Hi everyone!

I need to buy a front derailleur for my bike and I have two models in my mind:
    Shimano Tourney Fd-tx51
    Shimano Altus M-310
    The problem is that my bike uses top-pull routing and the seller says that both models works only with bottom-pull routing but in other hand Amazon and the technical information avaible in the Shimano official page says that they work with both routing.

    My question is ¿Could be my seller derailleur different that the one that is selled in Amazon even when it has the same reference number? ¿Should I obbey my seller or the technical information from Shimano and Amazon?

    Thanks.
