Anyone use a Rotor 2in Power Meter?

[trener1]

I am wondering if anyone uses the Rotor 2in Power Meter?.
I can't seem to find many reviews out there.

I am looking for a PM for my gravel bike and they seem to have some options for smaller chaingrings, looking for some real world feedback in general.
Also I have a P2Max on 2 of my road bikes and was wondering if the numbers would match up pretty closely?.

I don't have a Rotor 2InPower meter, but I do have a Power2Max NGEco Gravel Rotor compatible power meter. This power meter has the 110mm/80mm BCD of GRX gravel cranks, and fits on Rotor Aldhu cranks:

This power meter works pretty much the same as the Power2Max power meter I use on my road bike. As far as I can tell it i just as accurate as other Power2Max power meters. This power meter spider uses 110mm/80mm BCD Shimano GRX gravel chainrings, which are also made by a a number of other chainring makers. The standard chainring sizes for this BCD are 48/31 and 46/30, but chainrings in some other sizes are available as well (for example, TA Specialites makes 48,46 & 44 outer chainrings, and 32, 31,30 & 28 inner chainrings)

I have a 2in power on one bike and a quarq on another. It's a bit subjective but they both give similar output on my training routes. I'm a fan of rotor and run their cranks on CX bikes. I got the 2in one since I can swap them out easily with a normal rotor 3D when racing. Power data is great for training, but pretty worthless in a cx race imho.

Only drawback. While the rechargeable battery is nice, the charging cable is ridiculously short.

I have the 2in power pm with anldhu arms. Works fine, readout is fine, approx 300 hours of charge. I have the 110x4 with rotor rings and the aero spider. Looks cool. Would recommend.

However, I really don’t like the preload style. Coming from Shimano 9000/6800 this was kind of fiddly.

Agree on the charging cable but honestly I’ve gone 1/2 season without charging.
