Crash replacement
We offer a crash replacement programme for carbon wheels. In case of accidents or heavy falls, violent shocks can damage your rim and make it impossible to use. With our Crash Replacement offer we offer you a service that allows you to replace your rim under special conditions: You get a 50 percent discount on the price of UD carbon & 3k Carbon rim, as well as the parts and the disassembly/reassembly. This offer is valid (for life) for an unlimited period of time for DUKE carbon rims and is transferable in the event of sale of the wheels to a third party.
