VERY stiff Ultegra front shifter(6 posts)

VERY stiff Ultegra front shifterPdxMark

A friend has a new Ultegra bike with a triple front derailleur. The rear shifting is fine, but shifting to the outer ring in front is very hard - taking a concerted effort for me to do and not always being successful. The friend, a fit woman, can't get it shifted. It's that stiff. What's up? Is there an adjustment somewhere or is this a good time to use the "return in 30 days" option?

It is probally time to replace the lever!

This is not the normal operation of Ultegra. The shifting system is either badly maladjusted, or there is something which is restricting the motion of the front derailleur or the shift cable itself. A quick trip to a bike shop with a skilled mechanic will alleviate the problem.
Take it to a shop or DYIKerry

If you want to check this out yourself, the first thing to do is separate the lever action from the derailleur action. Disconnect the cable and operate the derailleur by hand. If it shifts easily to the large ring, then the problem is the lever. I'm guessing that the outer limit screw is in too far and therefore making it hard for the derailleur to get the chain up to the big ring. If it is the levers instead, first try sluicing them out with solvent (like WD-40) and then chasing that with lube, all the while shifing up and down to work both the solvent and the lube into the mechanism. If the front derailleur is OK with a proper limit screw adjusment and the sluice and lube doesn't help the shifter, then you're probably buying new levers. Not likely, but that's the path you follow to find out.

There is a possibility that the cable is incorrectly attached at the fixing bolt on the FD. If the FD fails or you can't correct the problem, try using a 105 triple FD, I am using one and it has a much lighter spring action= easier smoother front shifts. Doubtful that the problem is in the STI. I give mine a full firm positive twist to shift and it is very smooth.
