Currently, my bike is Shimano 105 9-speed equipped. Most of the time, I like a gear ratio where the chain is on the largest gear on the crankset and on a large gear on the rear sprocket (english is not my first language, please correct me). This makes the chain rub on the front derailleur cage, which annoys me, in addition to prematurily wear the derailleur.
Is there a lever out there that would allow me to fine tune the position of the front derailleur? I remember that my old Deore XT left shifter allowed me to do this, if I remember well from my mountain biking memories.
