I just got a new bike, a full suspension Felt. When the chain is on the small front sprocket and the smaller rear sprockets, it runs on the back of the front derailleur. This is with an unloaded suspension. Can this be normal or do I have the wrong front derailleur? It seems to me that the chain will saw through. Looking at another bike I have there is a lot of clearance between the chain and back side of the derailleur.
