I have a 2014 P3 and am going to buy a power meter. I am planning on buy not only the power meter but also crankset and chain rings. Which power meter do you recommend? I think the prices are comparable and both have similar specs. Which is more compatible and can both be installed with my existing FSA BB? Will rotor 3d+ cranks work with the quarq? How about rotor q rings, will they fit both powe meters as well? Thanks.
I would lean Quarq, because you can calibrate them yourself if need be.
Otherwise the feature sets are very similar.
Hello
Got P2M since the beginning. Never had the slighest trouble with.
You can change the battery in 5’.
Autocalibrating each second or something like that so no need to worry about weather change or climbing
Type S is just perfect
I went with Power2max because everyone I know that uses one has sent it back to Quarq for service

Both Quarq and Power2max have temperature compensation now, which can adjust for temperature changes. This is the ‘automatic calibration’ you are talking about.
That is different than an actual calibration process. Ideally calibration won’t ever be necessary but some users of power2max report getting power meters that read low to varying degrees, and power2max is not very accommodating of fixing it. They tend not to trust that the users can verify this.
If this should happen with a quarq, you can fix it yourself.
If power2max is reading this - every time you suggest that someone ride a long climb to check calibration rather than hang a weight off the pedal you are losing not just a customer, but the smart kind of customers that recommend power meters to others.

yep, same as the temp problem that they didn’t have when they first came out…
I have the new Quarq Elsa RS and it’s been working flawlessly - a pleasant change from the hell hole that was Stages.
Quarq is best- because you can update firmware at home using the Calvin app
Power2max needs to be sent in for any firmware updates

I am impressed you were able to work your way down to just those two brands.
There are a lot out there and everyone is an expert on this lately.
There are zero perfect power meters out there.
I dont care what anyone says, their experience or what their athletic and mechanical background is.
There is not a perfect one out there.
If you have narrowed it down to these two I have a system for you.
Reach into your pocket.
Take our a quarter.
Flip the quarter into the air and catch it in your hand.
Place that quarter on the back of your hand
Then if it lands on heads, buy the P2M
If its tails buy the Quarq.
You are buying a tool. Nothing more.
Just food for thought.
Is that the same way you decide between buying a framing hammer and a roofing hammer? They’re both tools…nothing more.

That would be silly.
Like your comment.
Especially since were talking about brands of pm’s.
I bet you enjoy trolling the zipps vs brand x threads too.
I do enjoy trolling, yes. I do it a lot. That’s what I am doing. Trolling.

At least next time make a valid comparison. Like a torque wrench. Hammer?
Back under your bridge troll.
If you ever happen to buy a second power meter, you will be very happy to have an option to calibrate the two to match each other. As long as P2M refuses that option, cannot seriously recommend it.
Yet people recommend powertaps that they cannot calibrate.
Edit: not directed at anyone in particular
But you can do a static torque test to know if it needs a calibration.
Never owned a P2Max, but have owned three Quarqs. The first needed servicing and required shipping to Quarq. Unknown what was wrong or what the cause but the servicing was a hundred or so.
On the third set now and have had no issues in close to a year.
There are Rotor 3d+ Quarqs out there, I owned a set (set #2) which I recently sold.

The OP asked specifically about a Quarq vs. a P2Max? Not sure why that’s really relevant.
That said, there is a much bigger sample size of PT’s out there, and among those who’ve done static calibrations the factory calibration seems to be very accurate. Plus, in my experience if the static calibration is off, they’ll repair it without much hassle or arguments that a static calibration isn’t accurate. That said, that’s main reason I’m a former PT user. Personally, I would not buy a power meter I can’t calibrate myself.
For the OP, one potential advantage to P2Max is that they claim a higher sampling rate for cadence, so that elliptical chainrings shouldn’t affect power readings. I don’t know if anyone has independently demonstrated that to be the case, but that is their claim and it would be an advantage for the OP true. The flip side is that the Quarq could be adjusted, although I’m guessing a correction factor would be cadence-dependent and not as precise.
I’ve had two Quarqs. I sent both of them back for service. They wouldn’t tell me what was wrong with them.
So what was wrong with your P2Max?
I appreciate all the thoughtful responses. I think that it seems best to go with the Power2Max. I seem to believe that Quarq has a better established reputation but more difficult to install and deal with. Power2Max seems to be more of a plug and play.
My fear with the quarq option is that it won’t work with my current bottom bracket and a new set of q rings.
