• OK, thanks all. This has been really useful.

    So, just to double check, a 1/8 chain would be OK on the freewheel side if and when I want to flip back?

  • Yes: 1/8" chain is wider, so will work with 3/32" chainrings and sprockets.

    Personally, if I had 3/32" chain, chainring and freewheel I would stick with a 3/32" fixed sprocket: correcting their fuck-up is no reason to compromise your drivetrain.
