I use both 9170 and 9270 calipers. To me, the 9270 calipers themselves are not worth the upgrade since I don't have any rubbing on 9170. The 9270 do look nicer though.

Shimano R9200P Power Meter In-Depth Review: Astonishingly Inaccurate

https://www.dcrainmaker.com/2023/02/shi ... 7vYCazjyIU
Yikes.. Shimano sponsored teams swapping to non Shimano PMs during training? 🤦🏼‍♂️
They're probably ditching them in races too like using a non drive Stages and just going with that alone.
Stages has a new dual-sided DA unit out that has tested very well. Here is a link to GP Lama's review:

I’ve owned one. It works.

Good to hear. I don't ask much of a powermeter but basic accuracy is needed.

Good to know. Thanks. It'll likely be the way I go when I build up a DA12 bike.

Is there a possibility to run a shimano 12x drivetrain with a cassette with 10 speed cog?

Very doubtful. Why?

Because something like a 10-33 cassette with 50-34 rings would be my preferred gearing, but i don't like sram.

Aside from the issue of whether a 50X10 gear is necesssary, where are you intending to get a 10-33 10 speed cassette? As far as I can tell, there isn't one available!

Or do you mean a 10T top sprocket non-Sram cassette?

yes, i meant a 10t sprocket for 12sp. Currently i'm running 52/39 with 11-32 cassette and i can ride almost everything in the big ring. With a slightly smaller big chainring i could stay in the big ring probably 99,5% of the time. 50T with 11-32 doesn't work for me.

I have both 11T & 10T cassettes, albeit on different systems. On a gravel bike the 10T isn't that annoying because the tyres are more of an issue than the feel of the 10T. When I drop a set of slick 700C tyres into the bike it highlights just how awfully inefficient the 10T is.

Why not look at 52/36 with an 11-34? You'll gain an extra gear in the 52 as well as a slightly wider range to boot.

For those of us who are stuck with R9100P and R9200P, is there any recourse? I chatted with Canyon and they offered $50 to take it to a local Shimano tech to check out. For now, it’s just kind of a useless piece of gear on my bike and I’m running Rally pedals and dual recording.

Do you notice large discrepancies in numbers between the 2? I'm just wondering about real world use as compared to the minute analysis by DC Rainmaker, etc.

Why not just sell the Powermeter, buy a standard spider and use the Rally? The did not fix the old and my bet is that they are not going fix the new one..

I love the SW-R600 satellite shifter on my 9150 setup - though it was a 9070 generation product.

Is there anyway that this switch can be spliced into a 9250 DI2 system?
