    Degreaser + Cassette = Into bearings?

    A while ago I sprayed down my cassette to clean it, now, a few months later, it sounds like there is no grease on the bearings in that side. You can kind of hear, what sounds like ball bearings moving/knocking around on that side. It says I have a double sealed rear hub. Could some degreaser have gotten into the bearings?

    I've had problems with freehubs, sealed and unsealed (looseball) hubs from doing this (slow learner). Now I only degrease the cassette off the bike. And that's from a fairly mild degreaser like diluted simple green.
    I'm looking forward to regretting this.......

    So I guess I should stop riding the bike until I get this fixed.

    The bearings most likely are "sealed" but that doesn't mean they're completely impervious. The rubber seals can't be too tight or your wheels wouldn't spin as freely, so these seals can only keep most dirt and water from freely flowing in but they can't completely protect the bearing from everything. It's always possible for some degreaser to get in around the seal especially if it's sprayed at the bearing

    And you asked if it was possible, not if that is the issue.

    But any time you have a problem, it should be fixed, no matter what caused it.

    I'd say keep riding if you know for sure that it is the bearings. Most likely they are already damaged if they sound and feel gritty, so you might as well keep riding and having fun until you can replace them.

    I've ridden on shot Shimano rear hubs without any issue for years on cheap bikes. Never once ran into a problem, other than it feels horrible when you spin the wheel haha

    Great advice here.

    Why would he do something that could cause further damage, which would cost him more money, then get it looked at and fixed. If its just axle cones and bearings, its probably a $35.00 job parts & labor. Or he could continue riding it and have to have a hub replaced.

    Really good thinking.

    Not only bad advice, but shimano hubs seriously? They are so easy to service

    With luck, the cones aren't even damaged. The cost of the fix could be several minutes of the OP's time and a tube of grease, if he doesn't already have one around.

    Because running a hub that was already loose is a bad idea for a few hours? Okay. Hes already ridden it like that, so what would be the difference? Oh no, a new hub? Sadface.

    Ride the bike and worry about it later. That is always more fun, even if you have to invest a few extra bucks.

    First of all there is a big difference between knowingly choosing to do something irresponsible with your own stuff and telling other people to do irresponsible things as "good advice"

    Anyway, the potential difference in repair costs can be huge between being playing it safe to not cause further damage and purposefully running it into the ground and paying for a new hub and a wheelbuild. All it takes is a little patience
