On completion of the mounting of ARI cog for XX 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)

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
Suggestions for length regulation of chain with monoring
Suggestions for the correct and efficient regulation of the chain lengh with monoring
To avoid accidental falls of the chain with the use of monoring without guidechain it is necessary that the lenght of the chain itself is perfect.
With the chain positioned on the largest rear cog, as is highlighted in the photo, the movement of the front derailleur should be
approximately between 4 and 5 mm
