Hi, I've had the PES 515 for several months and I've never had any problems (some noise every now and then, like everyone I think...) yesterday I disassembled the PES 515 because I wanted to fit a new chain ring.....now the problem is that the double preload bolt is stuck together and by squeezing the rubber ring it no longer enters the thread of the crankset.....the only thing I can do is reassemble it without the rubber ring . What can I do?

disassemble the preload bolt with a 6 and 10mm hex. Then softly tighten it with the rubber reinstalled. This worked for me.

So, i think you need to install the rubber ring first of all. Then get the manual and follow the instruction in the reverse order i think you should be fine I hope you didn't ruin the threads

Do you have any tricks to help me do this? They seem to be welded together, I can't open them.

I have the same issue

If you have the same problem as me, I can tell you that I left the nut soaked in Svitol all night, then I placed the largest wrench (10 hex) on the floor, while with the small one (6 hex) I started to apply constant pressure for a few minutes before getting pissed off and pushing hard.

Anyway, before installing this lock ring, did you apply any grease to the thread? I applied some white grease purchased from AliExpress


Maybe this is the problem? Shouldn't you put anything on?

Did anybode found a solution against the creaking?
Reassenbled, greased etc several Times without real Changes..

Mine developed a horrific creak - turns out that one of the chainring bolts had snapped, think they are extremely soft.

Replace and retorque the bolt and see if that improves things?

Default for creaks is complete dissassembly and light touch of grease everywhere that parts meet, tends to be the cheapest and most successful outcome, even if it sometimes leaves me not knowing which bit was creaking!

Has anyone used this powermeter with a gravel build? I have a PES 515 from my previous roadbike and am planning to build up a gravel bike with either shimano or sram one by. Has anyone done that or does it not work in regards to the chainline?

A colleague of mine is using it with an Ultegra/Deore 1x12 build with a Pass Quest chainring, no issues at all.

Yes I'm using it on 1x GRX. It works. Idk if it works better or worse than normal chainline though. Should, it anything, be an improvement but that depends on where on the cassette you usually are. Also can be tight toward the chainstay depending on the bike itself and chainring size.

same here, the creaking is crazy. I already replaced the chainring-Screws, cleaned everything and greased it. No changes.
I am pretty sure it is because of the size difference between the mount and the spider.
and imo the creaking comes either from
lockring and spider is "rubbing" or
spider and mount is "rubbing".
tried 2 different type of grease already.
I would say it is a little quieter than before, but tbh i'm slowly going crazy.
So it could be imagination.

btw: Geoid PM500 seems to have the same issue.

what screws did you use out of curiosity?
i am replacing the stock shimano chainrings with aftermarket ones that use those bolts and reading reviews on the bolts many people complain the aluminium ones are too weak

i've also noticed fitting the geoid pm500 over the shimano big rings female nuts (dont laugh) takes a while of rocking the chainring back and forth, indicating poor tolerance in one of them, at least in my case

Does anyone know of stores that ship to EU that won't get me hit with surprise taxes/tolls on Magene TEO? I'm seeing some on Lordgun but they're out of 165. Did anyone order from PandaPodium or Gambacicli?
