The stem on my Cannondale T800 is creaking when I twist the handlebar along
the stem axis (when riding hard for example). The bolts are already very
tight so I don't think the problem comes from that.
I was thinking about applying a bit of grease (or wd40?) between the stem
and the steering column and the handlebar, but I have read conflicting
advice about doing this. Some people say you should never grease a
threadless headset whereas other say that a big of grease helps with
creaking noises. I don't have a carbon steerer (I think it's just steel or
aluminium) so maybe grease is ok?
Cheers,
Arnaud.
This usually comes from the place where the stem meets the steerer tube.
Definitely remove the stem, grease the outside surface, and replace the
stem. This will not cause any harm at all. Failing to do this may cause
harm, so do it.
The noise sometimes comes from the place where the handlebar meets the
stem. This can be less convenient to grease.
These noises often come from much more mysterious places, such as the
place where the pedal meets the crankarm. Soemtimes, it's the saddle.
And you could swear it's coming from a different area of the bike.
Lubricating these surfaces is never harmful.
