For Sheldon-a Quiz..

Hi Sheldon, I just bought a 1956 Rivetts...a British racing bike, to
display in the shop. It is really a great find but it has something
unique and unexpected in it's Simplex rear derailleur...can you guess?

Think to some of the comments I have made about 'modern' rear
deraileurs...hint, More to come.

It has a TA steel 3 arm crank, Universal sidepulls, beautiful and
amooth Campag steel center, hubs, Fiamme rims, a arm on the der, front
der. ...really cool.

Oh, let me guess! A third jockey wheel? A shopkeeper's apostrophe?
Indexing stops like the Shimano Proton system? A slant parallelogram? Is
it part of a groupo? Does it have an open pulley cage for easier chain
routing?

Sounds pretty. Photos?

I very much doubt that there's anything "unique" about the derailer,
though like most '50s derailers it will, of course, be a low-normal
design...

A Brit bike with all of those continental parts was likely a _very_ high
end machine, though I've never heard of the builder. Lucky you! Bet it
rides nicely!

Yeee-haaaa! I knew you would know...Surprised me when I shifted the
chain around.

Very smooth, works well, Not surprising since so little has actually
changed since the last 50 years.

I've got an unusual (I think) plastic Simplex rear gear in abox in the
basement somewhere...

Looks like a prestige, black delrin, chrome side-plates, stamped cage,
etcetera...except -

there's no spring in the top pivot. No place for it either, the top section
is only about 3/8" thick at the pivot bolt.

Pictures?

High-normal RapidRise configuration?

How does a three (3) arm crank work? Or is it a three (3) arm spider?

It's the spider. Three-arm used to be pretty common.
