Road Bike Rear Cassette Wobble

On my road bike with shimano stuff the rear cassette with all the cogs wobbles when i free wheel it.

Road bike rear cassette wobble. Each ring is a gear on your bike and the chain which connects to the pedals turns the cassette to power the bike. A discerning ear will hear an extra ta donk noise as the rider begins to pedal. A loose cassette stack causes poor shifting and increases wear to the freehub splines. Over time the teeth on the gears start to wear down making the connection to the chain weaker and costing you valuable power.

So more info and we can go from there. I ve noticed a problem with one of my rear wheels. The rear cassette is a set of concentric gear rings attached to your back wheel. Caused by not so perfect axles bearings cups and cones if this is the case not much to be done.

Essentially what happens in a speed wobble sometimes called a shimmy is that the front end of the bike oscillates moving quickly one way and then the other several times per second the video above is from a youtube user called dean magnusons. My bike isn t making noise and it isn t shifting bad just has this very visible wobble sometimes i think it s when the chain is in a bigger cog the biggest 3 are all mounted together on the cassette spider the rest are loose cogs put on one at a time.

Freewheel wobble is caused by misaligned threads on the wheel as bikemanforu shows in this tutorial. 03 09 2012 11 44 pm ratchet wrote. It is very much like this video on youtube except the bike i own is nowhere near as good or as pricey as the bike my bike is like a 150 200 bike and the wobbling on my cassette is much worse i would describe it as oscillating. 03 09 2012 09 11 pm painkiller wrote.

It is quite soothing to watch like being rocked in a cradle. Hi everyone i ve noticed when i am doing stuff such as gear indexing and my bike is up on the stand that there is a slight wobble or oscillation to the smallest two cogs in the cassette. If you look carefully when the wheel is turning at speed there just seems to be an ever so gentle movement. 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.
