Normally gravity and vibration does the job for me
After some really muddy races last year, i hat to hose it, but normally i let the mud fall off from itself. When i need to take the muni in the trunk of my car, i just use an old shoe brush to brush the dry mud off.
I use a water hose and brush or rag to clean mine. As long as you don’t spray water directly at the bearings, it will be fine. Getting the bearings wet is fine though. Spraying directly at them with high pressure could push water, dirt and grit past the bearing seals. The seals will hold up fine otherwise.
I just let the mud dry, then scrub it off with a brush (something like a nail brush), then if it needs it, I’ll wipe it down with a rag and some WD40 for a bit of shine. Bearings might get repacked every now and then but not too often as they don’t really need it
About 2 times a year I take the whole thing apart… actually we have a “party” in the basement and we all get to work – have to keep track of the parts with so many disassembled at the same time. Even have a 12" in there for the 4 year old.
I tend to find surface rust on the outside of the bearings and it begins to show on the bearing caps. The screws that hold on the bear caps show surface rust as well.
I get out the “000” steel wool and get everything cleaned up…but it comes back even with things like WD-40, Lithium grease, and Silicone lubricant to help prevent it.
Is this typical?
I see videos of people riding in the ocean, mud, puddles… we’ve never done that, but seem to have this rust issue.
Yep humidity and dust get between the bearing and the clamps and it takes ages to dry. Since the bearing doesn’t have a protective coat, it rusts (surface rust phew!). One thing you can do is put a thin layer of grease on the bearing before you put the uni back together, that will protect it. A bit.
