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
