Similar advice to Phish;loosen cable from ft derailler and make sure the derailler is adjusted correctly over the inner chainring, then downshift by pushing inward using the the small inner sti shift lever(the lever that does not engage the brake) while pulling on the cable till it no longer clicks. You should now be "bottomed out" where the the shifter has reached its limit and now fasten the cable to the derailleur with tension on the cable and all should work now. As the cable stretches you can make minor adjustments for cable tension with the adjuster on the headtube or downtube. Same goes for the rear derailleur where you start with the chain on the smallest rear cog(where there is least tension on the cable--adjust the rear derailleur to align properly with with your small cog,click the rear shifter,again with the small inner shift lever while pulling on the cable til it stops clicking. Put tension on the cabe and attach to rear derailluer. Cable tension on the rear shifter is more critical than the front as in if the cable stretches the rear derailluer will not line up properly with the cogs. Use barrel adjuster located on the rear derrailuer or downtube. Hope that helps.Let us know what happens.
