What seems to work on a bike stand may not always work when on the road, and this was exactly the case here. I thought I had trimmed the lo screw accurately enough so the chain could be on the lowest cog without hitting the spokes, but it turned out that in actual riding conditions, the musical sound of spokes hitting metal occurred. There was no other recourse in my mind except to add a spacer to move the freewheel closer to the derailleur, and it solved the problem.
- Freewheel remover for Atom freewheel
- Spacer from a Shimano Cassette ( 3 Prongs Ground Down )
- Large Adjustable Wrench
