Where can I find a history on the history of development of gearing?
Deraiulers where developed in the 30's (I think) and different systems where tried.
In particular, I was wondering how long the 5 cogs freewheel lasted.
If I'm right it was for a long time in comparrison to todays rush through 6, 7, 8, 9 & 10 cogsets.
Has the 6 - 10 cogs rush been in the last 15 years and did the 5 speed freewheel last about 25 years? Or, was the 5 cogset just another system that lasted in popularity about the same amount of time as any other system?
If I remember right when I was reading The Yellow Jersey, there was a passage about a race in which there was a discription of shifting through the 5 cogs and that book took place in the 60's (or am I off there too?)
