cannondale frame under stress

It's normal. It could be the seatpost, bb, saddle rails, just about any contact point. Greasing
these points might get rid of it. If it's the bb, try some teflon tape. Let's not turn this into an
alu bashing thread. "hans" <[email hidden]> wrote in message

Hi,

I got myself an F500 last year and recently I hear this "tinckling" noise whenever I shift my
weight on the sadle or when I hit some small bumps in the road sitting down. I cannot pinpoint
where the noise comes from but it is approx. from where the sadle bar is entering the frame.

It sounds like trouble but since this is the first alu frame I got I'm not sure. Before I go back
to the shop with it I would like some advice: is this normal behaviour of an alu frame under
stress? Or am I wrong in looking at the frame?

Thanks,

Hans

Could be almost anything, but I'd be looking at the saddle first - the junction of the rails and
the seat body, then the connection of the seat rails and the clamping mechanism, then the seat
post and the frame. There are various ways of lightly lubricating these, and dissassembly is the
most thorough.

Hope this helps, cheerz, Lynzz

Probably not anything significant; I've had several bikes that have made similar noises when
mounting up. None had aluminum frames, and all of the noises eventually went away either when I was
doing something about a different issue (just adjusting the seat angle did it once) or with time.

My handlebars did the same once. As soon as I stood up and put some weight on them. It dissapeared
immediately when I greased and retightened the bolts holding it.

I mostly agree with the rest. Whenever my F1000 did that, it was ususlly that the seatpost needed
lubbing. Less often, it was the seat rails -- or even the pedals (the clamping mechanism needs lube
where they pivot). And remember that noise travels in a frame and it's really hard to pinpoint
where it's coming from. Other places: headset, bars, pedals where they thread into the cranks,
cranks, etc...

But, I broke my 1st Jekyll frame where the top tube welds to the seatpost tube (no questions asked
replacement). It was a medium frame, I should have had a large (I wanted a little more clearance
between my jewels and frame 🙂) so I had a very long, setback seatpost (410mm). I also ran a
seatpost rack for a while -- so there was __ALOT__ of stress on the seatpost and frame. I would keep
an eye on that weld if greasing doesn't take care of the problem.

In Cannondale's favor, they could have called it abuse, and the weld held even though it was broken
1/2 way around with I finally noticed it! The replacement's a Large and it fits much better 🙂.

Greasing and tighting the seatpost and seat at the seatrails might work. Don't forget to tighten the
crank and chainring bolts also.

I'll add more possible source of sound: my neighbour had a "tinckling" in his bike. Turned out to be
the front derailleur that had ever so slightly loosened......

I've never had such a sound from either of my aluminum bikes, a GT and a Giant. You should try to
duplicate the sound with the bike on a stand or on the floor, and see if you can locate it.

It could be the spokes. Check if the are properly tensioned.
