Default Rear derailleur jockey wheel

I've noticed that when engaging the granny chainring and the largest sprocket ate the back,the top jockey wheel of the rear derailleur touches the teeth of the llarge sprocket. I don't think this is right. Anyone got any suggestion as to how to resolve this? The gears do shift well otherwise. Thanks.

A simple adjustment may fix your trouble/noise. There is a small screw where the derailleur attaches to frame. Turning this screw clockwise will increase the spring tension in the derailleur pivot and help hold it off the cassette. Depending how you use you your bike you could also consider removing a chain link or two to keep more tension on the derailleur and get better function off-road at low speeds and gear selections. You have to be careful the chain remains long enough to not interfere with using the large crank ring and lower cassette gears.
