Wanted: 12t freewheel

Yes.

With the problems you are having with your BB you could possibly look at running a very small fixed sprocket at the back and a trials crankset with integral freewheel thing (do no know correct term) instead?

Caveats- if it will fit and if you can fit a larger chainring to it than is standard for trials, and also if I am not talking out of my bottom.

And so the last word is, the smallest I can have is a 16t?
Yes.

If it's a freewheel, then there's no need to worry about going downhill with your legs doing a passable impression of one of Fred Dibnah's steam engines anyway.

Ooooh, get you with the cultural reference. This thread just got upgraded.

Hippy is a tool.

Not exactly selling that one. I may head the other way to see if I can hit richmond and back. Bigger, quieter roads.
