  On completion of the mounting of ARI cog for XX1 cassette, follow these simple instructions to adjust the derailleur   1) Place down one of the teeth of ARI cog perpendicular to the ground (do not choose a milled tooth) 2)  Place upward one of the teeth of the upper pulley of the derailleur always  perpendicular to the ground 3)  By turning the adjusting screw of the derailleur  (photo 1)  adjust the distance between  the teeth at an height between 10 and 12mm (photo 2)
N.B.  Screw L of the rear derailleur has to be generally  unscrewed of one-half turn, this allow the chain to shift up            efficiently on the cog added because the cassette is slightly more internal than it was originally  (photo 3)

Adjustment instructions of rear derailleur with larger cogs
Instructions for the correct adjustment of rear derailleur with larger cogs   In the distance adjustment of the rear derailleur from the teeth of the larger cog you have to take extra care that the inner cage of the derailleur itself, especially during descent, does not touch the gear tooth.  In the photo 1 it is shown the inner side of the cage marked by the tooth of the cog because the adjustment WAS NOT CORRECT  In the photo 2 it is highlighted interference between the internal cage of the front derailleur and the end of the teeth of the cog; also in this case the adjustment  WAS NOT CORRECT  N.B. ATTENTION, THE INTERFERENCE OF THE DERAILLEUR CAGE WITH THE TEETH OF THE COG CAN CAUSE THE BREAKING OF THE TEETH OF THE COG
