Cheers. I have a blacked out black edition minus a couple of 'mods', so as much as I like Dura Ace, I don't think the 7800 silver will suit it. Rear tabs to clear the frame? I would've thought that you could run some spacers if the BB cups don't get in the way.

Clearance is really, really tight on the rear hinge and DS chainstay in the folded position with anything non-brompton/square taper. You can definitely get creative though...
I ended up running a MTB BB (longer thread depth but 2mm shorter cup depth) with a 2mm driveside spacer and road BB plastic centre sleeve to give me enough clearance with an Alfine chainset without screwing up the chainline and playing nicely with the 68mm shell width.
Used this post to help figure it all out

Got a Dura-Ace FC-7800 with a 53t chainring if you're keen? Came off a Brompton so has had the rear tabs ground a bit to clear the frame, etc.
