Temporary shift lever repair ???(6 posts)

Temporary shift lever repair ???superdog

I searched the archives using the keywords "sticky" "shift" and "lever" and I couldn't find much so I'll ask this question again:

My right shimano ultegra shift lever is sticking. I have to push the black (inner) lever both ways to shift through the cassette. I have a race on Saturday and no bike shop can fit me in before then. So... I am trying to get a temporary fix and then take it to the shop next week.

The lever does have some black gunk on the shift mechanism. I was thinking that it wouldn't hurt to wipe as much gunk off the mechanism as possible and squirt some lube into the lever.

First, I don't know if that will fix the problem. Second, I don't know what type of lube to use or if I should squirt anything in there. Anybody have any suggestions? I really need to buy a good maintenance book so I don't have to rely on the shop.
Squrit some tri flow in tere and see what happens.nmthe bull

Use a solvent to get your gunk out, a can of "electrical contact spray cleaner" will work best, and won't harm your paint. Then use a light lube, like wd-40, triflow, etc.

ALSO: get your shop to warranty the ultegra lever if it's anywhere near new. Shimano had LOTS upon LOTS of ultegra 2002 and 2003 levers returned for sticky operation. It's their problem, and if your shop is a nice shop, and knows a nice rep, then they won't give you a hard time at all about warrantying the shifters. They should do this, no problem, just for the sake of making you happy and being a good shop that stands behind product.
WD40 is NOT(!) lubeKerry

Sluice it out with WD40 (essentially aerosol kerosene) and THEN add a light lube, like TriFlow. You need to flush things pretty well. If that doesn't restore function, then you're looking at defective parts.

I just happened to have a can of electrical contact cleaner and it really took the gunk off the lever mechanism. I lubed it with tri-flow after. It now shifts well. Thanks for the info.

I had the same problem two weeks ago. I tried the mentioned "fixes" and it didn't help. I got lucky w/ my LBS having the shifter in stock and got me going the next morning. I was able to downshift but both levers would move on the upshift. Each time I had to fumble upshifting, I dropped back a few lengths and had to work hard to gain the distance back. If you can get through the weekend, one of the "hot deals" has that shifter for less than $60.
