Okay, i get you.
Chance is, the lubricant in the Onirii pedals isn't even the source for the stickyness. I had pedals with grease, which was as sticky as glue and those were spinning just fine.
That said, i don't own the Onirii pedals, so this is just a guess.

I think they often overtorque bolts in the factories. I have a set of aliexpress pedals where one side was easy to open and the other side was impossible and it completely mangeled the bolthead.
Best practice could be to use an impact driver to unscrew stuck bolts, but i don't have one

I happen to actually like a bit of a thicker grease in pedals, because it is more water resistant and easier to clip in. I have some look carbon pedals and those spin like crazy and i hate it, although i got somewhat used to that, but i will replace the lubricant to something thicker in those soon.

Anyone tried this stem? Seems like the cleanest solution as far as I can see. It is expensive though:

I'm intereset in the 33mm wide rims.

Does anybody know how a 30mm GP5000 will sit with these 26mm inner width rims? Will it be around 33mm?
