Description
The 6205 DDU is a larger bearing found in Tacx’s Flux and Neo ranges. Its size means it handles higher loads — important in trainers that simulate steep gradients and high-wattage sprints.
As with all trainer bearings, the 6205 will wear over time. Symptoms include increased noise, vibration through the pedals, and power readings that don’t match your usual output. Replacing worn bearings restores the trainer to its original performance.
