Magene P505 PES Base Spider Powermeter

[gloscherrybomb]

Hey @gloscherrybomb -- did the magene p505 end up working for you on a tideace noah? i'm thinking about the same combo as well.

Yes...I run a tiny spacer, but that is mainly to give a bit more clearance for my 46T chainring.

can this spider be used on any other cranks?

carbon etc?
if so can you  link one?
for weight redux etc

thanks

AFAIK the PES P505 is only compatible with the cranks it comes with. But they also sell a standalone Powermeter that's compatible with other cranks:

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.

This is interesting and concerning. I was planning to get the same combo, and I did not think this could even be a problem. How's that even possible? Does the FD not travel far enough to shift?

There are even photos of passquest + Magene P505 PES, that's why it's even more shocking.

Edit: What frame and BB is this?

I tried other chainrings with my Magene power meter and just settled with Shimano chainrings.

It’s an Airwolf YFR 066 frame with a threaded ZTTO BB86 bottom bracket, but I don’t think this is the cause of the issue. I even tried fitting the Pass Quest chainrings on the Shimano crank, but it won’t shift up.

The first problem with the Magene and Pass Quest combination was that the adjustment range was insufficient, and the screw to adjust the Di2 derailleur was too short. To fix this, I made a 2mm thick plate that went under the front derailleur hanger. This allowed me to adjust it perfectly in the app, and I also tried fine-tuning it several times using the shifters. However, despite multiple adjustments, I still couldn’t get it to shift up.

Interestingly, the first time after installing the groupset, it somehow worked quite okay for a while. Since the derailleur is perfectly adjusted but still won’t shift, my guess is that the gap between the small and big chainring is somehow out of spec, or there is an issue with the tooth pattern on the chainring. With the Shimano chainring, it even shifts properly without being precisely adjusted.

It is indeed weird, because setup with Shimano cranks seems fairly common. Passquest website even advertises this setup. Would you mind posting a photo of the chainrings?
