Hi

My freewheel cassette this morning started to stick( pedal's kept on turning when let go) i had it on the stand, but now working, is they anyway i can lubricate it, as i believe the freewheel mechanism is in the cassette itself.

Im thinking also thinking just replace as they are not that expensive to replace it,

cheers

Either way, you will need to remove it so use a removal tool to inspect. May also depend on how worn the cogs are. Realize that this could be a cassette OR a freewheel (am guessing freewheel where the ratchet is part of the stack of cogs) but best advice is remove/inspect and then decide. Post pics if not sure.

Being lazy, I use a heavy gear oil (80W-90 is what I have) to keep my single speed freewheel running. Occasionally I get caught out in a rain storm and it sounds less happy thereafter, but the gear oil seems to keep it happy and smooth.

I slant the bike so the gear oil can stand on the side while spinning the wheel and let a few drops work into the mechanism. Pretty sure I took that suggestion off Sheldon Brown’s website.

I think best practice is to take it apart and degrease it, but as I said, I’m lazy.

I would probably just replace it, 7 speed freewheels especially these days are about as low quality as you can get so replacement is probably cheaper and easier then the time spent trying to take it apart and put it back together. Plus how worn is everything that is also a big factor in replacement.

When you say it stuck, are you talking stuck as in ghost pedaling when you let go of the pedal. Or did it stick and when you kept the pedal from turning, the chain went slack.

The former is not a issue, IMO. Though some obsess over it from the youtube videos I've seen.

If it is indeed a freewheel, then take the wheel out and place it horizontally with the freewheel up. Dribble oil into the gap between the fixed part (that doesn't move when you spin the cogs) and the smallest cog while spinning the cogs. Keep doing this until the oil coming out the bottom of the freewheel runs clear. Wipe off all the excess oil and wrap a rag or paper towel between the inside of the freewheel and the spokes. Let that drain for a few hours so you don't have oil coming out while you ride. If it's a freehub, then you need to tell us the brand and model so somebody can tell you how to take it apart and clean/lube.

Its Ghost peddling when i have in the stand, and spin the pedals by hand, when i leave go the pedals just carry on spinning,

It's only a problem if the top run of chain goes slack enough to be a potential for chain drop when you are on the bike and coasting with your feet on the pedals..

There is no such thing as a freewheel cassette. Most current 7 speed drivetrains have reverted to freewheels. For a short time when 7 speed was first introduced, there were 7 speed cassette drivetrains being produced. If your 7 speed freewheel is locking up, the most cost effective repair is to replace it unless you have almost unlimited free time and patience to repair it, and to be willing to swallow your pride when you fail and spend a very modest number of dollars for a replacement. If your bike was manufactured in the last 10 years, it almost certainly has a freewheel

If you don't want to buy the correct tool to remove, take just the wheel to a shop and pay them to remove it. If you buy the tool the best method is using a bench vise and it still sometimes can be difficult.
