Is is one of of only 2 known examples of this highly unconventional frame.
It was British builder.
it was built with the intention of correcting chainline issues, allowing the chainring to move from side to side, for adjusting the chainline.
The chainring is adjusted with a modified Cyclo Benelux rear derailleur that is affixed to it.
I guess Suntour also thought about this with their Asymmetrical downtube shifters, that in shifting the rear derailleur, the shifter boss adjusts the throw of the front shifter, trimming the front derailleur to adjust the chainline.
I would love to know how the Vampire Convincable shifting rides.
