    Wobbly cassette?

    When I had my bike on the stand a few minutes ago I noticed that when the rear wheel spins (freely, with and without pedalling), my cassette sways minutely to and fro; about 1-2mm. Is this normal? Any obvious adjustments to be made? It's Sora 8spd on my OCR3.


    I've heard enough "wtf dude obviously it's shi*t why are you even wondering go buy ultegra now" so spare it please

    I wouldn't consider it normal. It's however quite common. If your hub is still functioning properly I wouldn't worry about it.

    I am not going to tell you to run out and buy Ultegra.

    Because you already know.


    I would not worry about its performance on a bike stand up close.
    I would just ride it.

    I have seen lots of cassettes wobble, I have even seen top line stuff do it.

    It could be an illusion. The ramps on Shimano cogs can make the cassette appear to wobble...

    Your free-hub could be loose. Not a huge problem. My old Ksyriums do this (I will replace that free-hub soon, but it worked fine for many years) Like the others said, if it works fine, just ride.

    They do wobble a bit, but only if you spend time staring at it. So don't.

    It's normal. The hub body spins only when it's NOT under load, allowing the use of a mid-grade bearing with less than super-tight tolerances. Once you apply power to the pedal, that bearing stops turning and the engaging pawls center the hub body perfectly. For what it's worth, even Dura-Ace hub bodies wobble when not under load.

    Make sure your cassette and lockring are clean before you install them. If there is any grit in there, the cogs or lockring may not seat properly, causing wobble.

    The Wobbles

    I had a similar problem when I swapped my cassette to another wheel. After a lot of head scratching I found a very small ring on the old wheel that seemed to have been between the cassette and the hub. As soon as I put the ring on the wobbling stopped.

    On a side note I'm not sold on the Ultegra 10. I went from a very crisp DA 9 to the Ultegra 10 and the crisp feel is not there. I get a slightly vague shift compared to the old 9 speed.

    okay cool just one of those things that makes you ponder; I haven't seen anything about these before, so I figured I'd keep being a sponge and take in as much info as possible


    thanks for the replies

    There's this stuff called "Wobble Nought". Get a can of it and spray directly on the cogset and freehub, and it'll straighten everything right out pronto.
