Help! Frozen Stem in Fork

Larry Desay said:

Anybody, I installed an aluminum stem in a carbon fork/steel steerer
tube and it's in tight. No way do I want to twist the stem from the
fork. I cut the stem from the quill to remove the fork from the
frame. There is about 3/4 inch of the quill extended from the fork.

After reading some methods from Jobst Brandt I feel this may
necessitate the skill of a good frame builder.

It's amazing to me that no one has come up with a boot or adequate seal
to keep sweat from getting down into this joint.

Rather, it's not widely sought for and adequately implemented.
A mylar shim would just do the trick.

For years Campagnolo and Shimano, as have others, offer their threaded
headsets with a seal in the lock nut. In spite of this, they suck
sweat into the interface because the stem wobbles from side to side,
something most seals do not handle well.

The problem should vanish as bicycles in general switch to threadless
headsets where the stem is securely attached and is not prone to
corrosion in a fretting gap. This is the main improvement this design
has brought with it. The threadlessness is immaterial and an
unfortunate naming appendage. It is the first bar stem since the days
of yore when Cinelli track forks had an expander at the bottom of the
stem and a clamp at the top.

If you fitted the stem with a liberal amount of anti-seize you could
then seal round the top with clear silicone. It's not so strong that it
would stop you getting the stem out again, and hopefully the need to
regularly remove and regrease it would be eliminated as there would be
no sweat/rain getting down there.
