Derailleur adjustment advice
The rear Derailleur has started to hesitate---or not shift at all---
during normal shifting. It's Ultegra with STI's. My first thought was to turn the barrel nut counter-Clockwise (tighten the cable). However that didn't work. What else can it be? Thanks, Bob |

See: http://www.sheldonbrown.com/derailer-adjustment.html If the "hesitation" only happens when shifting to a smaller sprocket, the problem may be friction in the cables/housings or the BB cable guide. Might also be the STI lever going south. Art Harris |

Re: Derailleur adjustment advice
http://sheldonbrown.com/derailer-adjustment.html has all the info you need.
From your description the problem could be: (a) cable tension, though you didn't specify whether the hesitation is shifting up or down or both (b) other cable problem, such as dirt or fraying inside the housing, that prevents normal motion (c) derailleur needs lubrication (d) derailleur hanger bent (e) internal shifter problem Let us know what you find.

Unhook the cable and push the der up the cogset while pedaling....in the stand...does it go up and down smoothly? Then it's related to either adjustment or the cable/housing.
