On the other hand, how many chains are linked together to span from the front chain rings to the back?
My stoker doesn't give me FD info either. I have learned to look when it is questionable.
I think it would not be hard to swap the cranks, depending on compatibility between the spindles.in terms of length.

bulgie - Please comment on the "down tube" that spans the head tube to the rear DO. It looks to me like it would provide significant stiffness compared to not having one or even like the Peugeot where it terminates at the rear BB. I have a Burley Duet which is the same design as the one shown above.

The boom tube is quite large being open at the rear allowing for cables to exit to the Atom and RD.

Burleys design look very cost effective but how good is it compared to other designs? Interesting mix of tig and brazing on the frame. The one thing I don't like is the rear BB design which is nearly unserviceable without special tools. The upside is that it shouldn't need servicing very often.

The tubes at the front BB do not have openings, allowing for water collection.
