You may have broken your derailleur cable. Your cable securing bolt on your front derailleur might have worked loose just enough for the cable to get some slack in it so that your derailleur isn't moving. Try completely loosening the cable bolt at your front derailleur. Pull on the cable and click the control to downshift to the inside crank gear . That should remove all the slack from the cable. Worse case scenario is when you pull on the cable it will completely pull out and it has broken at the shifter. You will have to replace it with a new one. If it isn't broken and you can still shift with the cable make sure your limit screw is properly adjusted for the inside crank ring and then pull all the slack out of the cable with the shifter shifted to that gear. Tighten the bolt that holds the cable in place and try the shifter again. It should now shift normally. If it doesn't you will have to take the bike in to have the shifter repaired. These shifters are not easy to repair unless you have the tools, parts and experience. Hope this helps.

ok this is a little hard to explain in words but the important thing is to make sure the chain is on the biggest cog, pull the cable through the deralier tight and fasten. don't pull it too tight however. you may need to fine tune using the h/l screws but if it was in tune before then it shouldn't need too much adjustment.

Go to http://techdocs.shimano.com/techdocs/index.jsp
Search in drop down list to go to all tiagra items and identify your particular components. Shimano are good at numbering their parts and you should find the number you seek on the bicycle component. You will usually be able to download an exploded parts diagram and service instructions. The service instructions are prefixed by the letters SI.

log onto Shimano.com, it is probably the limit screws (the two screws that limit travel) or you have a faulty ratchet in the lever, try the shimano website anyway they have great tutorial and manual support
