shimano front derailleur replacment help needed
 

have a trek 7300 that has a bent shimano altus front derailleur needs to be replaced--I'm not good at this--finding the right part--not the install part--it is 48-38-28--8 speed. When I try to find a shimano to use, seems they don't work according to the specs. and \or don't produce the one I need anymore. can't you help me with the right model. would like to stick with shimano.

thanks

All Shimano MTB front derailleurs are compatible with the same shifters, what's the problem with the ones you find?

Guess I should have stated that I wanted to replace it with something of better quality--my opinion is that what's on there is really cheap. Seems when I was on Shimano site-- I could not get up a description of one that would work with a max 48t--if that's the right way to put it.

yes there is new alivio shifter SL-M430 with FD-M431 and should work with 48-36-26 T

would this one work even though mine is 8 spd

The cage plates "might" be a bit closer together.
That could cause chain rub a gear "sooner" when when the chain is toward the ends of the cassette.

Personally, I haven't had any trouble with Tourney>Acera FD's when properly adjusted. Just get the version for the 46/48T ring vs the 42/44T ring.
I have some gawd awful ring combos on my 2 bikes. 22-32-36 & 22-32-38.
One still has the FDER for a 48T ring. It doesn't have Dura Ace quality shifting, but it's totally "functional".

im not sure with deore m590 will work 8 speed mode smoothly also what i got information is max 44 T, shimano acera shifter ST-EF65 and FD-M360 is support 48 T with 8 speed.
