Just changed my first chain, woo hoo. Anyways, spinning the wheels a bit, noticed a bit of wobble on my cassette. Normal?
May have the cassette installed wrong. Or maybe missing a spacer for a 10 speed cassette?
Not normal. Wobble=bad. You’ll chew up the freehub body pretty quick. It’s usually either a missing shim or spacer, or it just needs a good tightening.
It was a sram pg-1070 that came on my stock shimano r500 wheel.
Every cassette I have there is a slight play with the cassette, but not too much.
What I noticed was when I spin the wheel and let it spin, there is a slight wobble with the cassette, while its on my trainer.
I took the cassette off, cleaned it nice and shiny and tightened it real good. Still has, more like oscillating?
Check that you have the lock ring on straight. I’ve put mine on before and it’s been a little off kilter and this has been the result.
everything seemed so when i undid everything. i haven’t touched it since i got it more than a year ago.
just my trainer wheel so i guess its okay at least this much?
i know for mavic wheels it requires a spacer before the cassette goes on. the cassette itself now doesn’t seem to move. the wobble comes maybe from the freehub. will just have to ask my mechanic next time i can bring it in.
I also experienced the wobble before. The mechanic discovered that some of the ball bearings were already squared. So it was replaced then the wobble disappeared
Can you move the cassette by hand after it’s tightened, or does it only happen under drive? If you can move it by hand, does it move in and out, or back and forth?
check to see that all the spacers are there.
i’ve changed my cassette so many times, but apparently dropped the spacer the last time i did it and had to race a crit without the 19, 21, 23, and 26t on my cassette since i discovered it only 10 minutes before the start of my race. the 19 was really nice as that’s the perfect acceleration gear on some turns
The cassette doesn’t move when touching, and wobbles under drive. Specifically when I notice when the wheel it just spinning after I pull on the crank a few rotations. Maybe I’ll take a video and upload it to show.
Can you open up the R500 and check on the bearings? Will have to try that. Not sure how many miles are on this particular wheel.
I have at least 2600 miles on this wheel.
Thanks for the feedback.
Hmm…I’m sure you could check out the bearings on the R500. Though I’ve never worked on that particular wheel, I think they’re just typical cartridge bearings. You’d also want to check the freehub bearings. But if there’s no discernible grinding that’s the telltale sign of worn bearings, you might just take the wheel into a shop. There’s something funny going on.
Could be
Loose cogs on cassette barrel, add a spacer
cassette barrel has some play - this is normal on some hubs, indicative of a loose locknut or shot bearings on other hubs.
Not really wobbling - modern cassettes have ramps and teeth that are offset, when spinning this can give the illusion that the cogs are off kilter.
This isn’t my wheel, but kind of resembles what happens to my cassette:

Here is an educational thing I found on a possible reason:
as an update, brought to my lbs, and the mechanic said for this level of wheel, this was pretty much okay. asked about bearing repack and said wouldn’t be necessary.
i’ll post a video later tonight just for show, but i guess that is that with this.
