I want to (will) use a single speed Torpedo hub
I don't think I'd compromise my frame design in order to use something which is in every way imaginable inferior to a flip-flop hub. Then again, I wouldn't even use a flip-flop hub, as being able to swap from fixed to free is one of those things which seems like a good idea but turns out in most cases just to be a way of carrying around an unused sprocket or freewheel for years.

My current tires are labeled as 37mm but they measure out to just over 35.
I certainly could fit a 40mm in there but I'm happy with the current fit and feel of what I'm rolling with, so I may just stay with that size and not have to do any finangling with the frame.
Being specifically for a slow shopper/pootler, I feel the contained nature of the hub with it's integrated brake is perfect for this application. The Torpedo from this era ('61) is of course vastly superior to what is currently available from Shimano et al.

I want to (will) use a single speed Torpedo hub and will check tonight whether I have an offset cog on it and if so, which way it’s flipped.
