  Fab. Thanks very much for the reply. Keep the updates coming, please!

  Yes, I've folded and unfolded the bike lots of times now - it gets unfolded when I'm working on it, and then folded away when I'm not. The chainline seems fine so far. I haven't fitted the chain yet, but the inner chainring is right hard against the rear triangle (which is where it needs to be) so I don't see any problems there. The only difference really is that the chainguard presses rather more firmly against the stay for the front mudguard than it does on the standard set up, so if you try to spin the pedals when the bike's folded there's much more resistance. Hardly a deal breaker though.

  Here it is in all its glory:

  

  This is a fantastic build.

  I'm late to this thread - Google brought me here because I want to put an ultratorque chainset on my brommie. I'm not sure I'll be able to do it quite as elegantly as you, but wanted to check whether there had been any issues with the chainline / other dimensions with a 52t ring on the inside.

  Have you tried folding the rear triangle? I'm currently running a vintage DuraAce setup which required minor surgery (machining off the inner studs and fitting the ring on the outside) to avoid fouling the rear triangle during folding (fitted fine except for that).

  Thanks
