    I've noticed recently when coasting, when I pedal in reverse it seems like my cassette doesn't reverse direction very well. When I'm off the bike and crank the pedals, then move the pedals in reverse manually it does fine. what's the problem??

    Suspension compression effectimg chain tension (on a full suspension bike)?

    And or worn cassette teeth?

    When you're riding, the freewheel is trying to rotate forward, then when you backpedal against it, it isn't quite able to spin freely. The speed of your backpedaling isn't nearly the speed of you coasting against the freehub, so it acts differently than when you just backpedal on your own.

    It could be a sign of impending doom for your freehub if it isn't normal for it to do this. Check the chain while you're coasting and see if the upper section of the chain looks a bit sloppy.

    Also, if you have shortish chainstays, and a large 1x type cassette, backpedaling in lower gears causes issues.

    So, over a week ago got some mud on parts of the drivetrain. Cleaned up with some mild soap and sprayed a little on the cassette, I usually never do this. Could this have done it? They are Easton Haven wheels and I think they're the same for the hubs.

    It's your hobnostal defosticator... sounds like it's completely desiccated.

    I'd get a new bike, if I were you.

    Inside of the hobnostal defosticator is a set of 6 high grade steel periodontal masticators. If he can find those separately, it's probably more economical to just replace those . . . . . if you have to breakdown tool. Desiccation is a *****.

    Of course, the breakdown tool costs nearly as much as a new bike, so. . . . .
