Cassette Wobbles?(10 posts)

Cassette Wobbles?Spinarooni
Jun 14, 2002 2:43 PM
When I put my bike up in the stand and spin the rear wheel. I can feel the cassette wobble slightly as the wheel spins. I can barely see it move if I look real close. The hub also seems to make a noise that sounds like the brakes is rubbing but I have the brake completely open so that I could take the wheel off. Wierd. Is this bad? I've had problems with my quick release letting the wheel slip out when I put alot of torque on the cranks in a low gear. like at a stop light where I sit up to go real fast and the wheel slips out ,rubs into the brakes, forcing me into a dead stop in the middle of the intersection. So I have the QR really tight so that is doesn't happen. Mavic Cosmo Wheels are POS! They go untrue in my trainer and I weigh but 172#.
Any Advice? Thanks.

This wobble issue was raised before. Do a search of the term "cassette wobble."
Cassette Wobbles, among other thingsKerry

Your cassette wobble is probably within the normal for your unit (you don't state brand or model). Take the wheel out and slowly rotate the axle with your fingers - very light pressure. You should be able to feel any roughness - the noise could be bearings or (more likely) the freehub mechanism. Wiggle the wheel at the rim when it is clamped in to see if the bearings are loose. If your QRs won't hold the wheel in the frame, get some new ones - preferably steel. Wheels that go out of true are typically under tensioned or have uneven tension. This can be remedied by a competent wheel builder.

Have you checked to make sure your cassette lock ring is tight? Sure sounds like it could be loose.

It does sound like the cassette lockring is a little loose. I had that happen to me. I spent an hour and a half trying to adjust a deraileur and a soon as I tightened the lockring, it was fine.

Bye the way Spinarooni, are you a Booker T. Fan? That was quite a Superkick Sean Michaels gave him on Raw on Monday!!!

All freehubs 'dance' a little bit in the stand. I was told (in broken English) by a group of Shimano engineers that they are designed to do this, and somehow it helps with Hyperglide shifting. How much they move is different on a case by case basis, which leads me to believe it's a tolerence issue, not a designed issue, but who am I to question the Japanese?
Well, I know one thing...Nessism

... the DuraAce freehub body wobbles less than Ultegra. This leads me to believe that bearing quality and tolerances are a factor.

The worst wobble I ever saw was on a Spinergy wheel, and per the discussions below, we know what their QC and tolerences are like...
