    lube or no lube

    Newbie wrencher here, and I've heard conflicting advice...

    When removing a cassette for cleaning, do I lube the hub body splines before putting the cassette back on?

    If so, what kind of lube?

    Thanks!

    I do. Just grease. I grease everything just to prevent corrosion. It may not help but definately wont hurt.

    I do also. It can get a bit creaky in there.

    Polylube - ( http://goo.gl/uze2Z ) or any other grease for bikes will do fine

    I don't. I've never heard a creak from there, or had any corrosion, even on my rain bike.

    I smear a thin layer of grease before I install the cassette onto the hub, mainly so I can easily remove it when the time comes. I use a bit of Phil Wood on most threads during assembly.

    Hmmm... not what I thought this thread was about...

    But seriously...

    Wow, really? Never heard of doing this. Obviously I don't. Grease of any kind really attracts dirt/grit and I figure the drivetrain is enough of a dirt magnet as-is.

    I used a wet based chain lubricant and it eventually migrates down to the freehub body. I have the cassette off for cleaning about 3 times during the year so those maintenance times the freeuhub is wiped down with a solvent leaving it squeaky clean. In the past I'd wiped the freehub with a light oil or leftover grease if I've done the wheel bearings. Because I have it off periodically, I've not encountered problems removing.

    I use a very light coat of grease.

    Always dry. Never had a problem with corroision or squeaking, and dirt/grime doesn't get gunked up.
    Done this on every bike I've ever owned. Including MTB's. Which see their share of mud, dirt, and frequent washing.

    I apply a thin coat of grease on the splines, but I'm not sure that it really matter either way.

    Thank you all for the input.

    One more question - any recommendations on a good solvent to clean a cassette? I have a great a spray on can of "Finish Line Speed bike degreaser" which works great for finishing touches, but I'm looking for more of a basic solvent to initially soak a cassette in for a bit ... any strong objections to dish soap and water to initially degrease?

    No grease on freehub body. Odorless mineral spirits will take gunk off in seconds.

    Thin coating of lithium grease on the splines before putting the cassette back on. Dish soap is not really going to do a good job cutting grime off cogs. Use mineral spirits to wipe down, if super nasty put em in a plastic jar with enough solvent to soak. I have an old plastic powdered Gatorade container with screw on lid I use for chains and other small parts. It is probably 3 inches diameter and 5 inches tall. It doesn't take much solvent to complete cover the parts. You can screw the top down and even give it a little shake to agitate.

    The bike brand citrus greasers (pedros, finish line, etc) are great but WAY overpriced. Go to Home Depot/Lowes and get a bottle of Zep citrus degreaser. It's the same thing as the bike brands but 1/3 the cost.

    There's no reason to lubricate because there's no relative movement between the cassette and body.

    But you still want to apply a film of grease because you never want parts assembled with a gap into which water can wick by capillary action. This is especially true if it involves dissimilar metals or if you ride in wet conditions.
