Custom lots-of-titanium Brompton

It was a jacket, front light, front rack, 2 brake levers and a saddle for me.

And almost my life.

All items that individually cost more than a basic ss ring and together, a lot more than a good one.

Odd, because my SS MTB uses the standard geared middle ring, and I've never had any problems with the chain dismounting. Mind you, my track bike and fixed-gear bikes both have SS chainrings, so to err on the side of caution, a 52t Miche 135BCD chainring is winging its way to me. Means I'll have to use a 1/8" chain rather than the 3/32" one I had set aside, but that's no great hardship, although I suppose I may as well get a 1/8" sprocket for the SA 5-speed hub rather than the 3/32" one I've got at the moment.
