I tried to use the Magene powermeter with 50/34 pass quest chainrings but unfortunately it won't shift onto the big chainring. I tried different adjustments for days but can't get it to work. With the original Chainrings from Shimano it will shift without any problems.

Has anyone a different working recommendation for a 12 speed Shimano ultrgra di2 which is working with the Magene Powermeter?
I would really appreciate it.

I have 11s dura Ace and changed chainrings to stone 50/34 and it works even better then 52/36 dura Ace.

I am using the version for 12s https://a.aliexpress.com/_EG6wEOU

Did anybody buy a new preload screw from Magene? I asked them via email and they charge 5 USD for it which is reasonable. But they ask for more than 20 USD for shipping to germany which i think is a little steep and doesn’t even include the import fees.

Is there any way to get it cheaper?

Maybe try geoid official store. I've bought the cranset from them and when I had a problem with preload screw I wrote to them and they've send me a new for free, just had to buy some fake auction do 4$ so AliExpress shipping was covered.

Thank you for your recommendation! Could you maybe sent a picture how it looks with the Magene pm? Thanks a lot!

Has anybody else had any calibration issues with their unit?

When I first received the power meter, every time I calibrated it, it gave a calibration value of 10-12. The power numbers it gave were reliable and as expected.

However, after a few months the battery started to run low and so I charged it back to 100%. Since then, it has given calibration values of 14-16 and has given me much lower power numbers (40-50W lower).

Thank you will try that out! I‘ve sent magene my shipping adress and now they want 5 usd for the screw and 29 usd for the shipping which is ridiculous.

I am running the Magene PES P505 Base Power Meter with Pass Quest 48/35 chainrings on a 12-speed Shimano 105 di2 setup.
Works just fine...

Could you maybe sent a linkt to the chainrings you bought? Maybe I will buy another set and try it out. Because as I said I tried them on different bikes now with the Shimano Crank and Magene Crank, so I am pretty sure there must be something off with the chainrings I got.

Seems I ordered these
https://aliexpress.com/item/1005005046221641.html
but just now I realize they are advertised as 9/10/11-speed ordinary chain in the Cycling Tribe Store.
But then I also bought these
https://aliexpress.com/item/1005006649110221.html
and they are advertised as 9/10/11/12-speed ordinary chain in the Your Bike Store.

Both in use with 12-speed Shimano Ultegra (on an Ultegra crank) and 105 (Magene PES P505 Base Power Meter), no issues with both.
