|Ultegra Shifting Problems||Jaybo|
Mar 4, 2002 10:10 PM
|I just put Ultegra shifters on a brand new bike with new cables. The problem I'm having is when I shift from the 14 tooth to the 12 tooth I get two shifts in the indexing. The shop told me the Ultegra shifters tend to have some sticking problems and it should work itself out eventually. I have also heard that Ultegra shifters sometimes are defective. What do you think? I have the new 2002 shifters. I kinda wish I would have stepped up and got Dura Ace. Oh, I'm also getting a buzz from my left shifters on rough ground. I hate that. Thanks.|

|hit the barrel adjuster on your rear derailleur. it's not (imho) a 'sticking problem'.|

|My bet is that your shift cable is too loose.
First disconnect your shift cable entirely and turn your crank. The derailleur should shift onto your hardest gear. Check to see that your upper jockey wheel is directly under the smallest cog.
Now grasp your shift cable with needlenose pliers and pull it tight with your left hand. Tighten the fixing bolt with your other hand.
Try shifting through the gears, make whatever fine tuning adjustments are necessary with the barrel adjuster. You're good to go.
|Agree, tension problem, more than barrel adjuster (nm)||Chen2|

|I had that buzz in the left Ultegra shifter as well. My problem was that the brake cable had about 1 inch too much housing making a bit too sharp a bend down to the caliper. Even though I didn't feel any sticky-ness in the cable, when I took out that slack, the cable was able to return the lever back nice and tight and the buzz went away. Maybe you have the same situation.|

|I used the fix below on my '99 Ultegra levers, worked perfectly. I have read that this "rattling" was to have been addressed by Shimano on new versions however, something about now utilizing similar internal construction to Dura Ace...
Hope this helps.

|specifically, they now use ball bearings instead of bushings. I think.
as for the rattling, see http://www.chainreactionbicycles.com/noisystilevers.htm
|My buzz not loose nameplate - Any help?||velolover|

|See my post yesterday. I have a buzz in my right '99 Ultegra shifter, but it's not the nameplate that the Chainreaction site talks about.
Someone told me that it's common with Ultegra that a little screw on the upper back side of the large shifter blade gets lost and then the two blades rattle together.
Anyone know what I'm talking about?
|yes, clean and put locktite on it. Works pretty well (NM)||Woof the dog|

|Happens a lot - just make sure you use BLUE loctite (medium) RED is more permanent. If you've been having this problem for a while you may not be able to fully tighten down the screw w/out jamming up the levers, so Loctite is really necessary.|
