SOURCE: broken shimano 105 flight deck shifter

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.

SOURCE: How do I replace rear shifter cable in shifter

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.

SOURCE: shimano tiagra 9 speed shifters how to change gear

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.

My shimano ultegra left shifter is super stiff/hard to push in; what is going on?


Try flushing out the shifter(s) with WD-40, use plenty. The next step will be replacing the shift cables and cable housings.
  • Take the bicycle in an area free of cars and obstacles, such as an open parking lot. Concentration is required when learning to use Ultegra shifters or any other type of bicycle shifter.
  • 2 Mount the bicycle and rest both hands on the proper Ultegra hand control. The left-hand control operates the front derailleur. The right-hand control operates the rear derailleur.
  • 3 Start pedaling, smoothly and evenly. While pedaling is crucial to propelling the bicycle forward, it is also necessary when shifting the derailleur. Pedaling forces the chain to rotate. The chain must rotate before it can transfer to another gear.
  • 4 Push the outside right Shimano Ultegra lever in toward the bicycle. The rear derailleur will shift the chain to a smaller rear gear.
  • 5 Push the inside right Shimano Ultegra lever in toward the bicycle. The rear derailleur will shift the chain to a larger rear gear.
Rear Ultegra Derailleur Control
  • 1 Push the outside left Shimano Ultegra lever in toward the bicycle. The front derailleur will shift the chain to larger front gear.
  • 2 Push the inside left Shimano Ultegra lever in toward the bicycle. The front derailleur will shift the chain to a smaller front gear.
  • 3 Use the front and rear Ultregra hand controls interchangeably. For small changes in gearing, using the rear control. For larger changes, choose the front control. A smaller gear causes the bicycle to travel a shorter distance per pedal stroke but also requires less energy to use. A larger gear requires greater effort but in turn causes the bicycle to travel farther per pedal stroke.

Shimano 105 front shifter problem


There will be adjustment, check the front derailleur. There is a wire which is held by a pinch bolt, undo the bolt pull the wire out a little, tighten up and check the gears again. Do this until it works.

Shimano Deore LX right hand rear shifter


HERE is Shimano's exploded-view diagram of the shifters, but it really only gives you a ballpark idea of the assembly. You will have to piece the rest together from memory, i suppose. Sorry, i could not find more information for you.

Hope this helps a little,
