    Shimano rollerbrake installation

    I never had this problem before, so I'm really puzzled: I have a Shimano rear hub with their rollerbrake attachment (I think it's the Nexus standard, or Nexave, don't recall correctly). It's the exact same attachment as on Shimano's geared hubs, eccept this isn't geared, it's for a cassette.

    So I installed the rollerbrake, but the rotating alluminum disk wobbles. I can easily push it in, but it won't stay there; after several revolutions of the wheel it goes out (towards the wheel) and wobbles. This creates a rhythmic sound that's not too disturbing, eccept I have no clue why this is happening. Braking is not affected in the slightest.

    Are you talking about the little disc that has two parts on it or fins that's for cooling? Mine has play in it until I apply the brakes, then the play goes away but it definitely isn't noisy.

    My model doesn't have fins, but I think it's exactly the same like the models with the fins - just cheaper (no cooling). Otherwise, it seems to behave the way you described; when I apply the brake, the wobbling disappears - for a second. Then it returns and it makes a periodic noise.

    For the record: I've been cycling with my new beast for a while today, and now I don't hear any noise. I guess the disk just righted itself. The braking is eccellent. I'm so thrilled now, I think I'll convert all rear brakes to rollerbrakes - where possible.
