the 2007 Tour TT) were wind assisted.

Wind today?

 

[hrotha]

Maybe the forecast was wrong? Wouldn't that be more likely than absolutely everyone going too slow?

 

[Lanark]

Another victory for "clean cycling". Yay.

Don't forget the rest of the field was out of shape, everyone mispeaked for the Olympics (and the Tour as well of course).

 

[Ferminal]

Yeh Velits was definitely wind assisted too.

Not sure about the wind today. Was a loop course anyway.

 

[TheEnoculator]

To ride 52km/h for 50 mins is simply INSANE! You might as well be a freaking automobile.

 

[roundabout]

After Kristin Armstrong's time this morning, the forecast winning speed for the men's race was 53km/h.

Phinney lost about 3 seconds per km.

And he finished 4th.

Yeah, just a normal day at the office for Wigans.
