I was talking about this with a teammate. If you go by his wikipedia weight 86kg than that is ~5.7watts/kg. According to power profiles,if you believe in such a thing, it really isn't all that impressive. Somewhere between Cat1 and domestic pro.
Not to see it's he is not impressive more a numerical impressive vs non-impressive.
edit: it is early season...I bet his numbers go up

happened to be with his team's doctor earlier this week. don't think he weighs 86kg. i think it is common to overstate pro cyclists' weights (or quote off-season weights). e.g. horner is listed as 141--no way he was even in the 130s for the vuelta.
EDIT: remembered that they can only send one bike for the ToD...

I guess my questions are why is 5.7 watts/kg pro peleton amazing for 12 minutes ? You see guys doing that for 30+ minutes on hill climbs right? Sure at his weight it is impressive and their is something to be said for pushing those watts in the flats regardless of weight but….help me understand? yes watts/kg isn't everything in a TT but why?

Clearly, I am the only one really questioning the "amazingness" of the performance. I have a long ways to go when it comes to understanding power and I am sure his weight is a bit off from what I gathered.

w/kg isn't everything in a TT because they typically don't go uphill (very much). there's probably a VERY rough proxy to be made for some ratio between kg & CdA, but some big guys are very aero and some small ones aren't.
on the flats in a drag race, it's more about watt-for-watt.

he's probably closer to 75kg at competition.
w/kg means a lot at low speed going uphill.
but cDa does not scale up with height like mass does. Watts mean more into the wind.

At any rate, you have a successful UCI pro who just set a power record. I'm not sure what more you need to know to make that impressive.

So, Martin is complaining about the weather changes. I dunno though. Wind picked up, but also rotated more towards a tail wind for much of the course:

Wind went up from about 14mph to about 24mph during the two hours in question, but also started coming out of the NW...

First ride on my self built PT wheel today (G3, 32h, DT Swiss RR 440 Asymmetric, DT Comps).
It was interesting. I was looking at the instantaneous power and 3" power throughout the ride and I was surprised to find that they jumped around a lot (10-15W) in spite of the effort being what I thought was constant. Dead spots in the pedal stroke was my guess.
What all power numbers do you have on your primary screen?
Lots of experiments to be done! Excited.

What you're seeing is normal. Mine jumped around a lot more when I got mine.
I use three second power on all three screens on my Garmin 500.

Okay guys may be a dumb question, but today had my first experience on a Wahoo Kickr and I loved it. I don't currently have any form of power. So my question is, only have money right now for one, do I invest in a Kickr or is it more beneficial to invest in Crank based PM like SRM, Quarq or P2M. I do have Cycleops fluid trainer, but the Kickr was so smooth and on Erg mode (Sufferfest Video)you just had to pedal and not concentrate on your power as much. I spend a good amount of time year round on the trainer to get in specific workouts.

You left off PowerTap. It's hub-based, but very reliable. And, usually cheaper than the crank-based.

You can snag a Quarq for $1500. Best purchase ever(for me). I would rather be riding a junk bike and have a PowerMeter than have the latest and greatest bike and no PM.
SRM is too rich for my blood...
If you go Quarq get a Riken, don't get the older gen Cinqo.

My refurbed SRM, purchased directly from SRM, was $1600 and change, and i'd trust it over stuff made by any other company out there.

I picked up a used Quark Cinqo for $1,100 off eBay. It failed after a couple months. Quark took it back, upgraded me to Riken. No cost.

Interesting comments on DC Rainmaker's site regarding Stages and Sky.
The commenter is clearly either a Stages insider or at least sympathetic to Stages, so of course consider the source, especially for positive statements of normative effects like "sky are loving the Stages system." On the other hand, I think the point about developer responsiveness is well taken. (Regardless of whether retail customers necessarily see any difference in responsiveness between Stages and SRM, it's likely true that Stages is bending over backwards to make sure Sky has what they want, even in terms of updating firmware to meet their needs, which is something it's hard to imagine SRM doing).

Sky are loving the Stages system, they are running left side only as intended. A few riders are throwing in muddled numbers so they are using SRM on the right side to see what this could be but its a very small number. Stages respond to software requests, they are constantly updating the Firmware and I would expect to see this help out the general public too. They are also supplying large numbers of devices vs SRM who are frankly useless at customer service and only provide 2 units per rider. Training and racing is being done on stages and this morning it looked like they had changed out the riders at the TDU as well. Couldnt see the SRM’s on TV. Stages provided the head units, hence they were re sprayed… they did the work not Garmin
So fundamentally Sky build a system around the bike which meets the marginal gains idea, ok so SRM is more accurate on the face of it. However the benefits of stages outweigh the loss of the accuracy. Its lighter, it has more development going on, the company responds and works with them, they can have one on every bike, its easier for the mechanic to fit, they dont need magnets, the GPS works for mapping in the garmin so they can route remotely, the batteries last longer and are easier to change, etc, etc…
All these things add up to a better package than ultimate accuracy…
Having spent a weekend with them in Mallorca I learnt quite a lot about the way the team look at working. It actually makes a lot of sense. They don’t look at everything having a marginal gain, they look at the package providing a marginal gain.

seems like the fewer parts involved = simplicity = eventual winner. Stages is in the lead, it seems, and going by those ironman numbers, gaining ground rapidly.

I'm getting interested in Stages, but I did a mental inventory of the drivetrains on my bikes and realized I'd have to buy the entire crankset - mine are either too old or carbon.
