Is this normal on a bike?

spookwoman

Can anyone tell me if its normal to have a wobble in the back wheel cogs and is the plastic plate supposed to have moment as well.

Wheel rims often go out of true, particularly badly built ones. They can be re-trued by a mechanic or (if that doesn't work) replaced.

I wouldn't necessarily worry about the movement of the pie plate, maybe it's just not on straight. They don't do anything except stop a maladjusted derailleur going in to your spokes.

It's a bit difficult to see whether anything important (like the cassette sprockets) are moving oddly since the pie plate obscures it.

Bike has been out about 15 times from xmas gears been issue since day one and was told wobble is normal by shop engineer. now replacing shifter cause i cant get it int gear

irish gent

replace the wheel or have it fixed ..

spookwoman

waiting to hear back now the lie is whats annoyed me

piston

Don't see anything there to worry about.

As mentioned the pie plate is only a safety device and probably not fitted correctly which is harmless and many freewheels have a little wobble in them.

Doctor Bob

The slight wobble evident in the first five seconds of your video reminds me of the wobble I had on a bike years ago. When a mechanic investigated, he found the rear axle was bent. I might be way off, and I'm not sure what type of rear axle you have, but I'd ask him to have a look at it.

spookwoman

Just got told 1 mil allowance allowed for movement. Thats more than 1 mill movement.

TonyStark

Surely with the gears not working this is a cable tensioning thing and shouldn't really require the replacement of a shifter.

Amirani

Are any of the spokes loose?

spookwoman

No spokes loose, if gears loosened then it has problems with going into gear. Nightmare

Brian?

The pie plate is a distraction, it's wobbling all over ye shop but it's not actually causing the problem with your shifting an I don't think it's a symptom either. Take it off and bin it, it's a pointless piece of equipment.

Unknown Soldier

I can't help but notice that your wheel is attached with a couple of nuts?

Are you sure it is not at a slight angle? "Off square" or whatever it would be called.

There seems to be quite a lot of "gap" left in the wheel slot but I'd imagine your lbs can see all that?

The joys of having a shop put your bike together.

If the derailleur has the above fitting the non drive side will not fit all the way into the slot.

The movement of the freewheel looks pretty normal for that type. The rest of the video seemed to be an attempt to induce hallucinations and I couldn't tell what was happening

spookwoman

Ignore the plate and focus on cassette sprockets 1 mil min movement / wobble acceptable and the above unit I didnt see anything odd there but then again I'm not a bike person.
Not a happy bunny told bike was working links removed and ready to collect (gear issues), test it before putting in the car and gears still not working. To me there seems a hell of a lot more than 1 mill movement and when you have 2 moving objects and one goes just slightly out then its going to not work.

lescol

Could you tell us the make/model of bike or its gear shifters? How old is the bike/chain/cogs? If it was working correctly and now isn't then it's likely to be in need of adjustment with the barrel adjuster at the derailleur. If it's brand new give it back to the shop!

Looks like one of the small clips on the "pie plate" is gone and thus it is out of alignment. 2 of the clips are still in place and I suspect the 3rd has broken off. This is nothing more than a "cosmetic" issue but it does make it hard to see the cassette wobble issue. I'd get it binned off as if the gears are correctly tuned you don't need this.

From a quick google for "Cassette wobble" there appears to be a split in opinion. Some folk reckon it is normal for lower-end equipment whereas other reckon it is abnormal caused by anything from axel, spacers to hub which is getting into a dark art for me.

Try get a 2nd opinion from a well established bike shop / mechanic.

Trax tr1 mens regid , 5 months old shimano gears as I said only used few times due to illness. One thing I do know when you build something you test it before you let it out, it was not tested when bought and it was not tested today when I went to collect it.
1 of the clips is gone on the pie plate and it was making a noise. Ref wobble ok there can be a tiny tiny wobble but when its gets to a point where it could throw a gear change out then its an issue and I still think its more than 1mil.
Getting a 2nd opinion might be a problem I found out this evening that a lot of the bike shops in town don't like dealing with the bikes from this place.

I have just seen a few posts ref the model and seems they have lots of issues.

no1murray

Its is perfectly normal on a cheap ass wheel. Most cheap bikes have the wobbly freehub issue. Shouldn't cause too much of an issue, loads of tolerance.

New bike is the only solution! , how can they build , sell and warranty a bike for that sort of money?

michael196

there is an unacceptable wobble in the cassette sprockets. occurring over two or three of the sprockets

Also turn up the volume listen to the racket its making.

unacceptable. fixable. shop should be ashamed of themselves letting that go out the door.

get it back to shop, strip down the cassette and pie protector and rebuildit properly. 30 minutes max.

get the shop to mount the bike on a mechanics workbench and work the gears up and down, every single gear in the hi and low rings.

make sure no grinding sound out of it before accepting back. hard to see how the customer could have caused the poor build of the cogs onto the axle. i.e this is a clear shop build problem.

if the shop cannot repair this simple issue without fuss, stop shopping there.

dfin

Hi Spookswoman, it looks like there is some play on the free hub body which may be a little loose. Should be able to tighten this up with a 10mm Allen key if you take out the axle then re adjust gears if needed

Edit: you may want the bike shop to do this cos when you take out the axle the bearings might go all over the place and you may need to regrease

Btw the 1mm allowance mentioned above might relate to laving a clearance for the bearings which means the axles always has a slight movement

lescol

The wheel will be fitted with a freewheel and not a freehub/cassette. A look on You Tube turns up this as an example of a wobbly freewheel being replaced with a brand new wobbly freewheel, it doesn't look a lot different to the OPs video

Update they are giving me a new brand of bike and new model its a little more expensive just paying for difference. No plastic pie plates either

Result.

spookwoman

Result me ar*e1. New bike test run in carpark gears slipped, they tweeked and they slipped again further tweeking and skipped again. Refund with whinge about lost bunus! Not my fault if their bikes are crap. Went to cycle place and got one that cost a lot more but at least it works and have a bike guy to look at it and tighten it in a few weeks

Inquitus

I do note the original bike only costs £99.99 sterling, I often marvel at how stuff can be built in China, shipped half way across the world, sold in a bricks and mortar shop and still turn a profit......the wonders of capitalism, anyways, good call you are better off with whatever you have now!

spookwoman

99 or 999 still expect it to work from day 1. New one is Forme sterndale 3 and cycles like a dream, levers for the gears etc.

Type 17

Freewheel wobble like the first few seconds of the vid is due to the threads on the hub being eccentric (cheap hub). It's not an issue if it's only a visual thing, but really bad ones will cause the larger sprocket that is next to the chain to catch it as the wheel rotates, which means the gear indexing can't be set to its optimum without clattering. If this was the case, I'd want a new wheel, but not otherwise.

This may be right. I ran cheap wheels for years with screw-on freewheels, and I noticed this floating/wobbling effect with them.

Good luck with that.
