| 2909.1 | Top Tube Cable Routing? | MKOTS3::TCC050::LARSON | | Wed Feb 08 1995 12:14 | 10 |
| Ken,
It may be that the top tube has "internal cable routing". I have a Trek
road frame that has an annoying metalic rattle in the top tube, and it is
the rear brake cable banging against the aluminum top tube. There is
nothing you can do about it (that I know of).

| it sounds to me like a metal burr that broke off one of the
tubing pieces during manufacture -- like if the tubes aren't
nicely polished before assembly and then one of the rough pieces
gets broken off during assembly and becomes forever entombed
within the frame. Evidence of minor sloppiness in assembly
but nothing to worry about unless you're trying to shave
milligrams.

| Cant you shake it out via the Seat Tube?
I Know that some Pro-Flex's had an extra tube "glued?" in the Seat tube
at their bottom bracket to give extra strength. There have been reports
in the UK of this coming loose and sliding around.

| Re: .1
I also have a Trek with internal cable routing. The rattling that you
described only happens on bumpy surfaces (which describes most New
England roads). I've heard of people solving this problem by covering
the brake cable with a length of narrow foam pipe insulation, run
through the seat tube.
I looked for some of this insulation at Home Depot, but the narrowest
they had was a 3/4" inside diameter. They suggested I try a store that
specializes in refrigeration supplies. When I find some, I'll let you
know how it works out.

| 2909.5 | can probably shake it out | EXPERI::MENTAL | Got me a caffeine jones! | Thu Feb 09 1995 09:34 | 16 |

Well, I looked at it again last night... It does sound like a small
metal burr... It's in the top tube, and slides all the way from the
head tube back to the seat tube. I pulled out the seat post, and
there is a hole at the top-tube/seat-tube joint, so I can probably
shake it out of there.
The bike only weighs about 22 lbs, so every milligram we can
shave off will help 8^).
Thanks for the help - now we just need to get out and *ride* this
weekend.

| Just as well it's not titanium, then removing the burr would mean less
of a gain.

| 2909.8 | My rattle is from the cage mount hole plug(s) | MUZICK::MISKINIS | | Fri Feb 10 1995 14:02 | 8 |
| Hi,
Did you install a water bottle cage? My Peugeot frame had
little plastic caps filling the threaded holes for a cage.
When these were removed (broken off) a piece went inside the
frame (on both), and I have had a rattle ever since.

| 2909.9 | Service ?!? | JGO::GERRITSEN | | Tue Feb 14 1995 07:43 | 5 |
| If I bought a new bike and heard a strange noise/rattle inside it, I
would go back to the dealer. It should be his service to clear this.
Or did this occur after you added the bar-ends etc ?

Forgot all about this note...
The rattle seems to be gone - I shook the bike around with the
seatpost removed, and that must have gotten rid of whatever was in
there. The bike's been ridden hard with no problems so far.
