Sticky Ultegra Shifter

My right side 2005 Ultegra 9-speed shifter has a sticky inner black lever (the one that downshifts to smaller cogs). This started happening after about 1000 miles of light use in fairly normal conditions. Taking the the lever off and lubing it with TriFlow or grease fixes it for a couple weeks, but it eventually starts sticking again. The brass pin that the lever pivots on and the sleeve in the lever that fits over it look smooth and clean to the eye. Anybody ever have or solve this problem?

Do a search on this in these forums and you'll find this problem over and over with the Shimano levers. Some folks have been able to fix this by flushing the shifter with lubricant. It didn't work all that well for me so I switched to Campy since I could get the shifters much cheaper.

How old are the cables and housing? My 105 rear shifter was kind of sticky also, but when I looked at the cables and housing (after about 1500 miles on the bike), I noticed that they were slightly rusted so I replaced them. Now my baby shifts like a dream!

Good well be that you need new cables and cable housings. A dirty or corroded short housing at the rear derailleur is often the cause of poor shifting performance.
