Description
This thing uses 4 disposable toothbrushes (I got 100 for 12 Euro on eBay....);
The heads of the brushes are clipped off and pushed into the main body (3) as well as the sliding part (1) - see images.
The clamp is screwed to the main body with two screws M4x16 (threads directly tapped into the plastic).
Like this it can be pushed into the bicycle chain and the slider is inserted afterwards...
... now you can turn the crank and the chain is brushed from all 4 sides!
See pictures for more details!
