I'm building a kind of new bike and would like to put a triple or compact crankset on it.
I've still got this NOS huret derailleur set (front, rear and shifters) laying around which would match the bikes flair pretty well; but I'm worried it won't fit.
How can I calculate the maximum size difference in front and rear sprockets this derailed can handle (by looking at it's dimensions).
The derailleur model is the Huret Svelto. I'm looking into buying a crank with 34t and 48t sprockets and have a 7 speed rear cassette of 13t - 24t (but these are loose sprockets and can be changed).
What is your advice?
