Beads

Derk said:

Hi,

I hear an annoying sound while cycling on roads that are not 100% flat. It's
caused by the "beads" that are located on the rear brake cable underneath
the top tube. I tried several models and used a sticker to dampen the
noise, but it just goes on and on.

Does anyone have a solution and/or know if there are softer beads and/or how
can make I some out of a softer material?

Softer donuts are in your package along with the truing stand.

Thank you, Peter. I didn't remember if I asked you to send me some.
I used 2 kinds now (clear round ones and 5 sided black ones).
I already prepared myself for some unorthodox solution, because the sound is
driving me mad: lot's of uneven paved/cobble stone roads here.

Now there's a grouping of words one doesn't see every day.

Why use donuts in the first place? On my road bikes there is room enough
between the cable and tube to allow some rattling without the cable
hitting the frame. Donuts only bring the cable closer to the frame.

Ask any policeman why! Seriously, I keep my bike in the house and take it
downstairs when I go riding. To do this, I hold the top tube and using the
donuts, the brake cable doesn't scratch the top tube.

Yep, But they also avoid making scratches.......

However, if all donuts cause this sound, I'll take them off the rear brake
inner cable, since it's a horrible sound.

I do not use beads, and get no sound from the
brake cable under the top tube.

This is very dependent on the frame. I have
a frame with cable stops cast into the head and
seat lugs, so there is an exposed rear brake cable
running the entire length of the top tube, fixed
at the ends like a guitar string. On rough
surfaces it rings like a bell, there also
being no braze-ons to deaden the resonance of
the tube.

(It needs donuts, but I need to get some and then
undo the brake cable, and it's no surprise that
I haven't managed to do both of those tasks in the
last five years.)

Get another house with no stairs. You can wheel your bike in ;-)

Get a brushed titanium frame ;-)

Yes they all do IME and they make scratches too...sand on the top tube
and rattling donuts.

I'm perfectly happy where I live: close to the only climbs in the East of
Holland :-)

It *IS* a titanium frame!

What is IME?

I'll try the ones Peter sent me first. If they make the same sound, I'll
have to make a few out of polystyrene or so and paint them black. Most
probably the "weight weenies" will have those ;-)

What a day: I spent half of my afternoon trying to get the drive side part
of a 7700 BB out of my titanium Colnago frame, just to put a fresh layer of
anti-seize on it. That's the last time I'll ever use a 7700 bottom bracket.
This one goes into the garbage if I ever succeed in removing it. The left
side was out in a second, the right side seems to be welded.

My brake cable runs under the top tube with no beads.
While the many areas of the frame are dinged, scratched,
and chipped, the top tube remains pristine.
Pull the beads and ride with a clear conscience.

I use 3M paint protection film for cars on the parts of my frames where I
dont want the cable to rub through the paint on the frame.

Its completely clear so maybe you could cut a long thin piece and stick it
on the underside of the top tube? you wouldn't need the donuts then.

I went to a local automotive window tint store and asked if they had any
offcuts, they gave me heaps of it, so much I still have heaps left 🙂

I works a treat.
