@ghettro your Jack Taylor is my dream bike. If you ever want to sell it I'll swap you the internal organ of your choice

Worn chainrings do slip, for the same reason worn cassette sprockets do. If the gears are slipping under power with a new chain and cassette, most likely causes are poor gear adjustment (sometimes caused by worn out jockey wheels or bent gear hanger), dodgy freehub body/freewheel or worn out chainring. If the slippage only occurs in one of the chainrings, that suggests it's the chainring at fault.

Seems like there's a whole lot of rust all up inside the frame tubes, and not a lot of steel left... #internetdiagnosis though, let a framebuilder have a look around it

Magura used to make hydraulic drop levers for those brakes. You could get hold of a secondhand set maybe? Nice cantis or V brakes, with a good set of levers, will be plenty powerful for tandem skiddzz (though not quite as powerful as the Mags), but without the potential magura shitstorm if the '11s go Pete Tong.

I have those on my tandem, cos they're excellent. I've got 145mm spacing, I think the bottom brackets are 122.5.
