I have one on my Domane but I needed to buy their sets with Rotor cranks (kept the Ultegra chainrings). I think they have now changed to the Rotor Aldhu for compatibility?
They seem to have a variety of road options, but not so much for MTB.
I’m hoping that a new generation gets released soon. Hasn’t the NG line been out for 4 years already?
And what are you expecting to be changed?

What was that cost, if you don’t mind me asking? Just bought 2 of these new and installed on wife and my MTB.
Would it be reasonable or helpful (ugly, yes) to apply some sort of glue/adhesive/epoxy preemptively to the outside of the device to just make it more robust once it’s installed? I don’t mind making things a bit ugly to prevent having to spend several hundred dollars every 16 months for replacement power meters.
Did that fix it?
Looks like it was a bigger discount than I thought. 140€ for the p2m ng eco (Shimano 4 bolt 110). 20€ shipping + the shipping of my faulty meter, so about 180€ in total. Beats having to pay 500€ for a completely new one though.
They labeled it as a P2M retrofit but in fact it was a new spider (different ant/bluetooth ID too).
Mind you, mine was still under warranty but after some discussion they wouldn’t budge. I know they have to draw a line somewhere but in my case I was 99% sure there were no external factors involved (no crashing or bumping since it’s a road bike) but hey…

I’m surprised p2m doesn’t make some sort of bash guard for mtb use. I’ve got the ngeco on my rocky vertex. It works perfectly, no spikes or anomalies ever. But, I’m terrified of bashing it on rocks or roots.
Maybe battery cover not falling off easily.

I think the bashguard transfers the load to the chainring bolts, defeating the purpose while throwing off the results. The ring should be a lot weaker than the spider, so just hit stuff.
Does your bike have a chainkeeper mount? Otherwise you can try a bash-guard adapter. https://www.amazon.com/MRP-BB-to-ISCG-05-Adapter/dp/B00MV4QC9G
I wonder if I understand this correctly, but I should be able to use this: Gravel NGeco Rotor ALDHU R 24mm w/ Cranks 2x Chainring Package – Power2Max North America
-with my Apex 1 groupset (with single chainring and compatible bb)
-Sram 1x12 groupset (with specific chainring)
-with GRX di2 front derailleur (both grx and 104 bcd standard road pacing)
-with my 2x11 5800 105 trainer bike (104 bcd standard road pacing)
What am I missing?
I just picked up an NGecgo Road Rotor power2max edition set and had my LBS install it on Shimano 105 chainrings. It’s going to replace power from my Elite Suito (direct-drive trainer), so I’ve been dual-recording my workouts to see how close they are. Thought I’d throw the power comparisons in here in case anybody’s interested:
- Capricorn (TR)
- Part of Mokelumne (TR)
- Kabati (TR)
- Wild Snow (TR)
- Senger (TR)
- McGregor -4 (TR)
- Dade +4 (TR)
P2M tracks absurdly close over 200 watts, and gets a little high (or the Suito gets little low) below that. Something something two measurements means you never know which one’s right, etc.

It’s time to change the chain.
And of coruse try to avoid cross chaining.

It’s new, and I don’t cross-chain on the trainer. Welcome to the forum
The main question for me:
Why looks much better wild snow @230W than kabati @192W?
0,8% difference vs 4% difference
Suito has an advertised accuracy of +/- 2.5%, and NGeco has +/- 2%, so it’s within the margins. Some Suito reviews suggest it gets less accurate under 200 watts. 
(I don’t see anything unexpected or wrong with those comparisons, I just thought they might be useful for anybody else considering P2M. I’d trust it over the Suito.)

Good choice!
Especially if you use the P2M on the road.
Why would a bash guard throw off power results?
I put a Wolf Tooth bash guard on mine with the p2m NGeco. Works great.
It looks like in most cases you’re putting something softer than the ring/bolts in the sandwich of the rings and power meter spider as well as introducing more things to loosen tolerances. The can put some of your power “off plane” at a yaw when you’re throwing down, which the crank PM won’t measure right. It it’s something like steel or 7075 AL and is replacing a ring on a 2x spider, it probably won’t make a difference.
