Description
The 6002 DDU is a rubber contact-sealed bearing used across multiple trainer brands and models. The DDU seal provides better protection against dust and debris than shielded variants, making it well suited to the demands of indoor training.
Worn bearings are the number one cause of excessive trainer noise and degraded power accuracy. Replacing them is the single most effective maintenance you can do.
