Rust on fork threads
Hi all,
I recently purchased a frame and fork from Cinelli; the model is the supercorsa. Due to restrictions I haven’t had the time to build it up yet, and it’s been hanging on my wall the last few months.
So I’m taking to it be assembled next week after sourcing all the parts, when I notice this on the fork threads.
fyi, I live in a very humid country near the equator, so perhaps I shouldn’t be surprised. How serious is the rusting, and what options do I have to remove it? The inside of the fork has already been rust-proofed with a rust inhibitor, but I never thought rust would form so quickly on the threads of the fork.

Use a wire brush to clean some of the rust off and then put grease on the treads and the fork tube.

That is a very common area to rust some, even on a very well cared for bike. That is extremely minor rust in the pics.

When you build up the bike, add a very minor bit of grease to the threads. You really can just place the grease at the top of the steerer tube since as you thread the headset on, it will move grease down the threaded steerer. A very small amount is all you need to ensure the threads remain in good condition for the next time you unthread the fork.

IMO, Surface rust is usually just a cosmetic issue and a very minor annoyance when undoing screws it causing your chain to bind. Just clean it off with a soft wire brush and keep a little lube, grease or oil on it to help keep it from rusting more.
If aesthetically it bothers you, there are other methods to deal with it and keep it from coming back. But in areas of salt air and high humidity, that might be a thing you have to stay on top of.
When rust gets to the point that the metal beneath it is getting pitted, then that is an actual problem, IMO.

I don’t think aesthetics are going to be an issue once it’s installed.

If you want it to look nice, tooth brush and a small amount of silver anti-seize works well.

Very minor rust. A small wire brush or even a toothbrush, and some Bar Keepers Friend which is a terrific rust remover for this kind of light rust.

Bare metal rusts. Spray some wd40 on a towel and twist the steerer tube around inside the towel for a few seconds and that will remove the superficial rust you are concerned about.
When you build up the bike, add a very minor bit of grease to the threads. You really can just place the grease at the top of the steerer tube since as you thread the headset on, it will move grease down the threaded steerer. A very small amount is all you need to ensure the threads remain in good condition for the next time you unthread the fork.

Yesh looking back I was probably worrying for nothing. Thanks though!
