[Closed] Blur TRc 1x10 setup issue.

Hello to all. I had a 1x10 setup on my old heckler which I have moved onto my Blur TRc build. Up front there is no front derailleur just single chainring with chain device. The chain rubs a quite a bit on the chain device when in lower gears which i think is fairly normal but what is bugging me is when I am riding & turning the pedals & go over a bump in the trail & the rear shock compresses the chain rubs against the chain device. Can't understand why this is happening. Anybody any ideas??
