Can they clean the rest of the drivetrain?
No. The CM 5.2 is strictly for the chain. You will still need a separate brush for the cassette and chainrings.
How long do the internal brushes last?
With regular home use, the brushes typically last 1–2 years before they become flared or less effective.
Is it better than manual cleaning?
It is more thorough than a brush and rag but less thorough than removing the chain for a solvent bath. It represents the “middle ground” of efficiency.
