FYI i was in contact with Magene, asking me to send a video of assembling the crank.
I think the issue is the thread for the lock ring. It seems it is not finished properly and the locking can't go further and leaves a gap, especially compared to an image found here https://www.instagram.com/p/DBvHNNtvnd0/?img_index=3

Did anyone else got a new firmware version? I updated mine yesterday after connecting it to the app.

With my chinese SKU i was never offered any updates in the last working version of Magene Utility, though i just checked with the chinese version and it offered me v0.118
Attached a machine translated version of the patchnotes.

Guess i'll update and see what happens.

Is this the same version you got?

Seems like Magene have revised the crankset on the PES P515 unit that's on display at the Shanghai bike show.

The shaping of the arms seems ever so slightly different but more importantly it now appears to attach from the drive side with a SRAM style center bolt right into the axle.

Maybe that would fix the sqeauking issue that some customers(me included) have. If thats the case i hope i can just contact them to sell me the new crankarms to fix the issue.

Interested to hear you (and others maybe?) have this issue too. I have installed and reinstalled the cranks 3 times now, cant seem to get rid of the creak. I have the p505 base version on my gravel bike and it is silent.

I run these on 3 bikes, myself 170mm and wife 2 x 165mm. Zero issues.

The creaking usually comes from other components, like chainring bolts and such. The only downside of the P505 Base is the pinch bolt, which rusts. And I have no idea what size that is, because I tried to measure it and it’s not a standard M bolt.

the last time I had creaking was from pedal spindle. I also find that the creaking from the BB area, is nearly never a BB itself.

I just got my P515 recently, which I picked up for only about CAD $260 during the June sale (without chainrings).

I'm using a 1x oval chainring and had to adjust the slope from 100% to 97% after comparing the 3-second power readings with my Saris H3+ smart trainer.

Is anyone else using the P515 with a single-chainring setup? How have you found the power accuracy, especially when compared to using a traditional round chainring?

The Magene is measuring before the drivetrain and the Saris is measuring after it. A small offset would be expected anyway, but what makes you think your trainer is more accurate?
