I have an 03 XT bottom pull/top swing front der that has a hard time dropping into the small ring when the chain is in the larger rear cogs & under a reasonable load. Under a soft load it drops fine. By reasonable, I mean the force needed when going up a hill but not jamming on it either. Under load the plate has shifted but the chain stays in the middle ring.
The outside plate has an inner indent on the chain side that doesn't extend the entire plate length so that the pushing of the chain from middle to small has a wider inside width & it is further away from the chain. I see the indent as being the problem.
It seems to be adjusted fine where the plate is a bit above the teeth on the big ring & the low stop when in low-low combo is 1/8-1/4", anymore looks to ask for trouble.
