In the four lowest gears (i.e the 28 cog end) when in both the big and small ring, loud noises can be heard coming from what appears to be near the front derailleur. I've uploaded a video of the noise here:
If I shift up from the 4th smallest gear then the noise goes away. I've checked to make show the chain isn't rubbing on the derailleur cage, and it doesn't look like it is. I've attached a picture of what it looks like when in the small ring and the 3rd lowest gear in the back. I even tried to set the low limit of the front derailleur so the cage moves in further towards the bike to see if it was in fact the cage, but that didn't seem to make the noise go away either.
is there something I'm doing wrong here?
