a)
Pad Replacement
A pad should be replaced when its total thickness (backing plate and friction material) is less than 3mm.
b)
Derailleur adjustment (SRAM X9)
If the chain of your bicycle falls off at the largest COG/sprocket or the chain is having problems remaining on the correct
gear, you may need to adjust your derailleur. There are a multiple ways to adjust your derailleur but for a simple
adjustment on the changing of gears, follow these instructions.
Located at the shifter, the adjusting knob where the cable enters the shifter will adjust gear shifting. This knob
allows the loosening or tightening of the cable. Rotate this knob clockwise or counterclockwise until the derailleur
is properly changing gears. This is a quick fix but for a correct adjustment, the permanent adjustment should be
at the derailleur cable locking plate and fixing bolt with the shifter knob used for fine tuning.
