Type 2 Derailleur "Knocking"
This is a cross-post from the drivetrain thread, but I am posting here to see if anybody can shed any light on the issue.
SRAM type 2 derailleur issues - Page 2 - Mtbr Forums
In summary; the derailleur (X9) worked very well for the first 6-7 rides. However, just yesterday I noticed that at the same point in the suspension travel (~50% of the rear travel) there was a loud knock. Initially I didn't pin it on the derailleur, but after careful checking of everything else, I engaged the cam lock and the knocking could no longer be felt/heard when the rear shock is compressed. When riding along, this knock can be felt through the crank arms and pedals. It is very annoying and loud.
Anybody else having this issue? It seems like a few guys are (see link above). Is this just a warranty replacement issue, or can it be fixed?
