I just finished my last attempt to tune this damned deore lx front derailer.
I have been trying to accomplish this almost impossible task for about one week.
I have read all related posts and i have visited all FD tuning pages i could find.
As i type now my hands are black and filled with lubricants and grease....
(I will get another keyboard tommorow... )
This derailleur just wont stay tuned and lately it wont shift reliably on the road except
for the middle ring.
The chain rings are not damaged, they are perfectly straight and not worn out.
The chain is in perfect condition and the rear derailleur (Deore lx) is working like a dream.
On the stand it shift well enough but not in real life.
In my last attempt i tried lowering the cage as low as i could and it is now 0.7mm above the largest chainring and rotating the cage a little bit so the front side of the cage is moved a little bit to the outside thus bringing the back of the cage inwards a little.
Basicaly i aimed for a cage that is paralel to the chainline and not the chainring at the
troublesome gear combinations.
Well now is working like a dream!!!!
The low limit screw had to be screwed in a lot so the limit could moved outwards
and the high limit screw had to be unscrewed a bit so the limit could be moved outward also.
I have already ordered a XTR M960 front derailleur but i would be very glad if someone can explain to me what i actually did because i know that this piece of junk works very well now but i dont know why!
