Drive train noise

While I'm not /exactly/ sure what you're describing, it sounds like basic
derailleur adjustments are needed.

Not a quick fix, per se, but not an afternoon's work either. Here's a good
site (Park Tool) for the basics:
Front Der: http://snipurl.com/a403
Rear Der: http://snipurl.com/a405

If you haven't done this before, it's really not that difficult. Just be
patient and you should be riding silently again very shortly.

Let us know....

Shift to the big ring, shift up the cogset to the same ratio. The chain
tickling the big ring when in the small ring and smallish cogs is NORMAL for
modern multi cog bicycles...

On a triple, I've always assumed that crosschain clatter was a fact in the
smallest and biggest rings. In your experience, should you typically be
able to use all your cogs quietly when you're in the middle ring (In my
case, Ultegra crankset, 105 FD)?

For a triple, are some FD's better about this than others?

TIA

_ There are no quick fixes. You are supposed to live with this
design flaw, those are BAD gears. Only heathens would use them,
the noise is designed in to warn you from straying from the one
true way of the bicycle. Terrible things will happen to you if
you use those gears, even worse than ignoring chain
letters. However, should you wish to become a RBT apostate here
are your choices.

1. Buy a skinnier chain. 9spd chains come in different widths.
See

http://www.branfordbike.com/chains/chains5.html

If this works, it's by far the best solution as every other fix
has a potential problems that are worse the annoying noise.

2. Add chainring bolt spacers to your crank. These are small
washers that fit over the chainring bolts, they come in 0.6mm
size. However, this will likely mess up your front derailler
index shifting and is potentially hazardous if the space
between the front chainrings becomes wide enough that the
chain can jam in between the rings. Really you shouldn't do
this.

3. Buy a new bottom bracket with a wider axle. This has many
bad side effects, the Q factor is wider and the recommended
chainline gets messed up, again this may cause problems with
proper front shifting.

4. Switch to non-ramped chainrings. This will make your
front shifting less crisp and again will make a indexed
front shifter work poorly or not at all.

5. Buy a new frame with rear chainstays long enough to
allow you to use all your gears quietly. Xtra-cycle is
an extreme example of this.

_ There is almost always a gear combo on the big chainring
that is the same as small/small. Even with a triple
chainring and 10 speeds in the back it's hard to get
much more than 14 or 15 significantly different gear
ratios. Really only a foolish perfectionist would
insist on having those gears work properly.

Hi, I don't think you can use all 9 or 10 cogs, in any chainring, on a
triple. On my DA triple, I have it adjusted, so that I can use the
middle ring, with the 7 largest cogs. Although I almost always shift
to the big ring by the 5th cog. The DA shifters allow trimming in both
the large and middle ring. With the two positions, I can use the 2nd
largest cog, with the big ring. I prefer not to, because of chain
line, but end up there by not paying attention, from time to time.

On your other question, the DA triple has a higher capacity 23t, than
the other Shimano 9-speed road triples, which are 22t. The DA triple
comes with a 30-39-53, while I think the others are 30-42-52. Better
in some applications. I know when I was using the DA triple FD with a
Tiagra triple crank 30-42-52, it didn't shift as well as the Tiagra
FD, it replaced. It was a temporary thing, as I knew I'd be installing
the DA crankset. I'm sure the experts can give you a better, more
helpful explanation. And speak on Campagnolo, where I have no real
knowledge or experience.

Thanks, Jeff. Sounds like the next one is DA....

Yessir. If the shifter(like the 105 or 6500 triple shifter) has a trim
position, you should be able to use all the cogs while in the middle ring w/o
the chain hitting the adjacent rings or front der.

Either the 105 or 6500. It should be noted that the new 6600, '10s' triple
front der is not useable on a 52/42. The cage is so long on the back(like the
DA triple front der) that it rubs the 42t ring. It is for a 53/39/30 only. Too
bad and a bad decison on shimano, japan's part, IMO.

who can hear with the gatorbacks? or downhill at 35-40 following the
UPS train down a new DOT cut surface bridge...
I tried spacers. downhill/high speed routes-wheel spaced to left
uphill to right.
then there are chain/cluster/ring wear periods when there doesn't seem
to be as much or actually no noise from these usually noisy gear/chain
postions
and then there are periods of serious milling sensation from the
cluster area like maybe yawl leaving shavings on the road.
try changing to a worn chain for a few miles.
hey skip the wax. wax is stupid. wax is for candles not for kids.
