Protean Gear? Sounds like a long lost unreleased album by Jimi Hendrix?

More like something from Hitch Hiker's Guide to the Galaxy!
Cheers,

Cycling was definitely posh in those days, just look at the list of customers.

From Disraeli Gears www.disraeligears.co.uk/Site/Whippet_derailleurs_page_2.html"The first of the transmission systems was an expanding chainwheel system (see UK patent 1894 # 17,908) called ‘The Protean’. It is of interest to historians of the derailleur, partly because it included an early design for a freewheel and partly because it used a sprung pulley wheel system to maintain chain tension - possibly the first instance of this in a recognisably modern form. The Protean gear system may have been used on bicycles correctly called ‘The New Whippet’, although many seemed to still call them plain Whippets". I can form a mental picture of the Victorian/Edwardian aristocracy pedaling about on one of these.  Cheers Jim |

Has this bike got suspension? Can't understand what the things connecting the down tube with the seat tube and bb are otherwise.
