Any advantage of the XT over LX front derailleur? I am looking for more responsive shifting on my 08 stumpy (e-type).
xt costs more..... seriously its a front derailer, anything above the lx is just looking better, or is a bit lighter. Shift quality is pretty much the same, too close for all of us that are not on the pro circuit to tell a difference
speaking of which, i still have this... http://www.socaltrailriders.org/for...himano-xt-m770-e-e-type-front-derailleur.html
Performance will be the same given they're setup correctly. XT will just be lighter but more expensive.
Yes the difference is noticeable, XT will feel more precise shifting over the LX - given that you match it a similar shifter... But if you are keeping the stock shifters, (I assume X-7) then you might be just wasting your time/money on an XT FD. This is when you brace your self for the case of upgraditis. It's going to be one upgrade after another, you will find the RD needs to be more responsive too, then a better shifting cassette, then the cranks, and so on.... :lol:
Hmm...couple maintenance questions first: Have you changed out the cables? Are the chainrings straight? LX ought to be plenty responsive. I've read several reviewers pick the LX as the crispest Shimano product. Of course the shifters are clunky and cheap...
I cant say I agree with that at all. We are talking about a front Etype derailer, the Mechanics between the XT and LX for an etype are the same, one just weighs less. Def dont get XTR into the mix when talking Etypes, thats when you see something different....A flexy carbon backing. That brngs me to another question......Did it come stock with Etype? I thought all those had Speccys, built into the frame derailluers
The DMD (Direct Mount Derailleur) frames use the e-Type FD, but take out the bracket it uses to attach to the BB. That's all it is.
Finally got fed up with not being able to easily drop into granny. Bought an XT FD and what an improvement! Don't know why, but it just works. The cage looks a little narrower (ya it's the 9sp model). Maybe the old LX was just tired!
random thoughts -proper clearance of the cage to the large ring, and just enough toe in makes for snappy shifts -a derlr with a snappier spring will likely give you snappier down shifts, but rarely is this the issue. -a cable that has too much tension can prevent shifting down to the granny -so will a poorly adjust LOW limit screw -so will a poorly lubed chain and wait for it wait for it so will a worn chain I think you need the handy dandy wooden chain wear gauge on a stick j/k
Thanks for your input, but... Cage clearance was close to large ring (tried multiple adjustments) Toe not adjustable on a direct mount. Cable as loose as possible while still allowing big ring to function properly limit screw fully backed out new chain(many new chains) and lots of lubes. I think that even with the limit screw fully backed out, that the derailler was still not pulling in far enough (bad stumpy design). It is possible that the slightly different design of the XT give me just a little for inner reach (adjusstment screw still fully backed out).
I looked at the LX FD manual and it mentions that there is a "SPACER A" that you can add between the bottom bracket shell and the frame BB mount to move the crank outboard and within the drlr range. Good luck.
from a single speed site..... "changing b.b. spindle lengths or shimming bottom brackets, using spacers between the crank spider and chainrings, and whatever else you can think of to get your ring and cog to line up nicely." Conceptually, this seems applicable for drlr reach. Call Shimano and ask them for a couple of those SPACER A's mentioned in the manual above. Hope that helps.
