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?

Pictures?

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

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?

High-normal RapidRise configuration?

Jasper

No fair. I think you peeked.

Well, I do have a Suntour arx derailer with a third jockey wheel, but
it's not especially old,

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.

Is it a ball bearing roller in the Simplex?

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.

Your Simplex Mini-Prestige likely came from a three or four
speed freewheel Peugeot folder or a similar bike.

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

You have the cycle brand correct, but not the model or freewheel size;
5-speed on a 24" racer.

Nope. Although I see I have to work on memorising exactly what is high and
what is low-normal.
