Derailleur adjustment with ARI cog for Shimano and Sram cassette    On completion of the mounting of ARI cog for Shimano and Sram 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 6 and 7mm (photo 2) NB Screw H 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)
