Hello,

I have a used (recumbent) bike with a Ultegra front derailleur (3 gears). I can't for the life of me seem to get it lined up properly. I've read you are supposed to have about a 2mm gap between the bottom of the cage and the top of the gear at the top; however if I do this then the back of the cage is rubbing the gear. (it's possible my large gear is too large?)

Likewise there are several bumps inside the cage to aide in shifting. Is there a diagram somewhere of where the chain should pass through in the small/medium/large gearing? Right now my middle gear passes through the tighest part of the cage (where it is dented in on both sides)

Thanks,
