I put my rear wheel back on and now my chain hits my derailleur guide. The chain is on the small ring up front and the small ring in back. I have Shimano 105 components. I tried adjusting the B-screw but that didn't help at all. What am I doing wrong? I can take the derailleur and press back on it, which effectively raises the chain away from the rest of the derailleur.
