rust inside pedal axle
Moderator: robbosmans
Hello, I have Shimano Ultegra PD-R8000 pedals and as you can see from the pictures I'm spotting rust inside the pedal body. It seems like it's only surface rust, as I can remove the rust by just poking around it - almost seems like it's some coating which is designed to rust and isolate the pedal axle itself from rusting.
Is this normal or is this the pedal axle itself rusting?

I have the same. At first I suspected it might have been copper anti-sieze grease but it was actually light surface rust. I've put a small dab of regular grease on it (and a few other bolts on my bike that were likewise showing early signs of rust) and it hasn't come back.
You have experianced the first stage. In the next one: https://r.tapatalk.com/shareLink/topic? ... source=app
What grease did you use? Kind of hard to grease the inside of a pedal body... goes deep in there.GeoffS wrote: ↑Tue Jun 09, 2020 11:13 pmI have the same.

Spray some WD40 in there and clean it out with a q-tip. That would probably be good enough as WD40 contains a light oil but you could put a dab of grease in there for all weather protection with another q-tip or something similarly long and skinny.
i had the same thing happen to mine - the hole doesnt go inside the pedal itself so any grease will do the job.
they probably just hollowed out the axle for weight savings, so a little surface rust wont harm the pedal, though i am dissapointed they didnt rustproof them properly.
wd40 will dissolve the rust, and some thick grease will keep it from rusting again.
