1. Shift the derailleur to the middle front chainring. This should place the outer cage plate of the front derailleur directly above the outer chainring. 2. The gap between the teeth on the outer front chainring and the lower edge of the outer cage plate

To check the position of your front derailleur, shift it so that the derailleur arm is positioned over the outermost chainring. The derailleur "cage" (the long, curved section of the derailleur that the chain passes through) should be approximat
