tight spot on rear wheel

[stu9000]

before you say it, its not the chain (i think, anyway).

was lubing the chain today and hand rolled the rear wheel to check it.
Found a sort of dry sounding tight spot.
The wheel still turns pretty freely but...

... is it the bearings?

MOT due soon and i would not mind knowing what the problem is before it goes in

[Squiffythewombat]

does the wheel have any play it in? ie: can u wiggle it?

Well, logically it is one of three things:
1) chain and sprockets
- bent sprocket(s)
- worn and binding chain

2) brakes
- bent rotor causes binding
- stuck caliper (combined with above)

3) wheel bearings
- tough to isolate so long as chain and brake are still attached
- check for play in wheel, listen for noisy bearings

Best of luck

Have you checked your adjusters to see if they are equal?

I know they are not that accurate but they will give you a rough idea if the wheel is in line or not.

Try raming a screwdriver in between the pads and opening them up so they don't touch the disc.
If it turns freely check out the disc/calipers
If not stick a dab of grease on the chain and turn the wheel and see if goes stiff when the chain reaches the same place everytime.
BTW a stiff chain or worn sprockets is not a MOT failure
lastly if you grab the wheel top and bottom and rock the wheel side to side you should have no movement or clicking noises. That would be a worn bearing

Ok,,,
Bombed it down to Brighton today, gorgeous afternoon of A24 fast sweepers. But there is definitely something not right there. At slow speeds I can feel it, a sort of rythmic rough spot. The chain has done about 10000 miles and Im sort of expecting to need to change it, but Ive lubed it up till the bikes splattered with gunk. When i hand turn the wheel on the paddock stand there is no chain related stiff points. The chain links are not seized.

The reason im even looking for a problem in the first place is I seem to have excessive vibration through my left leg, enough to make my joints sore on a 50m run. Am i getting old or should I just stop whining and take the bike to the garage???

There is no sideways play in the rear wheel.
The sprockets look fine to me.

It might not even be the rear wheel. The vibration seems to come from the front sprocket area.

Its not that bad, but at the same time Im not sure Id find a weekend away that comfortable at the moment.

MOTs due but Ive changed jobs and am looking for a new garage. Anyone recommend anywhere in the Byfleet Woking area?

if youve done that amount of mileage on the chain get than changed first along with the sprockets as there well overdue. being as they need doing anyway if they dont sort the problem out at least you havent wasted any cash as such

[stu9000]

Yeah, I figured it made sense to change the chain. New tyres needed too. And a tune and balance is overdue.

As a general question, what things wear out on the VTR?
29000 miles on the clock.
Cam chains changed at 14000 miles.

I think this problem with the vibration has been there a while,
but its definitely getting worse.

Just had it up on the paddock stand to check a few things.

There is no play in the wheel laterally.
The wheel is on straight.
I dont think the disk is warped.

But when I turn the wheel by hand it does have tight spots. If I push it round
lightly with two fingers there is a pronounced stopping point, although its pretty easy to push on through. There are a couple of other lesser stiff points as i turn the wheel right around.

My guess is that its the rear wheel bearings.
The bike is coming up to 30000 miles.

But I wonder if the problem could be at the sprocket end?
But probably a bearing rather than chain and sprocket dont you think?

One thing, I did T bone a white van that jumped out on me a few months back. Clearly his fault and the bike got put right, but is it possible the wheel could have developed a problem over time? Seems a bit late on.

And how much chould I add on for a fix.
MOT due and new tyres, chain and sprocket already on the list.
Anyone know anywhere good in the Wimbledon to Woking, Byfleet area?

Cmon guys, solve my problems for me and make life easy

Easy to check wheel bearings

Remove rear wheel, stick finger in bearing and rotate
If its gone you'll feel it as a grindy feeling

Also, don't forget to check the one in the sprocket carrier


TBH my guess would be a couple of tight links on the chain.
Rotate forwards til you feel the tight spot, then rotate backwards a bity til the suspect link emerges from the gloom.
Check to see if it feels stiffer than the rest
