Cool!
What's that you're soaking it in?

Was thinking about doing this to a 105 crank on Facebook Marketplace.

I use oven cleaner for this, but anything with Lye should do the trick. I stripped a dropper post for this one.

Nice looking post. It's the quality of the polishing job that makes all the difference.

I used mothers metal polish. I really didnt spend much time on it - maybe 15 min? Probably needs to be disassembled and redone after a year.

Following this as well. I just picked up a cheap pair of DT Swiss hubs painted white for my winter project. I would like to strip them and polish them up. Never done anything like this before but should be fun to try.

does the lye solution attack the base metal or just the anodizing?

Should be just the anodizing.

I have heard shimano doesnt love the idea of this, maybe because of the corrosion and splitting apart issues with their road cranks. I wouldnt worry though.

Looks cool. So once you do this it tarnishes and you have to periodically re-polish?

What was Shimano doing back in the day when all the parts just looked like this to keep it from tarnishing?

I can see it not working on a dropper due to it sliding and rubbing but for a crank is there a way to clear coat it?

Heh.. does the GRX still have bonded cranks anyway? I thought Shimano used to make hollow cranks out of a single casting.. they used to make a big deal out of it, and they didn't split.

You have to dilute the oven cleaner, and even then you're risking weakening a critical component. Buyer beware.

My advancing age must be the cause of my chestnut shrinkage because there is no way I would give my bicycle a lye bath, and then expect it to safely carry my carcass anywhere worth visiting. I wouldn't trust it even for a pedal to drop a letter off at the post.

I agree that the Zukas is a nicely appointed machine!
