I need to fit a new front mech on my Trek 7.3
I have been given a Deore conventional swing mech. The old one is a top swing one - not sure of the spec. Are top swing and botton swing ones interchangeable?
Assuming we are not talking about top/bottom pull mechs, I am unsure why cable routing is going to be an issue. Generally top swings are used so that the clamp can be positioned a little lower to allow more room for bottle cages etc. on the downtube.
