Question

How to find out if i have a top pull pull or a bottom pull front derailleur?

Answer 1

Just take a look at it.  The shifter wire either comes from above (top pull) or it goes under the bottom bracket and comes up to the derailleur clamp from below (bottom pull).

The first image below is a standard top pull.

The second image is of a bottom pull, where the shifter wire comes from the top like a typical top pull, but which uses a converter (the black pulley) to enable the use of a bottom pull derailleur.
