Anyone know where there are some rider power numbers posted? I'd love to look at yesterday's time trial numbers. Thanks. :)

No idea. I wasn't aware this info was captured by very many, and also not sure how willing they would be to share it.

Found this so far:
Matthew Goss of Saxobank (originally posted on velonews.com).....putting everything aside, you gotta love the max power line:
Goss’s SRM power meter Summary Data for Stages 2-6
Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 Body Weight: 70.4 Total Time: 3:43 4:46 4:34 3:31 5:50 Stage Place: 95 76 137 146 5th Average heart rate: 127 134 138 142 140 Average cadence: 84 85 81 80 82 Average watts: 184 208 225 234 231 Max Watts: 1284 1132 992 1132 1279 Normalized power: 263 278 283 301 308 Training Stress Score: 188* 265* 292 258 409
(*based on a threshold power of 380w)

Why wouldn't they want to share it?
So much for LA's vaunted transparency!:roflmao2:

Nearly 1300 Watts max... I wonder if the tires squealed during that acceleration.
As far as riders publishing the numbers, I don't think any rider should be too hesitant to publish them since anyone who cared could get a pretty good estimate by computing based on speed, grade and weight at any given point on the course. Acceleration would be an issue too if you want to consider it at a point when the rider is accelerating. Put a camera on a rider and keep it there, and you could probably compute their power curve to within a few percentage points for the entire route. It wouldn't be easy, but it could be done if anyone cared.

IIRC the Garmin team published some in-depth numbers from last year's Giro, including from the TTT.
I'm too lazy to do a search ;), but it was discussed in the Road Racing forum.

How do you leap to LA and transparency from my post?!? Fixate much?
I doubt people would have problems with releasing data after the event, but during the event, there could be some strategic disadvantage. If I knew DiLuca had worked really hard on a given day, it could be reasoned that he would be more vulnerable to attack the following day. Similarly, if Pelizotti coasted through a stage, it might point to him preparing an attack the next day.

That is true, but I suspect that those in competition pretty much knows who was working hard on any given stage anyway... For example, everyone knows who is spending time at the front of the peloton or on the breaks versus safely behind their teammates.
But, I suspect that there is a certain aspect where any information possible is held "close to the vest" during a race just in case someone wasn't paying attention.

OK, I got bored -- err, curious. ;) Here's the thread with the ol' Slipstream power numbers: http://www.bikeforums.net/showthread.php?t=418189&highlight=millar+power
Saris also published Christian Meier's data from the 09 Amstel Gold race: http://www.saris.com/athletes/PermaLink,guid,22a7a576-4e88-4eba-896d-14d70aef3dff.aspx
Obviously part of the reason for doing this is to promote the PowerTap.

I agree, but I think it might be possible to use past data for predictive purposes as well.
Think of it this way: the DS's likely use their own team's power data extensively for strategic purposes. Publishing the data would allow other DS's to evaluate their competitors using the same talent and skills. They'd also gain data that might be tough to gather during a race -- e.g. the DS and riders might only be able to really focus on 10 guys in a field of 150; with published data, they would see what the rest of the riders are capable of and/or doing.
Mind you that I still don't think it's a big deal. Then again, I'm not a DS on a top-notch pro team... ;)
