Need help with front derailleur

I have a 2000 Trek 4500, and am in need of a new front derailleur. Was wondering if you all had suggestions for where to get them for a good price? I need to figure out what kind i need to, but i am sure i can find that through the search option.

I've gotten Deore/LX FD's on ebay for $5-10 shipped...

Looks like you need a top swing, top pull...can't tell what clamp diameter...I'd guess 31.8mm...?

Take the dérailleur off it SHOULD have the size on the inside of the clamp. If not call Trek and ask.

Very good website for comparing between various online dealers. I use it anytime I'm researching parts/prices.

You could try to measure the seat tube by "eyeballing" it... It should either be 31.8 (1 1/4") or 34.9mm (1 3/8")... Might be hard to tell when it's just 1/8" difference, though. Checking the inside of the clamp would be the best.

...there's a slight chance the your old FD is an "e type" that mounts to the bottom bracket...

It should... You'll need to remove the crankset and the bottom bracket to get the old FD off, though. (requires a crank puller and splined BB tool) And you will probably need a spacer to go in where the FD plate used to be...
