Shouldn't it be the SRAM 3-bolt interface since it uses the Senicx PR3 crank arms?

Looks like it is a PR3 crank with a different interface, not 3-bolt.

Yep the powermeter is a magene p505, the old one and it's not compatible with other crank. I suggest to buy directly the P515 https://it.aliexpress.com/item/1005005506880823.html so you got the new version

The Magene P515 is considerably more expensive than Geoid PM500...

I am getting really happy with magene hand me down strategy with GEOID. I just bought the C606 computer rebranded cc700pro for a fraction of magene price from a year ago which was already great value.

I got it from there.
If Ali doesn't ship, try litbuy/taobao route maybe? Where about in Ireland are you, I lived in Athlone for a few years!

After normal calibration via Garmin watch works like a charm! I didn't have the chance to compare it on the trainer, but outdoors the numbers seem believable.

Just bought one of these and some goldix aero chainrings for 180 euro, great deal. Are these essentially a rebranded magene p505? For the user looking to get a link for the computer, it's on Amazon Ireland for around 80 euro

apologies derailed the thread from PM500.
Time to get thread back on track
geoid PM500 also available on Geoid store for 215euro delivered from amazon Germany

Eagerly awaiting mine, are they easy to setup? Has geoid their own app or is it magene

Ludo

Magene I believe. The prices of PM are insane right now!
