I just bought my first cassette hubs ever. To my suprise it is super loud. Is there a way to quiet down these profile cassette's and still function right? I heard somewhere NOT to grease it. I dont see HOW grease would hurt it. Anyone use a certain kind of grease around the inside of the cassette with good results?

Don't grease it. IT will hurt it.

I greased my daughters Redline hub to quiet it down and it caused problems with the pawls engaging properly. So yeah, do not grease the hub to quiet it down.

Don't even worry about it. I've snuck past numerous people w/ my loud arse Chris King hub. I guarantee guys that are going to beat us are going to beat us whether our cassettes are loud or not.

Ditch them and buy a set of Stealth hubs by True Precision. Totally silent, not a click out of them. I run them on both of my bikes , 20" and 24". They also have infinite pedal position, no play in them. When you stop pedalling, you start exactly where you left off. They are less expensive than Kings and don't have the driver problems Kings have encountered.
As far as sneaking up on other riders, I've done it several times. Kind of a fun thing to do during a race.

Got my King hub off Ebay for a decent price. I've never known anyone to have a driver problem with a King hub. However, the Stealth hubs look pretty slick. $75 cheaper if you buy new, might be worth looking into. I'm of the opinion that loud hubs are not going to prevent anyone from winning a race, just the latest trend of things to worry about. Lots of good racers winning on Profiles. It's not like we race in the dark in coaster races.

I like the click of the cassette. I just goy my first of cassette's - Profiles. Love the sound. I say don't worry about it. The sound wont keep you from winning or going fast.

I totally agree, love love love the cassette sound, its almost like having your fast car loud (IMHO).

I LOVE the way that hub is talking to you! That hub is a WINNER!

I like the sound of a loud cassette too. it reminds me of kids with cards in their spokes!

For normal freewheels I use Phil Wood Tenacious oil... lay the bike on its side and spin the back wheel and drop the oil onto the inside part of the freewheel and let the spinning force drive the oil towards the edge and gravity carry it into the freewheel... keep adding the tenacious oil slowly and spinning the wheel until it quiets down... then use a paper towel to remove excess oil. This makes a normal Shimano freewheel so quiet that it can barely be heard in a quiet room...

I have not tried the tenacious oil inside a cassette hub... no idea how that would work out, but my old freewheels are so quiet that the tire noise on pavement drowns them out.

What type of oil is commonly used in the cassette pawl mechanism? Perhaps moving up to a slightly higher viscosity lubricant would make it quieter without gumming up the works... grease is just too gooey and probably keeps the spring from snapping back properly...

Well, I`ll start off by saying that John Kovachi told me that auto transmission fluid was his lube of choice on cassette hubs. It makes the hub pretty loud.

Now as far as grease goes....don`t use it. The best suggestion was posted above with the tenacious oil. It`s not so thick that it will make the pawls stick and will quiet down all but the most obnoxious hub. If you`re running the Sun Ringle` 4 stroke it`s NEVER going to be quiet.

I agree with a few of the responses above - I personally love that clicking sound, and have always associated it with the Quality of cassette hubs, particularly Profile (which I run on every bike I own). Part of it's appeal, IMO.
