Bike fork and grease

Is this something that should be done on a regular basis or not?

Are you referring to the headset bearings? Then, yes, periodic cleaning and regreasing should be done for loose or caged balls. It's not usually needed for cartridge bearings.

You need to be a bit more specific.
Otherwise the answer is either yes or no.

Then why are you asking about something you don't understand without saying so?

Grease is primarily used as a lubricant and the only aspect of a fork in the frame that uses lube are the headset bearings. Some headset bearings are easily accessed and can be cleaned out of old lube and replenished with new. Some less so easily.

We really need more specific info- What you are asking about, what kind of bike and related parts you have (like the brand/model of headset). What tooling or supplies you have currently. Added info like what motivates you to ask/wonder about this. What kind of use/mileage/exposure to elements (rain) the bike has seen. Are there any functional issues you think you have.

To better understand how to find this all out I suggest spending an evening looking at the Park repair manual on line and also a terminology chart for bikes and their parts. Andy

Which part of the fork do you propose to grease?

People are helpful on this forum. A few have asked for more specific information and provided advice.
A fork has bearings between the steer tube and the head tube on the frame. Depending on what bike you have this may or may not need to be greased.

The wheel axle also may or may not need grease.

Sealed bearings do not need grease.
Bearings with exposed ball or roller bearings do need grease.

Well no one made suggestions they just said read a book or called me a troll and everyone else said stuff that i dont understand. I only name the name of the item as a fork. I said that to one person but i cant remember now who/m. I saw no advice. There is grease thats coming out of the fork. Is there are brand or type of fork that i should be looking for? So i can identify the fork? I get what you said about bearings but i guess unless i know more about whats inside or can see inside or open it or whatever....i sort of know what the wheel axle is maybe. Oh so since this is not exposed or visible by me then maybe it doesn't need my attention? OK confused ....but maybe its something i just dont need to be concerned with. Just like to know since issues have come up over time and i might have been able to prevent an expensive mistake or neglect if i have of known. If i had of paid attention or been able to do something about it. I have a folding ebike and i have heard others say some things wear out quicker on them. I have had ebikes for about 9 years and havent ridden a normal bike for over 20 before that because of disability. Ebikes are a real learning curve and since i have learned to do some repairs or change brake pads etc this lowers costs

Here is a diagram of bike parts and their names. https://guides.wiggle.co.uk/bike-jargon-buster-guide Take a look and try to tell us where the grease is coming from (headset, hub, etc.) There are greased bearings in the headset and hub that occasionally ooze grease and usually nothing to worry about but these parts do need maintenance every so often and you'll need to learn to disassemble/assemble them. If you can post a photo of where you found the grease it would be very helpful and we can go from there.

Where did you see the grease? That's not where more is needed.

Never mind, just wipe it off and ride.

Speaking of Greek, the word "grease" has a Greek root, and it means something like "spread it everywhere." There is no place on a bicycle where you cannot put grease. Your suspicion that it goes on the fork is correct -- it does! Think of that as a good start. Grease the entire fork, but use some economy (another Greek word, I think) to make sure you don't run out. You'll need a lot for the saddle, top and bottom. But where you will really run through a lot of grease is on the spokes and rims. Tires take grease, too, of course, but it must be applied vigorously in a circular motion with a wire brush and then heated with a paint removal gun so that it cures properly. Some people suggest putting grease between the innertubes and the tire, to reduce friction between the rubbers as they deform, but I think the performance gains here aren't worth the hassle. Maybe if you're racing a TT (time trial) or trying to set the hour record, give it a shot. Otherwise, just save the grease for everywhere else.

Good luck! There is no such thing as a dumb question. It sounds like you're actually well on your way to being a qualified shop mechanic at the average shop.
Classy response. You must be a big hit at parties.

I bet what's going on is that you have a suspension fork on your folding ebike that's leaking a little bit of oil. When you press down on your handlebars, do they spring down under pressure a bit and come back up? Then you have a suspension fork, and it's still working fine. A little oil leakage happens. The seals age a bit, and a little oil gets by. For now, just wipe it off.

Replacing the seals on a fork can be a fairly complex job -- some shops even send it out to a fork specialist.

Oh that makes sense to me .Yeah suspension sounds the right word and how you described the movement. I am so used to folding ebikes i am just not around or look at what others have much. It was such a learning curve getting into them years ago. Oh yes it springs back up. Oh good i can just wipe off...i was so unsure. I am really good at cleaning other parts of the bike that u have to on a regular basis but i just didnt know if this was something i should clean or ignore. Thanks a lot

Oh thanks yes it looks like it is this one. Says zoom on the side of the fork https://www.velostreet.com/en/produc...26-1-1-8.2219/
ok will look. I do go to a once a month community bike workshop thing so i should ask there too
