First of I'd like to say hello! I'm come to this forum quite often but have only just signed up and am happy to be here. Wonderful site.
My rear cassette wobbles when my rear wheel turns. The wobble speed and the rotation speed of the wheel are synced - one revolution per wobble.
It's pretty bad. When I'm peddling hard it jumps gears back and forth quite quickly which no doubt is very unpleasant.
What is the actual issue here? The cassette? The rear hub?
Any help on a solution or what I should be looking at replacing would be great.
Thanks a bunch!

Welcome to biketutor, first I would like to know what bike you have, I have seen many a department store bikes like the ones by Pacific cycle do the same thing. Caused by not so perfect axles, bearings, cups and cones.If this is the case not much to be done. So more info and we can go from there

Hey Painkiller. Short answer is: I don't know. It's a 10 speed road bike - frame looks like a simple Peugeot road style. I have no idea what brand as it looks like it's been Frankensteined from several different bikes. It's not a new bike by the looks of it.
I just got it off a random on Craigslist so I don't really know anymore.
What you described sounds like it could be the issue as the wobble does a circular, off axis motion. To be more exact the space between the hub axle and the cassette body is larger on one side and as the wheel goes around the "larger" space moves around respectively.
aka The cassette does not appear to be parallel to the tire/chain.
Not sure if that helps at all.

PK is dead on and seems to be a problem with low end bikes. A lot of the time, if the wheel is spun an up and down motion of the cassette usually shows a bent or out of round axle. Hope all this helps.

Go to a LBS that has been around for a while. Get a used rear wheel there. I got a set (not matching, but hey) for... 20 EUR (about 25 USD?). Had to overhaul the bearings but that's not much work. Just a bit messy.
you have a freewheel, not a cassette most likely.
if you could somehow swap another freewheel to see how it acts that would help cross-check the problem to be sure if it is the hub or the freewheel....good luck sir and let us know what you come up with

Hey all. Finally got a replacement rear wheel setup and it fit perfectly and solved my issue!!
No more gear skipping or noise.
Thanks for all the help.
