Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

NG ECO: http://ngpowermeter.power2max.com/en/

In that case, I'm definitely holding out for some bigger discounts on the S-type ones they're trying to flog off...

it is developed with a passion for excellence and with the highest focus on details.

the NGeco power meter offers you +/- 2 % precision

dynamically calibrated to guarantee a precision of +/- 1%

2% is the ngeco, 1% is for the NG

Well that's embarrassing...

What's the diff between S, NG and NGeco in layman's terms?

S type on sale already good price @danstuff says will still be cheaper. What I like is not USB but battery, no Bluetooth don't care. But does not have left/right power that NG has. I think I might need?

I'm not Eco and never will be so don't know.

Ooh, USB charging. Never thought about that but it would've allowed me to recharged the P2M during TABR. As it was I ran out of battery with a few days to go.

With all the stopping you do probably.

Dibs on yours if you sell. Compact innit?

No race, no talk.

I won't sell it. It'll just go on another bike.
I do have a few sets of Rotor cranks I should sell, but no PMs.

But does not have left/right power that NG has. I think I might need?

You won't. Absolutely pointless metric unless (according to @Dammit) you need it to get your saddle at the right height. Personally I use a tape measure or some electrical tape to do that job. And anyway, it's not a real LHS/RHS split, but some made-up number which assumes that all the power on the downstroke is due to one leg. Which it isn't. So it's a useless number that isn't even right.

Type S: 2540N battery, no bluetooth, 2% accuracy, L/R split
NG: USB charging, bluetooth, 1% accuracy, L/R split
NGeco: 2540N battery, bluetooth, 2% accuracy, L/R split by upgrade but not as standard. Other useless metrics also available by upgrade.

So this new one has Bluetooth, that's it basically? Meh.
NG was slightly tempting until I saw the price difference.

Any new crank based systems on the horizon for use with SISL2 cranks yet?

Not interested in these:

New, no. But my P2M works nicely with my SISL2 cranks.

With different chainrings, not the spiderings?

Yes. Got Praxis rings on that one, I think.

If you want to keep spidey then pedal or arm based PMs are the way, obvs.

I wouldn't expect a 'dale compatible PM to be cheap because they aren't exactly going to ship them in volume.

I have a 'dale SRM I don't need any more if you are on the look out.

Get a pair of garmin vectors. One pedal for you, one for stoker. L/R balance will give you the load split So you can see how much harder you're working at the front ;)

Heard back from 4iii: " The Omnium has a channeled back preventing it from supporting PRECISION."

Smart. Then I need an iPad attached to the back of my jersey to broadcast said data to stoker.

How bad do you want power... I got a Stages Rival arm for £210 during last years black Friday sales. You could stick one of those or the 4iiii [probably] on the S300 [https://www.bike24.com/p229035.html] which basically uses a rival arm.

Yeah, probably my first choice is to pick one of those up second hand as they are discontinued now - you aren't selling are you? (am presuming either this or the newer SRAM Stages will work with any GXP bottom bracket, Omnium or S300)
