Another post concerning sticking Ultegra lever(12 posts)

I'm so broke I can't even afford to buy a new shift lever. My right Ultegra lever is sticking and I'd like to know if this can be fixed or should I just park the bike for a month until I can afford to buy a new lever. (right hand lever)

When I shift the inner black lever, the outer silver lever travels along with it which causes it not to shift. If I carefully hold the outer silver lever while I shift the inner black lever it shifts fine. I can't race like this though.

I used to have a sticking problem of a different nature but I solved that one by spraying the lever guts with electrical contact cleaner and then squirting a lot of Tri-Flow in it.

I'm wondering if the spring is going bad. I hope this can repaired so I can get through one more month. Just one more stinking month.

Does the Ultegra lever have a lot of sticking problems? Is Dura-Ace more reliable? What about campy? I don't recall ever seeing a post complaining about campy levers sticking.
If it's more than two years old, you'll have to fix it yourselfMR_GRUMPY

Any product has a certain percentage of failures, you just got unlucky.
Try the WD-40, sometimes it works.

Check under the main lever for a small screw. If the screw has backed out it will cause the outer lever to move with it. On an earlier set of Ultegra levers I had the same issue after the screws loosened.

I second what johnrg said. With a good disassembly, cleaning and re-assembly you can solve alot of problems. I found a service manual for disassembly of STI levers online some time ago. Try to find that, or I can fax it to you if needed. johncboyd at yahoo dot com.

I don't have a fax. What is the exact title of the manual? ...and maybe a few key words. I'll do a web search.

Either Shimano.com or branfordbike.com You'll need to drill down to find it, but I was able to.

If you're able to re-build it, post it. Also, some guy has a website devoted to rebuilding these; you could probably google it to find it. Might be linked from branfordbike.com

PS: Hate to burst your bubble, but once the inner lever sticks and the WD-40 / Tri-flow trick fails, the shifter is toast. Servicing them is near impossible for mortals.
I fixed it! Yipeeee!superdog

I looked for the little screw on the underside of the levers to see if it was loose. It was completely missing. I took the screw out of the other lever and went to Lowes and purchased six screws. I always buy spares.

The head on these screws are a little thicker than the Shimano screws but it does not seem to make any difference.

Thank you all for your input.

And put some blue loctite on the screwsLone Gunman

I had the same problem, except I did not lose the screw. I did remove and loctite them, not loose since.
Good advicesuperdog

One of my new screws already came loose on the first ride.
