Problem with my new derailleurs
#1
Okay so I decided to upgrade my front and rear derailleur, and at the local bike shop I bought a shimano front derailleur, a shimano Sis rear derailleur, and rapid fire shimano Sis shifters. I installed them quite easily but my problem is the tuning, my front derailleur wont shift at all, its on the lowest gear, while my rear derailluer shifts from gear 2 to 6 (18 speed bike).

I noticed on gear 5 and 6 of the rear derailleur the chain remains on the lowest gear. Also I have a barrel adjuster for the rear derailleur but not the front.

Welcome to BT, socialfox!
It is always a great help on these type questions, if we know what parts we are dealing with. Your shifters, for example, may be ST or SL-570 or something like that. It's somewhere on each part but also on the box if you still have it.

There is usually a barrel adjuster on the Rapidfire shifters, where the cable exits, and that is what is used for the front derailleur adjustment. It sounds like the system just needs setting up.
