As I understand it, it not only measures the flywheel speed, but also the ambient temperature and humidity (along with the user entered altitude) to calculate the air density. After that, since they would know pretty well the drag properties of the fan, it would be fairly simple math to calculate the power.
So yeah...I guess that's ALL it does ;-)
BTW, I'm pretty sure it also records the data and allows you to download it as well.

I realize this misses the refinement of air pressure adjustments, but I could live without that if it saved me $250.
That's inline with what I'm hearing as well.

For those of us with crank based PM's, a speed transmitter. Wouldn't have to be accurate - just send a number so my Joule will record. Or, I guess I could dig up my HR strap from a dark corner of my gear locker where it's been for a couple of years now.

Of if you really really really want to go cheap you could get an old speed pickup from a wired bike computer, splice a miniplug on the end, and stick it into the microphone jack of a scrounged up digital recorder. Then you'd have to write a little bit of code to calculate the time interval between the blips, convert that into speed, and from there to power.

Many of you have been patiently waiting for this announcement, and we are finally able to make it:
The Power Pilot has arrived.
We are currently in the process of receiving our first production run of the Power Pilot, and we will be shipping units to customers starting Monday, 3.7.11
Our immediate priority is to begin shipment of existing pre-orders, and these will be fulfilled in the order in which they were received: the first people to pre-order the units will be the first to get them.
The supply of Power Pilots is – initially – going to be very limited. We are working to assemble a shipping timeline so that we can accurately inform customers as to when they can expect to receive their orders. We do not have this information yet. When we are able to provide ship dates, we will announce it on our Facebook page - http://www.facebook.com/lemondfitness
Thank you for your continued interest in the Power Pilot project. We’re incredibly proud of the (finally!) finished product. Thank you for giving us the time to get this done right.
It was worth it.
I placed my pre-order the day I got the e-mail from them about doing so. I had to be among the very first. I've not seen my Power Pilot yet. Getting pretty fed up about it, too. Of course, indoor riding season has been over for about a month where I am, so it doesn't really matter much now. It's just the principle of the thing.
Hi Bob,
Why don't I just re-print the response to your question on FaceBook here?
The simple answer (which also happens to be the truth,) is that your number just hasn't come up yet.
We're shipping Power Pilots out to customers in the same sequence as orders were received, and we're sending out shipping notices when orders are processed. If you haven't heard anything, it's because your order hasn't been processed, and you haven't come to the front of the queue yet.
Nobody here is particularly happy with the fact that we can't do any better on delivery timelines than to send a notice when the order is processed. We're totally beholden to the info we get from our suppliers, and they're doing exactly the same thing to us, IE, giving us info *as* they ship, with no future timelines available.
This *will* change, we're promised, but for now, we're simply stuck with very little info to pass on.

I would appreciate if you could tell us where you heard that. It's completely untrue, and it would be nice to track down the source of the rumor.
There aren't *any* pro teams that are "getting" Power Pilots at this point, and the only pro athlete that has been given a Power Pilot is Simon Whitfield, who joined our testing and evaluation team for the Power Pilot project after being one of the first to purchase a Revolution.
There are definitely "Pro" athletes who have been asking me how they can get Power Pilots, and the answer to all of them has been a simple one: they need to get on line with everyone else.

Bob, you're in the top 10 on the queue. We have another shipment of PPs coming in tomorrow, you should be receiving a shipping notice via email in the next 48 hours.
This in no way contradicts earlier info in regard to shipping timelines: we're letting people know what we can, when we can.

I would like to use the LeMond with the SRM on my bike.
My problem is that the wheel magnet SRM sensor is at the full length of the wires (and mounted on the rear chainstay) and is about 5 inches short of the outer circumference of the flywheel.
I have thought about putting a VERY powerful magnet on the flywheel but 5" is a long distance to sense.
I am looking for a simple fix - rather than something like a painted white spot on the flywheel - sensed by a photo electric cell - generating a current to a coil on the chain stay mounted SRM sensor.
Perhaps a way to conduct the magnetic field of the flywheel magnet along an iron rod extension to the SRM sensor?
Any thoughts?
Cheers,
Neal

When I'm using the SRM on the Revolution, I simply forego speed data, and manually start the session by pressing the "mode" switch. You *could* rig up a transducer of some sort to remotely trigger the SRM speed sensor, but wow... do you really need (pseudo) speed data that badly?

That's quite an interesting concept, actually. It would certainly help keep power readings consistent.

Thanks for the tip.
I did not realize I could start my SRM manually - I thought I needed the speed input to make the SRM start.
The main thing I want is watts.
That would solve my problem. Yahooooo!
I am going to test it first and then place my order for the LeMond.
I know - Read The Manual - do not assume.
From SRM V Manual:
Turning the PowerControl on and off
The PowerControl turns on when:
You press the “Mode” button
The wheel speed sensor is activated by the wheel magnet passing by the sensor (i.e.
when the wheel spins, so anytime the bike is moving)
You connect the battery charger
You connect the download cable to the PowerControl and your computer, and communication between the two begins (this only works if the serial port runs with enough current, otherwise you need to press the “Mode” button) Even if the PowerControl is on, it doesn’t receive any power data through the sensor cable until the PowerMeter is turned on. This happens when you start pedalling, (backwards or forwards). The PowerControl turns itself off when it hasn’t received any data for a 20 seconds. It stays on when the battery is charging. The PC-V display shows the time and date when it is in stand-by mode, if the screen is blank then the battery is completely dead. The PC-IV display turns off completely when the PowerControl
isn’t being used.
Cheers,
Neal
