What is your opinion ??

Hi Hubbers

 

I have a slight problem with my bike.

It is a carbon frame.

 

Now When I put on a set of mavic ksyriums the rear wheel tyre

would rub slightly against the frame.

Now I had that wheel "dished" which sorted that out.

Now I have put the tyres from the mavics onto the

Shimano wheels and have the same problem??

Also noticed that the gap on the chainstays on either side

of the wheel is not equal.

 

What do you think the problem is??

I cant keep on "dishing " wheels.

 

Thanks

Take the frame to a/the LBS and let them put a new wheel without tyre on. See if there is anything wrong then. In the days when vertical drop-outs just came out, I saw a Cannondale that was "out" and no matter what they did to the wheels, it could not be fixed.

Are the dropouts also carbon?

 

If they are alu, one of them might be bent?

 

Perhaps post a pic to show where the tyre touches the frame (with the Shimano wheel)

Thanks for the advise

The bike had this problem from new ?

I doubt the drop out will be bent if its is "out the box"

The drop outs are alu.

I will try post a pic tommorow.

I am also going to take off the tyre and see what

the gaps look like.

Sound like the frame is out of alignment.

make a measuremnt from the dropouts to the BB on each side or to the same point on the headset, need to measure very accurate a couple of mm will make the difference

What if the frame is out of allignment?

What are the chances of a carbon frame

been out ??

Will the agent replace it? and pay for the rebuilding?

I hope so

 

I will measure it later or tommorow , with some help.

Like you said even a mm or 2 can make a big diff.

 

Thanks
