Road tyre rubbing against inside of fork

[Weight Weenie]

Hey all

 

Went for a spin on Sunday and at about half way I started hearing a weird buzzing sound.

 

Though it may be the brakes but pulling them did not stop it.

Stopped to check the brakes and they were well aligned, QR's were tight, wheels straight.

Rode away and it started again.

 

Stopped again and started checking everything, maybe a bit of excess deraileur cable rubbing.

Finally found the issue as I saw marks on the inside of the carbon (gasp!) fork. The tyre was rubbing against the inside sides of the fork.

Spinned the wheel but nothing so as soon as I climb on the weight makes it rub somehow.

Re-inserted the wheel but didn't help.

A friendly (yes they do exist ) roadie stopped to help and said the cones on the Felt hubs were loose and tightened them by hand.

 

Now how do I sort this out ? I have cone wrenches but how do the cones just go "loose" by themselves.

Bike is not too old, has not even been in for a service yet. Being road hubs It didn't bother me that they were cheapies, as they dont take mtb hub hammering.

Wondering if they will need replacing with a better hub or will just tightening be fine ?

I'm now worried that the bearings may have been damaged by the cups not being properly adjusted...

 

Thanks,

WW.

It could be that you might have to check the http://www.winnilicious.com/wp-content/uploads/dishes.jpging.

DISHing people. DISHing

Aha ok thanks Eldron bit slow there

Good one Dangle !

 

Will do so, but after the guy "tightened" the cones by hand I rode home and it was fine so thinking that is rather the problem.

All you can do is try it. I'd suggest cleaning out the grease, check the races and balls for visible damage, re-assemble. The cones would come loose if the lock nuts weren't tight. Done well - a fraction turn here or there - you can get a cone hub to spin as beautifully as anything more expensive. And check that your forks weren't too severely damaged.

Thanks Le Turbo will give it a try.

Had a look at other wheels/hubs online and they aint cheap so this wheels must just do its job for now !

Fork I'll check in detail but it seemed to atleast be only cosmetic.

Should be a simple matter to resolve. They shouldn't work loose if they were set up right in the first place. Unless the cones or cups are damaged I wouldn't replace. Just get the bearings serviced.

Surely it will rub against the brake pad rather than the fork.

Good point, but then I don't know.

There are rubbing marks on both side of the inside of the fork so cant think of another reason that would have caused it.

I got off the bike and spun the wheel and there was no sound and I could see it was not touching so only happens when weight is applied.

Pulling brakes while riding dit not alter the sound, neither did keeping the cranks still.

[LeTurbo]

Scotty has a point. Also, if the cones were that loose that the tyre was rubbing against the forks, I can't think but that you would have felt how unsettled the bike was - and it would probably have been visible when you looked at your wheel. Marks on both sides of the fork? Your wheel would have to be severely loose - or severely buckled. Sure they weren't there before for some reason - is it a new bike?

Check your spoke tension. The wheels can still run true without a load on them but as soon as you ride the bike and shift your weight side to side you will have deflection if your spokes are loose.

Yeah got it new earlier this year, not a roadie so only really use it to train on for mtb'ing so its not doing serious K's.

Didn't spot marks there before, washed it about 3 rides back and it seemed fine.

Bike is a felt F85.

 

Havent hit any potholes so wondering if speedbumps on Klapperkop could be a reason for it ?

Tyre was pumped at 90psi, 23c size. Didnt visibly squash when I sat on the bike.

Ok will do that as well thanks !
