Noooooobie question about gears
I just picked up my new bike [see here!] and riding it home with the chain on the biggest front sprocket it was rubbing against the front changer... now I know there are two little screws on there to adjust this, but what do I gotta do to sort it out?

Another thing to consider, when in the biggest chain ring try not to have the chain on the lowest gear (largest cog) on the back. It will can cause the chain to rub the front derailer and put undo stress on the chain. If you are running the biggest cog on the rear use either the granny gear or the middle chain ring.
