Magene P505 PES Base Spider Powermeter

[kanuto]

I was able to get the pes505 base @170usd locally brand new but I dont like the crank arms. I was thinking i can put on my praxis zayante. Anyway still good price for a power meter.

Damn. Had to pay $30 for mine.

Same here, bought the P505 PES Base Spider Powermeter through the Magene Official Store on ALiExpress.
They suggested I get in contact with Service via Email, they offered the updated bolt for 5 USD and asked for 29 USD shipping to Germany with FedEx.

Has anyone tried matching P505 PES base with wolftooth 1x chainring? I'm having issues installing the bolt as there's a gap that remains after tightening the bolt.

The bolt i bought has a 6mm length, is that the right bolt to use?

Note: The chainring is wolftooth 42t 110BCD for shimano crank.

at first i thought you had the wrong bolt. but checking aliEx, 1x rings are 6mm bolts. are you sure your bolts are 6mm?
i dont have issue with passquest bolts with my pq 1x rings

theres chainring shims for the bolt for aliex as last resort

You need shorter bolts for installing this. You won't get the chainring fixed with these bolts

Looking through wolftooth website, it seems that this version "GR8" is marketed for grx crank. Rather annoying that they list this item in the normal 110 bcd listing as well. "SH" version might work, but do your own test.

For future reference. GR8 version of this chainring doesn't seem to be compatible with pes base. I ended up having to buy a normal crankset to finish my build.

Hopefully i can repurpose this powermeter to my ultegra roadbike.

did you end up getting any answers/clarity on this? i am considering the same thing.

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

I'm running it on a Tideace Noah. It looks like it is relatively bulbous in that area, so I will hold out hope!

Has anyone had any issues with loose arms that other users have reported? The new updated pre-loaded screws look promising, but I'd like to confirm with other users here.

I have the opportunity to get this for $400 CAD (incl shipping), which is very, very enticing considering how expensive powermeters are. But the loose arm reports are discouraging.

I'm pretty sure all new units ship with the updated preload screw. Mine has been problem free since I replaced the old screw with the new one.

Awesome, thanks. How long have you been using it for?

May have to place an order for one next week. 

Edit (02/08/2025): I have bought a 4iiii powermeter that was unused by someone for $220 CAD. No comment on the Magene, but I'm not passing up that sweet price I found on Marketplace!

All together, over a year. 3 months with the new preload bolt.

I have the one with the new preload screw on my roadbike and so far no issues. I've ridden more than 1000km and the crank still sits tight. I did use some loctite on the screw to be sure though. I also installed it on my gravel bike also with the new preload screw. Didn't use loctite here but it's to early to say if it holds or not as i've ridden it only two times. But i'm confident it will hold even without loctite.

10k, old screws and loctite - bomb proof

Reached out to panda podium where i bought mine after original crank bolt dislodged and eventually retraced my steps &  found it on the road.
bought threadlocker and put some on and no issues since
in the meantime PP sent out updated bolt so have a backup.
I find PP very good to deal with -289 euro delivered for PM 165mm on TT with pass quest NW 58T- find the set up great for TT leagues near me.
just need to work on the horsepowere now!
