Rattling STI shift lever
Ray Heindl
bumps, and buzzes when I ride on coarse pavement. It's not the little
nosecone piece, which I've seen discussed here, but the small lever
behind the brake lever. If I touch the lever very lightly the noise
goes away. It only happens on the right (rear derailleur) lever.
The LBS says that a lot of them do that, and the only fix is to put a
rubber band around the brake lever to damp the vibration. Is this
really common, implying that it's a lousy design, or did I just get a
lemon? If it's a design flaw, are there any fixes that are less
aesthetically obnoxious than a rubber band?

think it is just poor design on shimano's part. There is a screw that
holds the small lever in place, you can see it by looking into the shifter
levers from the back and up. Make sure that screw is tight.

I have a new (2000) set of 105s and they don't rattle. Maybe they're still
too new, and the rattle will come after a few '000 kms. Overall, though, I'm
impressed. They feel signficantly "crisper" than my last Shimano STI system,
which was a '96 DA.

rear shifter also. Annoying as hell. - Jim

lost the screw that holds it together, twice. My LBS was able to
replace the screw both times. The last time, they tightened it, and
put a small amount of "blue" Loctite on it. Supposedly, the "blue"
Loctite can be broken free with a screwdriver, if needed. At any
rate, I no longer have a rattle, have not lost any more screws, and
shifter works as good as before, if not better. I am very satisfied,
and have 3000 miles since the fix, where before I couldn't get more
than 1000 miles "per screw." Lousy chip 'n' seal roads!

You're obviouly a connoiseur of fine cycling hardware. As such, you'll
want to buy the Alfonzo de Credenza "Bando Rubbero," handcrafted by
Italian artisans, and imported in small quantities by my company,
Voler-par-Nuit Bicycle Cogniscenti. We usually sell this fine product for
$99.99 / set, but for the month of May, I'll ship them to any active
member of rec.bicycles.tech for only $99.95, plus taxes and
shipping. Please specify the desired colour (extra charge for chrome
plating), and prepay the total due in small unmarked US currency.

That's just fine and dandy if you are riding that furrin bike. For good
all made in the USA bikes I will sell you same thing for half the price,
49.99 and it comes with a lifetime guaranty with no questions asked replacement
policy. You lose it, I'll replace it for free. I only charge $4.99 for
shipping and handling. Cash is the prefered method of payment.

Use a screwdriver or such and pry off the plastic cover (don't catch the white
plastic piece under the cap). Use a small Phillips screw driver to tighten the
white plastic bit underneith, and pop the plastic cap back on.

But does it come with chrome plating? And a fancy Euro-style logo?

I think they're talking about a different issue...the inside lever rattling
against the main lever. OK, if you want to get technical, Shimano calls
them "blades." They're on the right track (tightening that small phillips
screw on the inside ever). And, sometimes it helps to simply bend the
inside lever a bit so it doesn't hit the larger one when it returns.

I tried to tighten that screw but it wouldn't. So I loosened it a little and
then re-tightened it. Went for a ride and so far the noise is gone. Thanks. -

Looking at how the small lever fits inside the brake lever, I could see
there was only one small area of contact. The finish was slightly worn
in this area, from vibrating against the brake levers. So, I stuck a
small piece of plastic electrical tape on the small lever in that area,
and the rattling noise went away. The piece of tape was pretty small,
and mostly hidden by the brake lever, so it was practically invisible.
Based on the inputs from the NG, I tried tightening the screw at the
top of the small lever. That also solved the problem, and without any
tape. If it comes loose again, I'll try putting loctite on it.
Too bad Shimano used a Philips-head instead of a socket head; it's had
to get much torque on that screw because you can't (at least on my
bike) get a straight shot for a screwdriver.
Thanks everyone for all the inputs.
