Description
The 6202 DDU is specific to the Tacx Flux family of trainers. The DDU contact seal provides reliable protection in the warm, humid conditions typical of indoor training setups.
If your Flux has started making grinding or rumbling noises, worn bearings are almost certainly the cause. This is a direct-fit replacement.
