(naively) thought that lowering the FD, perhaps with a wee bit of excess clearance WRT the larger chainring, would work well... funny as something that looks simple on the surface turns out to be difficult to implement
The FDER will jam against the middle ring if you lower it more than just a "bit". That's WHY the HUGE gap between the largest ring and cage.
The smallest ring is moot since you won't get past the middle.
The "slope" the FDER travels is going to remain the same no matter what you do to ring sizes.
IF it currently just clears the middle ring, how can it clear the middle ring if you lower it 4-6T more?
