front derailleur doesn't shift into largest cog
Over the past year, everything worked smoothly until now. The front shifter cable for no apparent reason was making the bike unable to shift. So I removed it front the anchor bolt and discovered that wire was ceasing underneath, the bottom bracket I believe its called. After freeing the cable, I reattached it with the anchor bolt. It would shift to the middle gear but not the third. So I replaced the cable with a brand new cable only to have the same result. The shifter travels to its extreme to achieve this. Which I believe is a clue to the actual problem. Its just that I don't know precisely what that is.
Its a Falcon front derailleur.
I have tried searching for hints, but I haven't found any solution.
Thanks in advance.
