Derailleur adjustment with ARI cog for Shimano and Sram cassetteOn 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 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)
