I just bought a 01 Lemond Zurich and it seems to be a very well made and tight bike except that the (ultegra)levers rattle like crazy on rough roads. I applied a small coating of clear RTV under the hoods thinking that that would help shim things up, but they still rattle. ...maybe I didn't use enough...? (of course I rubber banded the brakes on to let the stuff dry first)

Anyone out there have a fix that works well?

... unusual, cuz the new Ultegra has a built in fix... Here is the solution from Chain Reaction...

If you've got older levers, this may solve the problem. If you've got newer stuff (Chrome dust covers ala Dura Ace) then I'm stumped.

Be the bike.

Check the small screw that holds the small inner lever on. Its on the inside of the levers. Make sure you use a little red locktite, they have a bad habit of coming loose.

Thanks for the ideas, They are 01 integra levers with the little chrome metal hoods. I will have to do some more experimenting as see what works. The rest of the bike is solid as a rock, but the levers make it sound like things are falling apart.

1. The plastic caps on the 1st generation 9 speed fit loosely. Silicone under the caps ala www.chainreactionbikes.com Dunno about the latest generation - they said they fixed the problem, but a quick look left some doubts in my mind. I don't have any time messing with these yet, nor have I seen anything in print.

2. Little screw on the back of the big lever that keeps the little lever in it's correct relative position comes out and lets the whole works rattle around. Fabricate a new screw using a SS metric screw and use BLUE Loctite.

3. Levers move down and snap back when going over bumps due to inertia and low return tension. Check to see that brake cables are snug.

No reason why you can't have a perfectly quiet running bike if you work at it. However, they should come this way.
