Shifting Problems

    I just replaced both brake/shifter pods with new ones on my Specialized Rockhopper Criterium, 1994 model (approx). The new brake/shifter pods are Shimano V-Brake CI-DECK PLUS. The derailleurs are: front - Shimano ALTUS A20 and rear - Shimano ALTUS A10.

    Also, the rear cluster is composed of 7 gears.

    The problem is this, with the chain on the middle chainring, upshifting from 4'th to 5'th is a problem. The derailleur moves but the chain fails to transfer to the smaller sprocket. Instead I need to upshift to 6'th gear from 4'th and then downshift to 5'th.

    How do I adjust these babies, these indexed shifters? Just an fyi the last time I dealt with bikes was my 1986 Schwinn Cimarron. The components on that model were simpler, much simpler than this new fangled stuff.

    thanks, all.

    Thanks, Rek. Yeah, that's what I'm told. And the Park Tool website is really a boone to me.

    Also, just an fyi to you all, I readjusted the rear wheel a couple of millimeters in the dropouts (it's a quick release) which solved MY problem.
