Cassette Wobble

So my friend brings over his new Ultegra 30-speed Windsor Knight with ShimanoWH-500 wheels to check out. Its got this slight hula wobble in the cassette. Its only noticeable when the wheel is freewheeling and the cassette is stationary. Id estimate the wobble to be between 0.020 and 0.030.

Shifting seems fine. Is this a problem?

If the shifting works well, it's more of an aesthetic problem than a technical one.

Yeah, some perfectly good freehubs do the dance. I think its caused by the freehub not being perfectly centered(concentric to the axle).

It's pretty common. Mine does the same. XT Casette on Deore hub.

Nothing to worry about

Please see this thread: Freewheel Wobble I had posted under Classic and Vintage because that's what the bike is where I noticed the problem. The equipment is a little different (casette vs freewheel), but the symptom seems to be the same.

More then pretty common. All freewheels and freehubs have a slight wobble as you describe. If not, then it doesn't freewheel.

Thanks for the replies!

I told him if he didn't like to see the wobble, then don't look.

Just Ride!

That's because it's hard to measure .030" when your micrometer is metric!
