Just purchased a 1993 Yo. I am looking for an old school Shimano XT front derailleur. What do I need to look for as far as size (29.4 mm?) ? Top pull?

Thank you.

29,4mm is the seatpost size, 1,25" the front derailleur size.

More stuff like this can be found on

I would go for down pull because of the pulley, but I think top pull will work too.

Yo's are 31.8mm, older pulley models are bottom pull. newer models are top pull & dont use the pulley. I didnt like the tight cable angle from the seattube braze on to the front mech using a top pull on a older pulley type frame. Might work better for you?
