4iii Dual Sided Power Meter Question

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

4iii Dual Sided Power Meter Question

I'm considering purchasing the 4iii Dual Sided Precision Pro Shimano 105 powermeter
Previous threads about this are a few years old, so I just wanted to see if any of you have any experience with it?
I read the DC Rainmaker review and it seems pretty positive.
I'm wondering if when the chain ring wears out, is it easy to change (without messing with the powermeter?) i.e. is the chain ring separate from the crankset in a 105 R7000?
Any other negatives about it I should consider? (this will be my first experience with a power meter)
Thanks!

What kind of crankset do you have right now? What frame/BB? Are you a weight weenie?

I went with a Power2Max, which can be reasonable (for a PM that reads full power, as opposed to the single sided), but their least expensive options are on the heavier side (if you're a ww).

I have a Shimano 105 R7000 setup.
I don’t care about weight. I’ll check out the P2M

Without changing your BB, this is the only one that's going to fit - https://power2max.cc/collections/nge...mm-with-cranks

​​​​​​Depending upon your frame, you might be able to change it your BB to a 30mm spindle format and give yourself some more options.

There is a hack where you can replace the Expedo road pedal bodies of the Assioma's with Expedo SPD bodies. GPLama has a video on it but you might have to trim the soles of the shoes. Or go the P2M route. Both are great power meters.

Personally, I'd lean towards the crank - one battery, one set of electronics to worry about. Pedals are just more finicky.

In fact, I like the Quarq Dzero/DFours in my household a lot, and CC has them on a good sale if they still have the type for your bike:

I understand. I started with mtb shoes too, then ended up converting my road bikes to road pedals and shoes. I'm not convinced it was worth it except for the Assiomas.
