The Return

If you have any quality issue with any component, simply return it to us for inspection (We do not pay for return shipping).

And we will issue you a replacement component or fix the original at no additional cost(You need to pay the shipping fee for the replacement component.

Replacement components will only be sent after we have received your returned component and finished an inspection to determine the cause of any problems.


The warranty does not apply:

Improper assembly, maintenance, or maintenance by an unauthorized technician.

Installation of parts or accessories or tires that are not originally intended for, or compatible with, the rims/wheels as sold.

Damage or failures caused by a crash, accidental damaged, abuse of the product, heat damage (typically caused by the wheel sitting too close to vehicle exhaust), non-compliance with manufacture specifications of usage, or any other fractious reasons.

The strongest spokes that can be used on our rims are double butted 2/1.8/2mm. Straight gauge 2mm straight gauge spokes are not allowed to be used on our rims or there is no warranty (they are too stiff to use with carbon rims).

Spokes, nipples, or wheel building issues if the wheel were NOT built by CBK.

If work is done to the wheels by a non-CBK technician, any warranty claim due to “wheel building-related issues” may be refused. If you have a potential wheel building warranty issue with a wheel built by CBK, contact us first to determine the best way to move forward. 

Normal wear and tear (Spokes, nipples, pawls, bearings, rim tape, etc.)
