FD hits chainstay
I installed a Deore LX crankset (22-32-44 rings) and an LX front derailleur (FD-m571) on a 700c touring type frame (Pake C'mute). There's a big gap between the FD cage and the tops of the chainrings, so I think it should mount lower. (in the current position it requires a lot of trimming in the middle ring.) But if it goes any lower the bottom of the cage bumps into the top of the chainstay.
I picked up this deraillleur used, and i suspect these derailleurs came in 44t max and 48t max versions. How can I tell whether I have the 44t version?
On the back of the derailleur, it says it is for chainstay angles of 66-69 degrees. I pulled out the protractor and found the chainstay angle on this bike to be more like 63 degrees. This makes sense because 700c frames have more bottom bracket drop than 26" frames, and it would explain why the cage interferes with the chainstay. But the 63-66 degree front derailleurs seem hard to find. Where can I find a derailleur that will work better?
