Hey guys. I have a few years old Cube Agree carbon fiber road bike. Now my bike has started Wobling Shimmy. I can’t ride more than 30km/h When my bike starts throwing me away. The situation is absolutely terrible. I have been in contact with Cube eu and my own importer here in Finland and with a dealership in Germany. No one wants to help me with this problem. Cube eu said buy a new bike ,,, heh heh ,,, It can't be that a bike that is a few years old has become sluggish or otherwise old. I am very disappointed that the manufacturer and not the dealer in any way want to help me with this problem.
I have come to the conclusion that do not buy a Cube Carbon Fiber Road Bike. They are toy bikes.
I cannot recommend a dealership in Germany and I do not recommend Cube Eu customer service.
Yes I buy a new road bike but I really don’t cube toy bikes.

Take it to a bike shop. Contacting an importer or dealership in another country with no more information than you gave here it will be hard to diagnose.

Hey. I suggested to the store that I send the bike and explore it. But they did not want to start cooperating. I think Cube's body is made too weak. There have been attempts to save too much weight.

If it didn't wobble for years and now it started wobbling, what changed? Do you think the frame suddenly became weaker? More likely a problem with the wheels. Did you swap a different set of wheels in? Have you checked the headset? Inspected the frame for cracks? Did you have a mechanic look at it?

30 km as in distance? Not kph as in speed.

Have you checked to see if the wheel bearings or headset bearings simply need adjustment or are worn out? If the bike didn't do this originally then as others ask, what changed?

Are there no bike shops there that can look at your bike and give you an answer?

Hey. Wobbling at speeds above 30 km / h. Bearings OK. rims OK. No structural changes were made. I suspect the body is too slack weak. Modern bicycles are made too weak. What annoys me the most is that the manufacturer and the seller do not want to cooperate in any way.

Hey. I'm not making any changes to the bike. I have not crashed or injured my bike. Bearings replaced with new ones. This is a difficult problem to solve. The cube manufacturer does not want to delve into my problem. Nor is the German seller business. And the Finnish cube importer does not want to help with the problem.

Never any wobble problem for the first several years that you rode the bike? Did the wobbling problems begin after your replaced the bearings?

Sounds like you are only wanting the manufacturer to admit they are responsible for fixing this. So if the manufacturer doesn't want to do that, then what are you wanting to do with the bike?

If I didn't want to buy another bike, then I'd take it to as many bike shops as I had to till I found one that could either fix the issue or explain to me what is happening and why it can't be fixed.

There is a phenomena known as speed wobble. At only 30 kph, I don't think this is your issue. I've only had speed wobble on very old bikes with a particular old style geometry and only at speeds over 55 kph (35 mph).

If you've found that the bearings and everything else are in good condition, then are you just wanting us to commiserate with you? I don't see any other Cube owners beating away on their keyboards to tell you they have the same issue.

If you go to "search" and enter "speed wobble" in titles only, 50 threads about this will come up. You can read about it for days.

This is by far and away the LEAST likely issue with your bike. Just sayin.....

And no, it's not too weak.
